Как сверлить бетон: правильная технология, инструмент (видео)

Как сверлить бетон? Такой вопрос часто возникает у мастеров во время строительства и ремонта жилищ с бетонными стенами. Сверлить бетон приходится, чтобы установить электрические розетки и выключатели, проложить трубы, провода и другие коммуникации.

При сверлении бетона перед новичком возникает масса проблем, таких как поломка сверла, или даже дрели.

Бетон — очень прочный материал. Сверлению обычными способами он поддается очень плохо. А если он армированный (железобетон), эта задача становится практически невыполнимой с помощью обычной дрели. Как просверлить бетон? Проблема проделывания отверстий в этом материале становится все более популярной.

Чем сверлить бетон?

Основными инструментами для сверления подобных конструкций сегодня являются дрель, оснащенная ударным механизмом, и перфоратор. Правильно сверлить бетон перфоратором. Он предназначен именно для такого дела. Отверстия, проделанные перфоратором, могут иметь достаточно большие размеры как по их глубине, так и по диаметру. Просверлить стену можно с использованием специальных рабочих инструментов, имеющих твердосплавное напыление или победитовые вставки . Наиболее распространено несколько способов применения этого инструмента:

Наиболее мощным инструментом для сверления бетонных конструкций является перфоратор.

• использование обычного инструмента с дополнительным применением пробойника;
• применение перфоратора или ударной дрели, укомплектованных специальными инструментами;
• бурение алмазными инструментами.

Обычным способом проделать отверстие в стене очень трудно, и дело это занимает много времени. Инструмент быстро тупится и выходит из строя. Как правильно сверлить стену? Точка сверления должна постоянно получать вращательное и ударное воздействие. Вращательное движение достигается с помощью дрели, а ударное — с помощью пробойника и молотка. В качестве пробойника может использоваться старое сверло. Молотком наносятся удары по его торцу. При этом частично происходит разрушение слоя бетона. Разрушенные частицы удаляются с помощью дрели. Отверстие медленно, но углубляется. Самый распространенный метод — проделывание отверстий перфоратором и специальным режущим инструментом. Работа идет довольно быстро и качественно. Небольшой объем работы можно выполнить ударной дрелью с твердосплавным инструментом.

Алмазное бурение применяется при достаточно больших объемах работы. Этот метод позволяет справиться с делом очень быстро и без большого количества пыли. Как получить отверстия большого диаметра? Это делается с помощью коронок с алмазным напылением или твердосплавными вставками. В отдельных случаях используются специальные установки с водяным пылесосом. Но обычно с подобной задачей вполне справляется перфоратор. Сверло из отверстия рекомендуется периодически вынимать и смачивать водой.

Инструменты, вставляемые в патрон дрели, обычно выпускаются диаметром от 4 мм. Наибольший диаметр — 1,2 см. Длина их может составлять 40 см. В готовое отверстие вставляется дюбель из пластмассы, и в него вворачивается саморез. Диаметр дюбеля должен совпадать с диаметром отверстия. Для подвешивания шкафов и других предметов мебели рекомендуется сверлить отверстия и пользоваться дюбелями диаметром в 8 мм.

Сверла для перфоратора

Сверла, применяемые в перфораторе, принято называть бурами. Буры могут иметь диаметр от 4 мм до 28 мм. При этом они имеют различную длину (диаметр и длина в миллиметрах):

Схема устройства сверла.

• 4 — 50;
• 5 — 100;
• 6 — 150;
• 8 — 250;
• 10 — 540;
• 12 — более 1000.

Бур для перфоратора имеет хвостовик типа SDS-plus. В промышленных установках могут применяться другие хвостовики. Проделывание отверстий диаметром от 35 мм осуществляется инструментами, которые в народе называют коронками. Максимальный их диаметр — 12 см. По периметру коронки располагаются напайки из победита или алмазное напыление. Коронками работают без включения ударного механизма. Отверстие высверливается за несколько приемов, чтобы режущий инструмент и двигатель остыли. Коронки хорошо сверлят кафель, поэтому облицованные кафелем бетонные стены можно сверлить без смены инструмента.

Приобрести специальные буры и коронки можно в многочисленных магазинах инструментов и строительного оборудования.

Рекомендации по сверлению отверстий

Несколько советов:

Схема сверления бетонной стены.

1. Перед креплением инструмента в патроне перфоратора или дрели необходимо очистить его от загрязнений.
2. Хвостовик бура должен входить в патрон до упора.
3. Для бытовых дрелей и перфораторов через каждые 15 минут работы нужно делать перерыв на 10-15 минут.
4. Сверло рекомендуется периодически смачивать водой.
5. Перед проделыванием отверстий в стене необходимо убедиться в отсутствии в ней труб и электропроводки.
6. Чтобы найти в стене трубы и провода, можно использовать металлоискатель.
7. Начинать работу следует при выключенном ударном механизме и на малых оборотах.
8. Глубина отверстия должна немного превышать длину дюбеля, который будет в него вставляться.
9. Глубину сверления можно отметить, навернув на сверло виток изоленты.
10. При работе рекомендуется использовать средства индивидуальной защиты.
11. Лучше покупать буры известных производителей. Отличный выбор — изделия фирмы Bosch.
12. Алмазное инструмент поможет быстро и качественно просверлить много одинаковых отверстий.
13. Сверла и буры по бетону нельзя использовать при сверлении металла и древесины.

Сверление бетонных стен — это не очень простое занятие, но вполне выполнимое даже в домашних условиях.

Отверстия обычно бывают нужны при навешивании отдельных шкафов на кухне, при установке розеток, выключателей и распределительных коробок при монтаже электросети. Для работы понадобятся хорошие сверла и коронки, перфоратор и ударная дрель. Все остальное — дело времени. Навык нарабатывается очень быстро.

90000 How to Drill Concrete: An Easy Step-by-Sep Guide 90001 90002 Construction projects are endlessly rewarding until you come across a problem that you can not quickly solve. Struggling to understand 90003 how to drill concrete 90004 can be one of those situations. While concrete is a versatile material with a sought-after industrial aesthetic, its durability can quickly become too much of a good thing if you can not make it behave. 90005 90002 If you’ve tried to understand how to drill concrete with the tools you had on hand, you likely met with failure within moments of trying.The good news? There are special tools designed just for concrete construction, and they can make a world of difference in how to drill concrete. 90005 90002 We learned this lesson ourselves in the midst of building our own debt free timber frame home (check out the timber frame workshop we did), and we think the lessons we learned are valuable enough to pass on to you. If you’d rather watch our experience, this video shows the process of us learning how to drill concrete the right way. 90005 90002 90011 90012 90005 90014 Hammer Drills: The Best Way to Drill Concrete 90015 90002 The key to success for drilling concrete is relying on a hammer drill (also called a rotary hammer) for the job.90005 90002 A quality hammer drill can bore down over two inches in solid concrete in just a minute, which is significantly faster than any rotary drill. These tools work by fracturing the material through a rapid hammer action and then scooping out the broken rock and dust through drilling. 90005 90002 90021 90005 90002 If you do not plan on using one enough to justify owning it, hammer drills can be rented by the day for about $ 50. When you look for the right one for your needs, pay attention to its power level, whether it has more than one speed, and if it has a stop function for safer drilling.90005 90002 We bought the Mikita model hr2811F hammer drill for our home build, and could not be happier with the decision because it offers us the flexibility to take advantage of a high powered tool whenever we need it without having to get a rental every time. 90005 90002 Check out our unboxing of this hammer drill below. 90005 90002 90030 90012 90005 90033 Which Drill Bit Length is Best for Hammering Concrete? 90034 90002 Prepare to be shocked by just how large a drill bit is needed to drill concrete.You will need to choose a screw length that can penetrate the material by at least one inch. 90005 90002 We needed to drill through three and a half inches of sill plate, and eight inches in concrete, so our bit was significantly longer than this. 90005 90002 90040 90005 90002 High-quality masonry drill bits work best, and a carbide-tipped bit will better withstand the force of hammering and drilling. Make sure the flutes on each drill but are as long as the hole you plan to drill, as they are responsible for pulling the rock dust out of the hole.90005 90002 Some rotary hammers require special drill bits that are called SDS, SDS-MAX, or Spline-Shank, so pay close attention to the requirements for your tool. 90005 90014 How to Drill Concrete in Seven Steps 90015 90033 Step 1. Prepare the Drill Bit 90034 90002 Use a pencil to mark on the concrete where you want to drill your hole, and double check every measurement before moving on. This is also a good time to determine how deep you want each drilled hole to go. 90005 90002 If included, you can use the drill’s stop bar to set the exact depth you want each hole to be.Do not worry if there is not a stop bar; just wrap a piece of tape around the drill bit at the desired length instead. 90005 90002 90055 90005 90033 Step 2: Get in Position 90034 90002 Put on safety goggles (and your favorite construction work clothes!) And insert your drill bit into the drill. Get into a safe drilling position by standing upright, with the tool secured in both hands. 90005 90002 The best hand stance is to hold your drill like a handgun and keep a grip on the auxiliary handle for extra control.To ensure you get a straight hole, the drill bit should be perfectly perpendicular to the concrete before you begin. 90005 90002 90064 90005 90033 Step 3. Make a Guide Hole 90034 90002 Turn your drill to the lowest setting, and work in short, controlled bursts to create a guide hole about a ¼ inch deep. This will increase the drill’s stability as you drill the real hole. 90005 90033 Step 4. Start Drilling! 90034 90002 Carefully place the drill into the guide hole and begin drilling down with a steady hand.You can turn the speed up if you feel confident, drilling down into the concrete until you reach the stop bar or scotch tape. 90005 90002 Keep in mind that concrete is filled with air pockets and small pebbles that can quickly change the resistance level of your drill, making it easy to lose control if you are not careful. Never force the tool through if you hit obstructions, as it can damage the bit or cause you to lose control and damage the concrete surface. 90005 90002 If you hit pockets that you can not drill through, set the tool down and use a masonry nail and hammer to carefully chip through the obstruction.Afterwards, you can continue drilling at a slower speed. 90005 90033 Step 5: Remove the Dust 90034 90002 As you drill, you should periodically stop to pull out the tool and brush away the built-up concrete dust. Pausing your progress every twenty seconds is a smart idea, and it also prevents the rotary hammer from overheating. 90005 90002 90083 90005 90033 Step 6: Complete the Hole 90034 90002 Once you’ve reached the right depth for your hole, pull out the drill and blow out any remaining dust with compressed air, following afterward with a vacuum to get everything that falls to the ground.90005 90002 Wearing your safety goggles is still crucial during this step, as concrete dust is highly irritating to the eyes. 90005 90033 Step 7. Start the Next Hole 90034 90002 You can repeat this process for every hole you need to drill, giving the hammer drill enough time to cool down between holes to prevent problems. 90005 90002 So long as you are careful and make accurate measurements, you’ll be amazed how simple it is to drill concrete when you have tools powerful enough to complete the job.90005 90014 Drilling Concrete is Easier Than You Think With the Right Tools 90015 90002 Do not let not knowing how to drill concrete prevent you from moving ahead with your construction process. By acquiring the right tools and following these steps, you’ll be amazed how smoothly the process will go. 90005 90002 We are thrilled with how simple the process was with our Mikita model hr2811F for installing all 38 concrete lag screws in our basement foundation, and we think this tool can work for you, too.90005 90002 90104 Did you enjoy this post?

Even if you have tried this before with little success, this should also be of some use. 90003 90002 Concrete brick, or mortar are tough materials and concrete is harder and tougher to get through than normal cement, mortar or brick.90003 90002 Before you even contemplate getting your drill out, I think it is a good idea to understand what you are up against. Below I have briefly explained the differences between brick, cement, mortar and concrete. 90003 90002 90009 What Is Brick Made From? 90010 90003 90002 Most bricks that we see everyday are made mostly from clay, which is the pressed into blocks, and heated up in a kiln to make them hard. 90003 90002 Other elements are added to them such as shale and hydrated silicates, some iron and sand.From a drilling perspective, they are usually fairly easy to drill through. They are used for building mainly and are easy broken as you may already know. 90003 90002 90017 90017 90003 90002 90009 What Is Cement? 90010 90003 90002 Cement is basically a fine mineral powder and when you add water it becomes a paste like substance that can act as a binding agent. 90003 90002 Depending on how cement is actually made it has different uses such as under water constructions, for setting posts and many other uses.This is relatively easy to drill through. 90003 90002 Almost always cement will have something added to it before it is used. In most cases that will be sand and water. it is then known as mortar. 90003 90002 90009 What Is Mortar? 90010 90003 90002 Mortar contains as its main ingredient cement and then has lime added, or may also use masonry cement and sand. It is mainly used for structural purposes such as binding bricks together in a wall. It is actually pretty easy to drill through, and much easier than brick.90003 90002 Because of that it does not make as strong a place to drill holes to attach something to. It will always be a better idea to drill the brick, if you are planning on mounting or hanging a heavy object. 90003 90002 90009 What Is Concrete? 90010 90003 90002 Concrete is a mixture of various aggregates like sand, gravel, crushed stone which are bonded together using cement. The older it gets the stronger it gets. Concrete will have about 15% of cement in it and most side walks, floors etc are made from concrete.90003 90002 This is the toughest of the four to get through. I will bet you are thrilled to hear that news, but worry not. 90003 90002 90047 90047 90003 90002 90009 TOP TIP 90010 90003 90054 90002 90056 If you are ever trying to attach something to a brick wall, then try to line it up so as the drill holes have to go through the mortar, rather than the brick as it is so much easier to drill through. Only do this though if you are hanging something light. 90057 90003 90059 90060 90061 90061 90063 90060 What Do You Need To Drill Through Concrete? 90063 90002 You need only two things: 90003 90002 If you have these, then it is just the technique that you will have to master and it is a lot easier than you may think.Before we look at the technique it is important to have the right tools at hand. 90003 90002 90009 The Best Type of Drill For Getting Through Concrete 90010 90003 90002 Ideally your drill should have: 90003 90076 90077 A hammer function 90078 90077 Variable Speed ​​90078 90077 Good grip and ideally a side handle for added strength 90078 90077 Strong and powerful 90078 90077 A depth setting is really useful 90078 90087 90002 If you have not got one then here is one that I would recommend.If you do not want to spend the money buying one, then rental or borrowing one will be your only option. 90003 90002 I do remember borrowing one from my father in law, when I did not have many tools, and yes I managed to wreck it. Thankfully it was my first lesson of many on my journey as a tradesman. A good hammer drill is not that expensive and will be a sound investment for the years to come. 90003 90092 How to Drill Into Concrete With A Regular (Non Hammer) Drill? 90093 90002 This is not an easy thing to do, but it can still be done.In the ideal world you would want to use a hammer drill, but if you have a regular drill, then the only thing you can do is make sure to have the right drill bits attached to the chuck. 90003 90002 The only thing that will get through concrete is a good quality masonry bit. Now without the hammer action the only thing you have working for you is the turning speed of the drill itself. 90003 90002 Make sure you have some water available and use that regularly to stop the bit from heating up. That way you will preserve the life of the bit.90003 90002 Avoid trying to thump the drill up and down into the hole though as that will damage the chuck on your drill. It will take longer to do it this way but that is the price you have to pay. Also remove the drill from the hole on a regular basis to allow the dust to be removed and also keep the flutes of the drill clear. 90003 90002 This will be a very slow and frustrating process. A hammer drill does this very quickly as not only do you have the spining action of the drill bit, but you also have the hammer action.90003 90002 90009 The Best Type of Drill Bits For Getting Through Concrete 90010 90003 90002 The only type of drill bits that will get through concrete are called masonry bits. These are specifically designed to be able to deal with this tough job. The main part of this drill bit is made from steel. 90003 90002 However the tip will have a tungsten carbide brazed into the tip to provide the tough cutting edge that is required. They are almost always used in conjunction with the hammer drill.90003 90002 When connected to the drill, this hardened head then continually bumps against the concrete and breaks it down, and the flutes of the drill bit will push the masonry dust out and away from the hole. 90003 90002 In terms of size you can get them anything between 5 mm to 40 mm in diameter and up to about 39 “in length. Here are the ones that I would recommend. You can find those by clicking here. 90003 90002 The bottom line here really is that you should never buy cheap drill bits to do any job, as they will drive you crazy.90117 90003 90002 90120 90121 90003 90092 Mastering the Drilling Technique For Drilling Floors, Blocks or Slabs 90093 90002 You need to figure out what size of hole that you need to drill and what depth you need it to be. If you are attaching something to a wall, then in most cases, the wall plugs should come with it. The most common sizes for these are either 10 mm or 12 mm. 90003 90002 In terms of depth, the simplest way is to set the drill head beside the wall plug and measure it.If there is s depth gauge on your drill, then set that. If not just use a piece of tape to measure the depth as shown in the picture below. 90003 90002 Now attach the drill bit into the chuck and tighten. 90003 90002 Mark the spot on the wall where you need to drill. I usually use a marker or make a dent with an old screwdriver. I actually keep an old screwdriver in my toolbox just for using on jobs like this. 90003 90002 You can use it to mark the hole and also to grind out a bit of the concrete, to help give you somewhere to place the point of the drill bit.90003 90002 Now place the drill bit on the marked spot and start drilling at a low speed. The secret here is applying the right amount of pressure. That comes with practise. It needs to be firm enough to avoid slipping and tight enough to allow the drill to rotate at a slow speed. Go easy at the beginning until the hole starts and then you can apply more pressure. 90003 90002 Once you get the hole started, then turn up the speed and let the drill do the work. This is a tough drill so it may take some time.The more powerful the drill you have and the better quality your masonry bits, then the easier this becomes. Stop, when you have reached the required depth. 90003 90002 Check out this video below to see a practical demonstration. 90003 90141 90121 So as you can see from the video above, if you have the right tools for the job, then drilling through concrete is a great deal easier than you may have thought. 90002 It depends a lot on what you are drilling the concrete for, as to what size of hole you need to drill, and what type of anchor or plug you are going to put into it.90003 90002 The bottom line is however, that as long as you have a good hammer drill, a decent quality masonry bit, then all it needs is a little know how and you can get the job done quickly and successfully. 90003 90002 You can click here to read reviews on the best masonry bits available right now. 90003 90002 Hopefully that has given you enough information, on how to drill through masonry of various types. 90003 .
