You cannot assume all drill bits were created identical. Drill bits have been made for specific applications. Some are meant for drilling through timber, others are drill bits for masonry, still others are effective at drilling through aluminum and other metals. For this reason it is important that you employ the correct drill bit for the job, not just the very first one that comes to hand.
Drill bits for masonry are a variation on the twisted drill bit. Which means that the drill bit seems as if a piece of metal was held between two vice grips while one vice was held immobile and the other ended up being turned in an anti clockwise direction. The twisted look would be to help the drill bit to get rid of the debris it’ll produce when it is drilling.
The drill bit is created primarily form soft steel and is made on a mill, not ground just like other drill bits. The cutting edge of drill bits for masonry is made of a tungsten carbide insert that’s brazed into the steel.
Drill bits for masonry are generally used in conjunction with a hammer drill. This kind of drill will cause the actual drill bit to both turn and hammer into the work surface that you want the hole to be in. The tip of drill bits for masonry are rather blunt which allows them to break up the actual masonry when preparing for the cutting edge of the shaft of your drill bit. As the point of your drill bit is actually hammered in to the work surface the actual drill bit is turned which brings the cutting edge in to contact with another part of masonry which needs to be drilled through. The actual rotation also enables the actual flutes which are produced by the twisted form of the drill bit to remove dust and other dirt created by the drilling process.
Drill bits for masonry are normally available in diameters which range from 5 to 40 millimetres. If you need a hole that is larger in diameter than that you’ll probably be required to make use of a core bit instead.
The place you might usually use drill bits for masonry is if you have to set up cabling or plumbing. The actual drill bits should be able to drill in to the wall and you will then bring the wiring or plumbing out through the hole without the need to repair half the wall round the brand new cabling or pipes. It is possible to use drill bits for masonry which are up to 1 metre long on most hand powered tools which makes things much easier with regard to interior work.
As you can see drill bits for masonry are extremely specialised and will most likely not stand up to use on materials apart from masonry. It is because the soft steel they’re made form is going to be likely to warp if the drill bit is actually hammered in to a substance such as wood or even some type of metal. It’s really a much better idea to utilize drill bits that have been designed for the job at hand.
