Masonry Drill Bits
Masonry drill bits are designed for drilling into block, brick, quarry tiles, stone or concrete. The cutting end is usually made from tungsten and is bonded to a steel shaft which is spiral in shape. Some masonry drills are “durium tipped” which means they are covered with a very durable silicon bronze alloy which us used in place of tungsten in the cutting end.
Masonry drills are mainly used in power drills, however they can also be used in a hand brace although it will require a lot of effort to do this! It is possible to use a hammer action power drill with the majority of masonary bits. However, the action puts a lot of stress on the bit and lesser quality bits tend to break when pounded but generally, masonry bits are usually used with a hammer drill.
The bit is turned in a circular motion whilst hammering into the material. The hammering action breaks apart the masonary at the tip of the drill bit and the indents in the body of the bit carry the dust away. With every hammering action, the rotation of the bit enables the cutting edges onto a new area of the hole’s base. Special shanks are often used with hammer drill bits.
Remember to constantly withdraw the bit to flush out the drilling debris and when drilling harder materials, make sure to always use a slow rotational speed otherwise the tip will overheat.
Masonry drill bits are usually available from 5mm to 40mm. Core bits are used for larger diameters. Hand portable power tools are used with drill bits up to 1000mm and they good for installing plumbing and wiring in established buildings.
Drill bits come in a range of shapes and sizes and it’s vital to use the appropriate drill bit for the task in hand. Not all bits do all jobs. Drills don’t normally come with bits, so you will need to purchase them separately.
If you are drilling masonry, you will require a masonry drill bit which are specially designed for boring into brittle and hard materials like concrete, stone and brick and are the only bits that a hammering action can be used with as they won’t shatter. It pulverizes the material being drilled and with a rotary motion, it brushes debris from the hole. When drilling into tiles however, the hammer action should not be used. The drill bit can become extremely hot when drilling masonry, so take care to avoid burns.
Take care to remove all the dust from the hole as it can get clogged in the drill bit, choking it which wastes the drill’s power and can lead to the drill bit breaking and getting stuck in the hole. To avoid this, especially when drilling downward holes, use a pumping action.
When debris from drilling clogs the hole, this can prevent the insertion of a wall plug. A trick is to use a bendy straw and blow the dust out taking care to close your eyes while blowing. Ask a helper to vacuum up the dust you blow out as you blow to make cleaning up easier. Another handy trick to ease cleaning up when drilling inside the home is to stick an envelope below your designated hole area before you drill to catch the dust.
There are several main companies that make and supply drill bits and accessories including Hilti, Irwin and Makita. Along with masonry drill bits, there are many other types on the market including step drill bits, flexible, tile drill bits, brad point, long and short bits, glass and metal.
