Different Types of Drill Bits

Different types of Drill Bits are required to drill suitable hole in any material. For basic requirements, a set of high-speed steel twist drills and some masonry bits will probably be sufficient for the average handyman. But for more sophisticated jobs/material, others bits will be required - perhaps larger, or designed for a specific material/purpose.

Different kinds of Drill Bits available for varied tasks are:

Twist bits: used on timber, metal, plastics and similar materials.

Screwdriver bit drills: designed for rechargeable screwdriver are used to drill pilot holes.

Masonry bit: are for drilling into brick, block, stone, quarry tiles or concrete.

Spur point bit: have a central point and two raised spurs that help keep the bit drilling straight that helps cut timber and some plastics.

Bullet Pilot Point: with their central point and two spurs can be used in metal, wood and plastics.

Countersink: is used to form the conical recess for the heads of countersunk screws. These bits tend to be designed for use on soft materials such as timber and plastics, not metals.

Countersink with clearance drill: is used for drilling clearance hole and countersinks it all in one stroke

Tile Bit: for drilling ceramic tiles and glass, it has a ground tungsten carbide tip.

Flat wood bit: are ideal where the head of a screw/bolt needs to be recessed into the timber.

Hole saw: used for cutting large, fixed, diameter holes in wood or plastic.

Combination hole saw: can cut large holes as it consists of a number of different sized round saw blades.

Forstner bit: used to form holes with a flat bottom, such as for kitchen cupboard hinges.

Wood Auger bit: ideal for drilling large-diameter, deep holes in wood or thick man-made boards.
