There are many different kinds of drill bits for certain applications. Some bits are made for drilling into wood, concrete, brick, stone, stainless steel, metal, tile, glass, and more. Here we have the most common types and explain what each one is best used for. Knowing the different types and sizes of drill bits and what they are used for, can help any DIYer to complete a project faster.
Auger Drill Bits
Used for drilling into dry, hard wood.
The spiral auger effectively removes wood chips as you drill.
The screw head on the tip draws the bit into the wood eliminating the need for pushing.
Masonry Drill Bits
Used for drilling into stone, concrete, and brick.
This bit has a tungsten carbide tip that allows it to drill into these materials.
This type of bit should be used at the correct RPM to avoid melting the tip.
Step Drill Bit
Used for drilling into almost any surface (depending on thickness).
This bit is for drilling multiple sized holes in most surfaces.
It is meant to be used on thin and softer materials for enlarging holes and deburring.
Twist Drill Bits
Used for drilling into metal, wood, and plastics.
This is the most common type of drill bit and is meant for multiple uses.
This is the most common type of drill bit to use in a cordless drill.
Wood Drill Bits
Used for drilling into all types of wood.
Also called Brad point and W point, this bit is designed to not grab or snag.
The wide tip allows for entrance before the shaft which makes cleaner holes in wood and some plastic.
