Step Drill Bits

Step drills are an efficient way of drilling multiple sized holes in a piece of work without the need to frequently change bit sizes. Their stepped cone shape allows for multiple diameter cutting surfaces on one drill bit along a short distance. This construction helps to produce cleaner holes as the bit cuts incrementally larger holes as it passes through the material. This method stops the need to switch between multiple drill bit sizes when working from a small pilot hole up through to holes 40mm or more.

Features and Benefits
• Time saving
• Multiple hole sizes from one bit
• Cleaner cut holes
Where might I use one?
Step drills are suitable for materials such as metal, wood and acrylic and can be used in both hand and pillar drills. Always consider the materials you are working with when purchasing a stepped drill bit due to their shortened length when compared to traditional twist drill bits.
