FAQ's

Q. What is the difference between a Cone Cutter and Step Drill Bit?

A. A cone cutter is a smooth sided bit that can make any sized hole, on a variety of materials.
A step cutter has parallel measurements up the cone, gradually getting bigger. These are great if you need to cut sized holes with reasonable accuracy. These bits are also capable of cutting through various materials.
