Product Overview

Description



 


Our step drill bit is very solid, and the hex shank on the end has a solid connection and good fit in your drill. I checked these with a calipers and the sizing is accurate. The size of each step is stamped in to the side of the bit, which is a nice feature!


When you use it to drill a hole in a plastic part to install a button, and the sharp edges cut into the plastic like butter. Left a really clean even opening with smooth edges all around and perfect fit.
