Multicut step drill 3/16in-7/8in

This Unibor 06X5E step drill creates hole sizes from 3/16 inch up to 7/8 inch in a single bit. The 3-flat shank prevents slipping in standard drill chucks. It suits maintenance crews, fabricators and DIY users who need multiple diameters without changing tools.

3-flat shank fit and step progression

The three flats on the shank lock securely into any 3-jaw chuck, so the bit will not spin under load. Each step increments the hole size, letting you drill pilot, clearance and final diameters in one pass. This reduces tool changes and keeps the workpiece clamped.

Heat and wear in normal drilling

Cutting edges are ground for clean chip removal, which limits heat build-up during typical metal and plastic work. Steady feed pressure and cutting fluid keep temperatures moderate and extend edge life. The design avoids aggressive grabbing, so vibration and noise stay low under normal use.
