Step Drills

Step Drills

We are a Manufacturer and Exporter of Step Drills in India, with different steps that cut the desired diameter. The Drills are used to do two works in a single pass and are designed to enlarge the hole as the drill bits through the sheet metal; each step on the bit is bigger in diameter than the step before. Step Drills can be easily re-sharpened or modified for a particular step length.

It’s like the shape of a cone. It allows you to make multiple sizes holes without the need to change bits. They are also used to enlarge a hole. DIC Drill Bits are exported to various countries worldwide. We provide you with standard and non-standard sizes per your workpiece requirement. The series comes in HSS and HSS-Co Variants. Each drill is made from industrial-grade steel and heat treated to provide maximum strength to the tools.
