PCD Step Drills

A PCD Step Drill is a high-efficiency precision cutting tool that combines polycrystalline diamond (PCD) cutting edges with a stepped tool body design. The tool body is composed of multiple coaxial cylindrical steps with increasing diameters, allowing drilling, hole enlarging, and chamfering to be completed in a single operation.

By integrating several machining processes into one tool, Sundi’s PCD step drill delivers long tool life, high machining accuracy, and significant savings in machining time and labor cost, making it ideal for high-precision drilling of non-ferrous metals and composite materials.
