Custom Carbide Step Drills for Distributor & OEM Orders

HY Cutting Tools reviews solid carbide step drill requirements for combined hole features. Distributor and OEM inquiries can be based on a finished-part drawing or a tool drawing identifying each diameter and axial position.

Specify step diameters, step lengths, included angles, tolerances, shank, coolant configuration and workpiece material. Quantity, sample approval, inspection scope, marking and packaging are confirmed with the approved tool specification.
