Step Drills - HSS

Create clean, accurate recessed holes for custom fasteners with these precision step drill bits engineered specifically for knife makers, gun makers, and precision craftsmen. Each bit is manufactured from high-speed steel (HSS) and turned to exact specifications to provide consistent dimensions, smooth cutting performance, and reliable results when installing specialized screws, bolts, and handle fasteners.

 

Designed for use with handle materials and composites, these step drills allow you to drill both the pilot hole and recessed head pocket in a single operation, producing a clean, professional fit for fasteners. The integrated brad-point tip provides a centered starting point that helps prevent wandering and improves hole placement accuracy—an essential feature when working on precision knife handles, firearm grips, holsters, sheaths, and specialty projects.

 

These step drills are optimized for materials such as wood, bone, carbon fiber, G10®, phenolic resin, KYDEX®, HOLSTEX®, Boltaron®, PVC, and other non-metal materials. They are not recommended for use on steel or metal applications. Whether you are installing Corby bolts, Loveless-style fasteners, socket head screws, button head screws, hidden bolts, or thermoplastic mounting hardware, these precision tools provide the accuracy needed for professional-quality craftsmanship.

 

Available in multiple sizes and configurations to match a wide range of fasteners, each model is designed around specific thread diameters, head diameters, and hardware requirements.
