This precision step drill bit is purpose-built for knife and gun makers who demand accuracy and clean results when seating handle fasteners. Featuring a two-step design (.156 inch pilot x .312 inch head), this bit is ideal for setting Loveless-style bolts and similar fasteners with tight tolerances. Each bit is machined from high-speed steel (HSS) to exacting specifications, ensuring consistent hole dimensions and smooth cuts.
The brad-point tip provides exact starting accuracy, helping to reduce drift and guarantee pinpoint hole placement. While not intended for drilling steel or metal, this step drill performs exceptionally well in composite and traditional handle materials such as wood, bone, G10, carbon fiber, and resin-based synthetics. Whether you're customizing a blade, assembling a holster, or crafting in fine woodwork, this tool delivers clean, professional results every time.
