Champion DBK8 90° HSS Double-Ended Zero-Flute Countersink | 1/8" to 15/64" | 1/4" Shank — Weldon-Style Deburring Countersink
The DBK8 is a Champion 90° HSS double-ended zero-flute countersink sized for flat-head screws from 1/8" to 15/64". Its single cutting edge is designed for fast stock removal and a smooth, chatter-resistant finish when deburring drilled holes, breaking sharp edges or preparing seats for flat-head fasteners.
This exact DBK configuration has a 1/4" shank and 1-3/4" overall length. The double-ended format provides two usable cutting ends in one tool, while the zero-flute Weldon-style geometry supports controlled cutting in production, fabrication and maintenance work.

Consistent Countersinking
Match the cutter to the exact 1/8" to 15/64" screw range, secure the workpiece and establish the desired depth before cutting. Moderate RPM, light pressure and proper alignment help produce a clean 90° chamfer and extend tool life.
Cutting tools may shatter if misused. Wear appropriate PPE and follow the machine and tool manufacturer's instructions.
