Draper Drill Grinding Attachment

The Draper Drill Grinding Attachment is a precision sharpening tool designed to restore HSS twist drills using a standard bench grinder. Suitable for workshop and maintenance environments, this attachment enables fast and accurate resharpening of drill bits ranging from 3mm to 19mm (1/8" to 3/4") diameter, extending tool life and maintaining cutting performance. The diecast body features pre-set notches at five different angles - 41° for countersinking, plus 49°, 59°, 68° and 88° - covering the most common tip angle requirements for general drilling applications. This eliminates guesswork and ensures consistent results when resharpening worn or damaged drill bits. Ideal for workshops, maintenance departments and trade professionals who regularly work with HSS twist drills, this attachment provides a cost-effective alternative to replacing drill bits. The precise angle settings make it straightforward to restore cutting edges to factory specifications, maintaining drilling accuracy and reducing downtime.
