3mm To 12mm Drill Bit Sharpener

Engineered for compatibility with 125 mm angle grinders, this sharpener accommodates drill bits from 3 mm up to 12 mm in diameter. Constructed from a combination of metal and plastic, it balances strength, stability, and safe handling. The device clamps directly onto the grinder, guiding each bit into consistent contact with the abrasive disc to reproduce accurate point angles and lip clearances. Its layout allows positioning of more than one bit at a time, streamlining batch sharpening. No batteries or power supply required — operation relies entirely on the host grinder’s motion and user control. Suitable for resharpening standard twist drill bits used across home improvement, carpentry, metalworking, and maintenance applications.
