Drill Bit Sharpener For 3mm To 12mm

This drill bit sharpener is compatible with 125mm angle grinders and designed for drill bits ranging from 3 mm to 12 mm (approximately 1/8 inch to 1/2 inch — note: original states 1/16 inch to 1/2 inch, but description consistently specifies 3–12 mm; we use the numerically precise and repeated metric range). It features a durable metal and plastic construction. The unit is engineered for secure attachment to standard 125 mm angle grinders, enabling consistent, repeatable sharpening. Its design supports simultaneous sharpening of multiple bits, reducing workflow interruption. The sharpener guides the bit to maintain correct geometry and cutting angles during grinding, helping restore effective cutting performance. Intended for both DIY users and tradespeople who regularly maintain HSS or carbon steel twist drill bits.
