Ideal when worn tips are causing wandering, overheating, or slow progress. Wide size compatibility: Works with drill bits from 2 mm to 13 mm, covering most common twist bit sizes used in woodworking, metalworking, and general home repairs. This single attachment handles multiple bit diameters so you don’t need separate sharpeners for each size. Power-drill attachment design: Designed to mount on a power drill, the grinding attachment uses the drill’s rotation for fast, consistent sharpening. It turns worn bits back into ready-to-use tools without complex setup. Durable construction: Crafted from high-quality materials to deliver long-lasting performance and reliable results project after project. Built to withstand regular use so your bits stay sharp and productive. Practical benefits: Extends the life of drill bits, reduces downtime replacing bits, and improves drilling accuracy and speed. A cost-effective way to maintain tool performance in a home workshop or on the job site. Typical applications Woodworking: Re-sharpen twist bits before cabinet, furniture, or trim work to ensure clean entry and reduced splintering. Metal and fabrication: Restore bits used on light gauge metals and sheet metal to improve bite and reduce heat build-up. Home repairs and DIY: Keep a set of bits sharp for general repairs, installing fixtures, or drilling pilot holes—no need to stop work to replace dull bits.
