Our fastest, most accurate sharpeners for shops that restore bits weekly. With a more powerful motor than our standard bit sharpeners, they typically finish bits in less than a minute—even the biggest sizes. They also grip bits with more stability to sharpen within a tighter tolerance, so bits cut cleaner and last longer. Since the included chuck holds all compatible drill bit sizes, there’s no need to swap collets. To sharpen carbide bits, use the diamond wheel (sold separately).
