The candle-shaped carbide tip and blade edge are thinned, making it possible to drill the material sharp, and the drill speed is improved. The center point of the carbide tip provides excellent positioning performance, and allows for a close hole in a true circle. The center point prevents the core from shaking during drilling and reduces vibration burden while working. Package size: 1.0 inches (25 mm) Width: 10 mm). Package weight: 2.2 oz (7 oz (72.0 g).
