Built from 4241 high-speed steel (HSS) and finished with a nitriding black surface treatment, this bit is designed for hardness, wear resistance, and improved corrosion resistance during everyday use. The 118° point angle is a general-purpose geometry that helps the bit start and drill efficiently in both wood and common metals.
Best uses: wood, plastic, and medium-hardness materials such as copper, aluminum, and iron. For best results, keep the drill perpendicular (90°) to the workpiece and drill a small guide hole first when stepping up to larger holes. Note: this bit is unsuitable for stainless steel.
