Professional-grade twist drill bit engineered from high-speed steel (HSS) for versatile drilling applications. The 12mm diameter size handles a wide range of materials including steel, cast iron, aluminum, and wood with precision and durability. HSS construction resists heat buildup during extended use, maintaining sharp cutting edges longer than standard bits. Ideal for metalworking, fabrication, construction, and general workshop tasks. Suitable for use in hand drills, bench drills, and CNC machines. Essential addition to any builder's or tradesperson's tool kit for reliable performance on demanding jobs.
