Product Details
✓MAX 700 Holes: Under optimal conditions with proper cooling, this tungsten carbide drill bit delivers outstanding performance on CNC machines. Suitable for carbon steel, tool steel, cast iron, aluminum, stainless steel, and hot working steel < HRC40. Depending on material hardness, it can drill up to 400–700 holes
✓For CNC Machines & Drill Presses Only: Carbide is extremely hard but brittle, making it unsuitable for handheld drills due to vibration and movement. Designed for high-speed CNC machines and stable drill presses for maximum precision and durability
✓Enhanced Tip for Hard Materials: The 135° split point is ideal for drilling stainless steel, hot-working steel under HRC40, and other hard metals. Its reinforced geometry reduces cutting force, minimizes walking, and improves drilling accuracy and tool life
✓TiAlSi Coating for Stainless & Hard Steels: Advanced TiAlSi coating delivers higher hardness (3200 HV) and heat resistance up to 1300°C compared to standard AlTiN coatings. Built to handle extreme heat and wear when drilling stainless steel and other high-hardness metals.
✓1/4 Inch High-Precision Carbide Drill Bit: Includes 1/4" bits, perfect for delicate, precise drilling. Solid carbide construction ensures rigidity and maintains tight tolerances within ±0.003 mm
