Tungsten Carbide Drill Bit Set | HRC65 Super Hard | 0.5-20mm for Stainless Steel & Metal

Engineered for extreme hardness, the LUFEICNC HRC65° Tungsten Carbide Drill Bits deliver superior performance in stainless steel and hardened alloys. With a Rockwell hardness rating of 65, these bits maintain a sharp cutting edge far longer than standard HSS, reducing tool changes and increasing productivity on demanding metalworking projects. Features and Benefits - HRC65° Tungsten Carbide Tip - Exceptional wear resistance for drilling through hardened steel, stainless steel, and cast iron with minimal heat buildup and extended tool life. - Precision Ground Flutes - Optimized chip evacuation reduces clogging and heat, ensuring cleaner holes and preventing work-hardening of materials like 304/316 stainless. - 135° Self-Centering Point Geometry - Provides accurate starting without walking, reducing burrs and improving hole placement accuracy for CNC and manual drilling. - Full Size Range (0.5-20mm) - A comprehensive set for intricate precision work up to heavy-duty drilling, offering versatility for various project requirements. - Robust Shank Design - Ensures maximum grip and minimal runout in chucks, enhancing stability and drilling accuracy on lathes, mills, and drill presses. Applications - CNC Machining and Lathe Work - Ideal for automated production runs where consistent performance and minimal tool deflection are critical for tight-tolerance parts. - Professional Fabrication and Repair Shops - Tackle tough materials daily, from stainless steel fixtures to hardened tooling, with reliable, budget-friendly professional tools. - Automotive and Aerospace Metalworking - Drill high-strength alloys and stainless components with confidence, benefiting from the enhanced durability of tungsten carbide. - Advanced DIY and Prototyping - An excellent choice for enthusiasts and machinists who require quality tooling for challenging materials without the premium brand price point. Note For optimal results, use with a rigid setup, appropriate cutting speeds, and consistent coolant or lubricant, especially when drilling stainless steels.
