Tungsten Carbide Drill Bit Set | HRC65 Hardness | For CNC & Lathe Steel Drilling | 0.5-20.0mm

Engineered for demanding metalworking, these TOOLEYE HRC65° Tungsten Carbide Drill Bits deliver exceptional durability and precision. The ultra-hard carbide construction and 135-degree split point design ensure clean entry, reduced walking, and extended tool life when drilling super-hard steels and alloys up to 65 HRC. Features and Benefits - HRC65° Tungsten Carbide Tip - Provides superior wear resistance and heat tolerance for drilling hardened steels, stainless steel, and cast iron without rapid dulling. - 135-Degree Self-Centering Split Point - Minimizes bit walking for accurate hole placement and reduces the thrust force required to start the cut. - Full Size Range (0.5-20.0mm) - Offers a comprehensive selection for precise hole diameters in detailed CNC work or manual machining projects. - Precision Ground Flutes - Efficiently evacuate chips to prevent clogging, reduce heat buildup, and ensure smoother, faster drilling operations. - Robust Construction - Designed for the rigors of CNC lathe, milling machine, and high-RPM drill press use, providing reliable performance. Applications - CNC Machining and Lathe Work - Ideal for automated precision drilling in tool rooms and production environments requiring consistent, high-tolerance results. - Professional Fabrication and Repair - Drills through tough materials like stainless steel, alloy steel, and hardened tool steel for maintenance, automotive, and metal fabrication. - High-Precision Manual Drilling - The self-centering point and sharp cutting edges provide control and clean holes for machinists and advanced DIY enthusiasts using drill presses. Note For optimal performance and longevity, use with appropriate cutting fluid and secure workpiece clamping. Always operate within recommended speed and feed rates for your material.
