Tooleye HRC45 Carbide Drill Bit Metal Drill Bits Tungsten Steel Drills For CNC Lathe Machine Alloy Drilling Tools 05-200mm Tooleye HRC45 Carbide Drill Bit Metal Drill Bits Tungsten Steel Drills For CNC Lathe Machine Alloy Drilling Tools 0.5-20.0mm Product Information: Name: Twist Drill Bit Material: Carbide/Tungsten Steel Diameter: 0.5-20.0mm (increments 0.1mm) Processing Hardness: HRC45 Coating Type: Uncoated Application: Widely used for processing metal materials such as carbon steel, mold steel, alloy steel, tool steel, copper, aluminum, etc. Application Device: Precision CNC equipment such as CNC machining centers, CNC lathes, engraving machines, bench drills, etc. Product advantages: 1. The overall material is made of tungsten steel, which has very high seismic resistance and wear resistance. 2. Equipped with a large capacity spiral chip removal groove, the integrated spiral groove ensures smoother chip removal. 3. The cutting edge of the drill bit has a nano coating, which can quickly cut and drill holes, effectively reducing the number of tool changes. 4. Standard round and straight shank design, strong compatibility, tight bite, high bearing capacity, and not easy to break Notices: 1. Tungsten steel drill bits have very high hardness, but their relative toughness will decrease, and are not recommended for use on equipment with poor stability. For example, handheld devices. 2. The higher the HRC value, the higher the hardness and wear resistance of the metal material that can be processed; If you want to process materials such as aluminum and copper that are prone to knife sticking, it is recommended to use uncoated HRC45 drill bits. 3. The diameter of the drill bit is available in increments of 0.1mm from 0.5 to 20.0mm. If you cannot find the diameter you need, please contact customer service for assistance.
