Uxcell 2.65mm Dia 4mm Shank Titanium Coated Carbide Straight Shank Twist Drill Bit

Made of super fine grain carbide it has high hardness (HRC92) high strength and wear resistance. With good milling and cutting performance carbide can run at higher speed than high-speed steel. The passivation treatment greatly increases corrosion resistance and wear resistance. Suitable for drilling materials below HRC60 such as stainless steel alloy steel tool steel carbon steel etc.. Titanium nanometer coating provides excellent corrosion resistance greatly improves wear resistance and hardness and reduces the coefficient of friction. Large and spiral chip space design for fast and clean chip removal. Sharp cutting edge provides smooth cutting and no glitches. Suitable lubricant is conducive to cutting or cooling making cutting easier improving smoothness and dimensional accuracy. Used on machining centers CNC lathes CNC engraving and milling machine. The longer the length of the tool clamped by the chuck the better. If the clamping length is shorter you need to lower the feed rate and cutting speed to reduce vibration and extend the tool life. Tips: Combined with the material to be processed select an appropriate feed rate and cutting speed to improve the tool life and obtain better processing accuracy and performance.
