Uxcell 4mm Dia 80mm Long Length Titanium Coated K35 Tungsten Carbide Twist Drill Bits

Made of super fine grain carbide it has high hardness (HRC92-94) wear resistance heat resistance and high bending strength. With good milling and cutting performance carbide can run at higher speed than high-speed steel. Suitable for drilling materials below HRC55 such as stainless steel alloy steel tool steel carbon steel aluminum alloy 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 drilling machines CNC lathes CNC engraving and milling machines. Adapt to several kinds of cooling conditions such as oil mist water oil air cooling. The longer the length of the tool clamped by the chuck the better. Tips: If the clamping length is shorter you need to lower the feed rate and cutting speed to reduce vibration and extend the tool life. 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.
