Descriptions:Made of fine-grained tungsten carbide, the drill bit has good toughness, high hardness (HRC92), wear resistance and heat resistance. With good cutting strength and drilling effect, carbide tool offers long tool life and faster cutting speeds than other substrates.
Widely used for drilling steel below HRC60, such as stainless steel, carbon steel, die steel, alloy steel. The AlTiSin composite coating has high hardness, high wear resistance and high thermal stability.
Large spiral flutes provide neat and smooth cuts. Spiral groove facilitates the export of metal chip, saving time and effort in operation. Universal chamfered round shank, easier clamping, stable cutting process.
Suitable for CNC machining centers, CNC machine tools, precision engraving machines and other equipment. 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. 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.
