• [MATERIAL] - High speed steel(HSS) is high toughness and high hardness, and is not easy to break. The drill bit is sharp and is easy for chip removal.
• [APPLICABLE MATRRIALS] - Suitable for processing non-ferrous metals (such as copper and aluminum), non metallic and ferrous metals (such as iron, steel and stainless steel).
• [APPLICATION] - Wider using range (rough processing, finishing, semi finishing), and comes with edge clear function, make processing products have better surface finish.
• [NOTICE] - When drilling, it is necessary to add cutting fluid in time to lubricate and cool down, which can get a better drilling hole wall, extends the service life and drilling accuracy.

This product is made of high speed steel and cobalt material. After using full grinding process, it has stronger cutting ability and longer service life. Suitable for processing non-ferrous metals (such as copper and aluminum), non metallic and ferrous metals (such as iron, steel and stainless steel). Straight shank works in both keyed and key-less drill chucks. The advantages of full grinding drill bit:High geometric precision, strong cutting ability. Smooth surface finish, long service life. Wider using range (rough processing, finishing, semi finishing), and comes with edge clear function, make processing products have better surface finish.
