Spade drill

Spade drill is a modular high performance replaceable insert drills launched by CHTOOLS. Spade drill can be used in traditional machine tools and CNC machine tools, directly insert replacement, no need regrinding, higher drilling speed and other characteristics can greatly improve the efficiency of drilling. Especially compared with twist drill, the efficiency has been greatly improved, and has become the best choice for traditional machine tools and CNC machine tools to improve the quality and efficiency of hole processing. Spade drill consists of tool holder and insert, and with a set of oil ring to realize the cooling system of the traditional machine tool from outer cooling to inner cooling. The tool holder made of high strength heat-resistant alloy steel after heat treatment and precision machining. The insert is made of powder metallurgy high speed steel and cemented carbide. Insert diameter range : 9.5 mm to 114 mm, can drilling respectively in steel, stainless steel, alloy steel, cast iron, steel, aluminum alloy materials etc.
