Description

Tungsten carbide drill bits, micro drills,solid tungsten carbide drill bits,small carbide drill bits

Cemented carbide has the advantages of high hardness, toughness and corrosion resistance can stand the annealing without changing its physical characters. So, cemented carbide is a very good material for drill bits, replace the HSS perfectly in function and tool service life, however price per piece is more expensive than HSS drill bits, usually applied for precision drilling in lathe tools, machining centers, automobile parts, molds, ceramics, woodworking, etc.
