Product Description

3mm 4mm 5mm Carbide Drill Bit For Metal Steel High Hardness Co 11 Percent


tungsten carbide drill bits




During use, these carbide bits are attached to a power drill to generate torque and create the perfect sized hole for whatever the purpose may be. One of the more specialized uses for tungsten bits is PCB manufacturing. Because the drilling requires holes with diameters less than one millimeter, solid carbide bits are used to fit into these holes.
Though tungsten is quite durable, it can be expensive brand new. Luckily, the majority of tungsten products have been recycled for industry use. Tungsten carbide scrap remains a hot commodity within the manufacturing industry because of its multitude of uses and its durability.
