Tungsten Carbide Drill Bits

The tungsten carbide drill bits are specially used in core drilling, which cylindrical steel core drilling bits are covered by a layer of tungsten carbide. Threaded (screwed) connection core tube and water channel have been designed for it. The ordinary tungsten carbide bits are suitable for drilling strata (formation) from Ⅱ to Ⅶ grade, and needle-like tungsten carbide bits are quite appropriate for drilling rocks from Ⅵ to Ⅷ grade.

Features

1. Tungsten carbide drill bits can be used in drilling complex terms and high drilling velocity is always available.
2. The blades of core drilling bits are made of high-performance alloy, which can greatly reduce the possibility of blade collapsing, as well as ensure good wear resistance.
3. Multi-layer geometric cutting edge is designed to improve its discharging property, as well as to lower its cutting resistance.
