ISO 9001 Tungsten Mining Carbide Rock Drill Bits Hex 25mm

High quality tungsten carbide hard rock drilling bits for mining and tunnel drilling

1 Product description of Rock Drilling Bits

We use our 45CrNiMoVA materials production of tungsten carbide and YK05 cone drill bit, both of which are world famous drill bit production materials.

Advanced technology - we produce circular cone bit hot technology, which is currently producing circular cone drill the most advanced technology.
When the magnetic permeability decline carbide or signs of damage, should be re-grinding button drill
Fixed grinding program will usually bring good working practices.

For example, check bits, then shift end mill or milling again after a number of holes. Premature grinding is not necessarily uneconomical, because there are fewer hard alloys that need to be worn. It is best to re-grind, it will not damage and reduce productivity.

Correct grinding greatly increases the service life of the drill bit. But equally important, it also improves the performance of the entire drilling operation, especially straightness of the hole.

The taper drill is the most commonly used taper drill, and its head diameter ranges from 48mm to 26mm. The fan-shaped skirt is hot-pressed with cemented carbide drills, and the tapered fan-shaped drills have good performance and long service life.
