Carbide Drill Bit Benefits
The use of Tungsten Carbide in drill bits provides a longer
lasting, stable, and solid material for use in drilling within
numerous industries. Carbide recyclers process the scrap carbide
through their facilities and send this cleaned material out to
manufacturers who reform the carbide into new products such a
carbide drill bits.
Carbide drill bits can be either solid tungsten carbide or merely
have the tips covered in a Tungsten Carbide cement.These Carbide
drill bits are preferred in construction, mining, farming,
automotive and machine shop industries due to their long life. As
with any metal of drill bit, there is always wear and tear,
dulling, and sometimes breakage. Machine shops can resharpen
carbide drill bits in order to further lengthen their usage life.
The carbide scraps, filings and sludge can then be delivered to
carbide recyclers for the best current scrap carbide pricing.
Carbide-USA provides specific instructions on how to keep the
carbide scrap separate from other metals and how to properly
deliver to their offices.
The major benefit of carbide drill bits is that they provide a
longer working life due to their hardness factor. Hardened steel is
not able to last as long in steady applications as Tungsten
Carbide. By utilizing carbide material, industries can keep their
tools on line in the field for longer periods of time preventing
down time and loss of time spent on a project.
