FAQs
What is PCD?
- PCD Polycrystalline Diamond is produced by sintering
together micron sized diamond particles at ultra-high pressure and
temperature in the presence of a metallic catalyst. The presence of
the metal in the PCD structure together with Tungsten carbide
substrate, confer a degree of toughness not found in a single
diamond product
Can You Sharpen PCD tooling?
- Yes - Using the same type of machines as other
manufacturers, we are able to sharpen tools to the same degree
of accuracy as when the tool was first made
What is TCT?
- Tungsten Carbide Tipped Tooling
- Monotungsten carbide, WC, or Ditungsten
Carbide, W2C, is a chemical compound
containing tungsten and carbon, similar to titanium carbide. Its extreme
hardness makes it useful in the manufacture of
cutting tools, abrasives and bearings, as a cheaper and more heat-resistant alternative
to diamond.
Where do you deliver?
- We Can arrange delivery almost any where. But we also have
our own dedicated fleet of delivery vans covering the
Midlands- Northwest-Northeast of England, other areas covered by
postal carriers, usually next day delivery.
