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.

How soon will I get my sharpened tools back?
