Cutting Tool Blanks

WWSA’s PCBN is offered in two styles:

  1. WBNC which is carbide supported.
  2. WBNS which is a solid PCBN.

Both PCBN styles offer grades to cover a wide variety of hardened steels, super alloy, sintered powdered metals and grey and hard iron machining applications. The WBNC product line is comprised of a polycrystalline CBN layer supported by a cemented tungsten carbide substrate bonded together as a single blank by HPHT process. WBNS is our solid PCBN that is offered in several grades and shaped geometries that are second to none.

WBNC

WBNS

WPCD is a highly engineered polycrystalline diamond product.

It has been continually developed to offer excellent diamond to diamond bonding. This maximizes product performance across a wide variety of grades and allows targeting specific applications.

WPCD is produced with finely graded synthetic diamond crystals bonded to a tungsten carbide support layer. Where needed, WPCD offers a tight diamond particle size distribution (PSD) as well as our “S” style, which offers is a multi-modal product. The “S” style is a unique combination of finely graded particles with medium to coarse particles giving the product a fine finish while offering a longer tool life.
