ADICO PCD is largely divided into coarse, medium and fine grades. By adjustment of the diamond and binder content ADICO developed 3 series (X, S, and U) to offer the perfect grade for your needs. The characteristics of each types are described in the table below.

Type "X" series "S" series "U" series

Microstructure and Characteristics
(available for all grades F, M, C)

 Increased metal binder phase for high mechanical impact resistance.

Little chipping and high grindability during production of PCD tools.

Shows good electrical conductivity, performs with superior cutting speed during EDM processing.		 High diamond content, for excellent abrasion resistance due to high hardness.

Reliable performance in a  wide application area. Even fine finish can be achieved in high silicon aluminum.		 This series is characterized by a maximized diamond content and an advanced diamond to diamond bonding.

Designed for highly abrasive applications and materials.

Laser Weldable PCD

An extra metal layer of PCD tungsten carbide substrate allows a new laser welding that brings lots of benefits over the conventional brazing for manufacturing PCD tipped blades.

Laser-Weldable-PCD

Product Offer:

  • Cut-pieces 3.2 mm (wire EDM cut)
Benefit:
  • Exceptionally high bond strength at the welding joint between PCD and tool body.
  • No risk of tool failure from unstable thermal stability related preblems.
  • Cost effectiveness from no brazing.
  • Offers both less health hazardous and cleaner environmental operation.

Application for Laser Welded PCD Tools:
  • Saw blades for cutting tiles, rocks, cement boards.
  • Saw blades for road grooving cement and asphalt.
  • Core bits for drilling rocks, bricks, ceramics, etc.
  • Others (like conventional PCD tools)
