Diamond is the hardest material on the earth. Polycrystalline Diamond (PCD) tooling is manufactured in a high-temperature and high-pressure laboratory that fuses diamond particles onto a carbide substrate, which allows the diamond to be brazed onto a tool body.

If you’re looking for the ultimate in tooling you’ve found it! Amana Tool®’s PCD tipped compression CNC router bits will groove joint rabbet and surface plane a wide variety of tough abrasive materials including composites, particleboard, MDF (both raw or with melamine), veneer and hardwoods. The cutting edge lasts much longer than carbide for extremely long life.

Perfect for:

  • Resurfacing spoilboards using CNC
  • Planing large glued up panels using CNC
  • Surfacing and finishing wood using timber slab machines
  • Rabbeting or slotting
Excellent for Cutting:
  • Aluminum Bronze & Copper
  • Aluminum Composites
  • Aluminum Composite Material (ACM)
  • Composites
  • MDF
  • Particle Board
  • Plywood Veneer
  • Wood
Benefits of Diamond Technology

  • Harder cutting edge provides higher resistance to wear
  • Cut thousands of feet more than carbide without changing tool saving setup time
  • Optimized machine tool efficiency
  • Quality of finish is often significantly improved


Use “Ramp Down” technique.
