Amana DRB-421 Straight Plunge Down-Shear Polycrystalline Diamond (PCD) Tipped 1/4 Dia x 12.32mm (1/2) x 1/4 Shank Single Flute Router Bit

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 double flute straight plunge router bits will groove and joint 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.
