CNC POLYCRYSTALINE DIAMOND router bits, from Amana Tool, are specially designed for abrasive materials such as particleboard, MDF, veneer, hardwood, plywood and melamine.

The cutting edge lasts up to 100 times longer than standard carbide, making the bits an economical choice for industrial projects, according to the company. To help extend tool life, the bits can be resharpened without sacrificing profile dimensions. They feature up/down shear action for cutting double-sided material, as well as a solid carbide plunge point. The bits start at $143.96. For information, visit www.amanatool.com.
