Straight Plunge Bits

Our professional/industrial grade bits have tungsten carbide inserts ground on CNC (Computer Numeric Control) machines using 600x diamond wheels. Tungsten carbide maintains its hardness at high temperatures and holds an edge far longer than high-carbon or high-speed steels. The bit bodies have a non-stick coating for easy resin removal.

The 3/8” straight plunge bits are suitable for use with our router letter template set.

A 1/2" to 3/8" split bushing adapter, to allow use of 3/8" diameter shaft bits in a 1/2" capacity router, is available separately.

Each bit includes an advanced polymer friction-fit holder that can be mounted horizontally or upright.
