These reversible assemblies have a shaft and two cutters that will cut either a rail or a matching stile, depending upon their configuration. Used in combination with a raised panel bit, they can produce a complete molded and panelled door.

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.

For better safety, these bits should be used only in a router table equipped with a fence and not used free hand.

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

They use a 22mm × 8mm replacement ball bearing (available separately).
