Hot Lee Valley Reversible French Door & Window Sash Bit

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 reversible French door & window sash has a body diameter of 1 3/8″, a depth of 1 3/4″ and a shank diameter of 1/2″.

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

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

Uses a 22mm × 8mm replacement bearing (available separately).
