Lee Valley T-Slot Router Bits

This bit cuts a slot to fit our T-slot nuts. Slots are useful for making adjustable jigs and fixtures. Minor diameter is 5/16”.

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.

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