Description
A finger joint is one of the strongest joints in woodworking. As it effectively triples the surface area of the glue joint, it is nearly indestructible.
This bit has five tapered slotting cutters and an abutting-edge cutter. These are stacked as necessary to finger joint material from 7/16" thick, where you would use the abutting edge and a single slotting cutter, up to material 1 3/8" thick, where you would use all six cutters.
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.
Instructions are included. The bit is 1 9/16" in diameter with a 1/2" shank. Depth of cut is 1/4". All cutters are carbide tipped.
The bit includes an advanced polymer friction-fit holder that can be mounted horizontally or upright.
