Leigh does not sell metric bits

Inch Joints
Leigh offers a complete selection of router bits and joint guides for use on FMT jigs. Rout 68 sizes of "standard" inch joints using all 21 guides, and one or two bits. Limitless "custom" joint sizes up to 1/2" x 5" can also be achieved.

 

Metric Joints
Leigh offers a complete selection of joint guides and inch router bits for use on FMT jigs. Rout 79 sizes of "standard" metric joints using all 24 metric guides, and one or two bits. Limitless "custom" joint sizes up to 12 x 130mm can also be achieved. NOTE: Leigh does not offer metric bits — typically they can be found outside North America.
 


Router Bits

High Quality Bits
Spiral upcut bits are used with FMT jigs. They rout cleaner, faster and leave a smoother finish than straight bits. Both Solid Carbide and the less expensive High Speed Steel bits can be used on FMT jigs to produce excellent results, however Solid Carbide bits are stiffer and hold their edge longer. Leigh two flute spiral upcut bits are made in America.
 
Shank Size
All bits with a cutting diameter greater than 1/4"(6.35mm) are made with 1/2"(12.7mm) shanks. The extra stiffness reduces vibration and
chatter. The 1/4"(6.35mm) louver bit also has a 1/2"(12.7mm) shank because of the added forces with cross grain routing. Bits with a cutting diameter of 1/4"(6.35mm) or less have 1/4"(6.35mm) shanks.
 
Mortise & Tenon Bit Selection
Each spiral upcut bit has a maximum cutting depth. As the bit diameter increases, the maximum depth of cut also increases. Solid carbide bits generally allow a greater depth of cut. Choose a guide and bit combination to match the required depth.
