Choose an option to view item availability.
Ideal for template work, these combination trim and template bits minimize tear-out caused by cutting against the grain.
The double-bearing system lets you flip the template and workpiece to alternate which bearing is engaged to allow an entire profile to be cut with the grain. For flush cutting, either bearing can be used.
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.
Includes two bearings, a shaft collar and a hex key. Each bit also comes with an advanced polymer friction-fit holder that can be mounted horizontally or upright. An excellent system for template work.
Replacement bearings are available separately. The 1/2" diameter bit uses a 1/2” × 3/16” bearing and a 1/2” × 1/4” bearing; the 3/4” diameter bit uses two 3/4" × 1/2” diameter bearings.
This flush trim bit lets you flip the template and workpiece partway through the cut so the router always feeds with the grain, keeping both halves of the profile clean instead of tearing out on the cross-grain side.
Yes, either of the two bearings works alone for standard flush-cutting jobs, so the bit handles everyday trim work as well as two-sided template profiles.
The inserts are CNC-ground tungsten carbide, a material that resists losing hardness at the high temperatures generated during a cut, so it holds an edge longer than high-speed or high-carbon steel.
It's available with a 1/4" shank, a 1/2" shank or an 8mm shank, each sized to match the bit's cutting diameter.
Yes, replacement bearings are available separately, sized to match each bit diameter, so you don't need to replace the whole bit if a bearing wears.
