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 ball 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.
