Stubby Straight Bit

Most 1/4" diameter bits have long flutes and are inherently weak. This single-flute bit will cut a 1/4" wide slot only 3/8" deep and is more robust than longer bits.

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 nonstick coating for easy resin removal.

Each bit includes a friction-fit holder that can be mounted horizontally or upright.
