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.
These single-flute panel pilot bits have carbide-tipped ends for plunging through material.
Used to rout openings in the middle of panels, such as for sinks. Cut length is 3/4" for the 1/4" size, and 1" for the 1/2".
Each bit includes an advanced polymer friction-fit holder that can be mounted horizontally or upright.
