The Planet Lip and Spur drill bits are the preferred type of cutting tip for drilling wood thanks to a steeper helix angle than standard drill bits. They also have deeper flutes for rapid clearance of waste. This enables the drill to cut quickly and cleanly. The brad point tip ensures straight and accurate drilling while the sharp spurs leave a clean edge by reducing grain tear-out. The appropriate sizes are suitable for use with doweling jigs. 12mm, Single: LSHSS12
