Product Info
R18CO NAS907 type J jobber drills are available in wire gauge sizes from 80 to 1 and have a heavy duty design, recommended for use in difficult materials and applications. Manufactured from premium High Speed cobalt (HSCo) for drilling tool steels and other hard materials, they have a 135 degree split point to help with self-centering and reduce the force needed to drill the hole, whilst the bronze oxide finish prevents workpiece material from sticking to the surfaces of the drill, producing clean and accurate holes.
