Cobalt drill for welding spots single-end BS1897RNHSSCo5E

High-performance single-sided ground drills with a short helix and a point for drilling spot welds. These joints are found on cars, so these drills will be welcomed by coachbuilders. You place the drill in the center of the spot weld and start drilling, thanks to the small centering tip and two cutting edges with an angle of 180 degrees, the drill does not bend anywhere and drills an upper metal plate off.
