Besly Combined Drills & Counterbores

These double end, combined drill and countersink center drills are used for centering the ends of work where the work is subsequently to be revolved on machine centers. The angle of the countersink part is made the standard 60 included angle to fit standard centers.

Available in plain type and bell type. On precision work, some users prefer the bell type, as the additional small 120 angular chamfer protects the edges of the center hole and reduces the danger of inaccuracies from marred center holes.

Please call 800 435-2965 for current net pricing.
