This depth stop set from wolfcraft is the perfect addition to the mobile drilling aid (art. no. 4686000) for precise drill holes at the preset drilling depth. The set contains 3 depth stops in Ø 8, 10 and 12 mm, which are compatible with commercially available drill bits in the appropriate diameter and Forstner or cylinder drill bits with 8, 10 or 12 mm shank diameter. Mounting on the drill bit is quick and easy. Once you have adjusted the drilling depth, the drill delivers depth-limited holes in series.
