This drill depth stop is used to drill blind holes with Forstner bits, where exactly the same drilling depth is required. The ball bearing of the depth stop prevents the surface to be processed from being scratched. For materials to be processed and speeds to be used, see information on Forstner bits.
Ball-bearing depth stop made of wear-resistant plastic with replaceable guide bushes made of steel. Depending on the diameter of the Forstner bit centre shank, the corresponding replaceable guide bush can be mounted. The guide bush can be turned around in the depth stop to be able to achieve larger drilling depth with the Forstner bit.
