Fischer 551346 Glass drill bit Hex shank 1 pc(s)

This drill bit set is designed to abrade openings through brittle materials by means of a diamondised cutting surface mounted as a hole saw. Operated with a powered drill and the hex shank engaged, the bit is advanced at moderate speed with light feed to allow the abrasive segment to cut the glass, tiles or ceramics without exerting excessive radial stress. The working length accommodates controlled drilling depths while the overall tool length provides reach for common installation tasks. Typical uses include creating precise small-diameter holes for fittings or feed-throughs where minimising substrate damage is essential; coolant or intermittent withdrawal is recommended to help remove debris and maintain cutting action.
