Fischer 551348 Glass drill bit Hex shank 1 pc(s)

This glass drill bit is a specialised hole saw designed to remove material from brittle substrates using a diamond abrasive cutting face. During operation the diamond matrix abrades glass, ceramic and tile surfaces while coolant or intermittent feed reduces heat build-up and glazing of the cutting face. The tool is driven via a hex shank for positive transfer of torque from hand-held or bench-mounted drills, and users control feed rate and rotational speed to maintain cutting efficiency. Typical uses include creating clean holes for fittings or pipework through tiles, glass panels and ceramic fixtures in construction and installation environments, where precise, burr-free apertures are required.
