Fischer 551350 Glass drill bit Hex shank 1 pc(s)

This glass drill bit is designed to create circular holes in brittle surfaces using an abrasive cutting face bonded to the tool tip. When operated with steady speed and light axial pressure, the diamond grit abrades material rather than chipping, allowing progressive penetration through glazed and unglazed substrates. The hexagonal shank connects to common cordless or bench drivers, ensuring rotational stability while the saw-style flank removes the worked material. Typical use includes on-site installation of fixtures and fittings where clean, accurately positioned apertures through tiles, glass panes or ceramic panels are required; coolants or intermittent breaks in cutting preserve bit life and minimise thermal stress in the workpiece.
