Frequently Asked Questions
What is the 25.40 mm mortising bit used for?
The 25.40 mm bit is specifically for mortise locks and armored door mechanisms. Mortising (or oscillating drilling) works with lateral oscillating movement instead of standard rotation — it creates precisely dimensioned rectangular recesses for inserting locks, hinges, and mechanisms, without the need for manual chiseling. The bit size must exactly match the size of the lock box to be installed.
What machine is this bit used with?
Bernardo mortising bits are compatible with Bernardo benchtop mortising machines (HW series and others) and oscillating pillar mortisers. They cannot be used on standard drill presses — they require the specific oscillating movement of the mortiser. Please verify compatibility with your device before purchasing. Customer service in Italian available.
