FAQ
Q: What are 38mm and 50mm best for?
A: 38mm – switch boxes, faucet holes, vanity lights. 50mm – drain pipes, vent pipes, large cable pass-throughs.
Q: Does the free adapter fit all drills?
A: The adapter has a standard cylindrical shank (6mm or 8mm) that fits most drill chucks and angle grinders.
Q: Will this chip hard porcelain tile?
A: Use wet drilling + low speed + light pressure + the guide pin. This minimizes chipping significantly.
Q: Why does my bit feel stuck / not cutting?
A: Common causes: speed too high, no water cooling, or pushing too hard. Reduce speed and add water.
Q: Can I sharpen a dull bit?
A: Lightly drill into a scrap tile or soft brick a few times to expose fresh diamond.
