⚠️ Important Usage Notes

 

1. Start your hole at a 45-degree angle to establish an initial crescent groove, then slowly straighten the drill upright to prevent the bit from walking across smooth tiles.

2. Use moderate drill speeds without hammer mode, and apply water cooling during continuous passes on hard porcelain or granite to maximize diamond tip lifespan.
