1. Not recommended for use with cordless drills or screwdrivers below 18V due to insufficient torque.

2. Use water cooling when drilling tiles, glass, or stone to reduce heat and prolong drill bit life.

3. When drilling walls, avoid steel reinforcement bars to prevent chipping; change drilling position if encountered.
