This bit is engineered to deliver consistent performance when you’re drilling deep into concrete or masonry. The SDS-Plus shank locks securely into compatible rotary hammers, maximizing impact efficiency and minimizing bit wander. The 12-inch overall length (with a 10-inch flute) gives you the reach you need for deeper holes and through-walls work, reducing the need to switch bits mid-project.
Ideal for professional installers and DIY enthusiasts tackling anchor installations, conduit runs, or electrical box openings in concrete walls and slabs. When paired with a suitable rotary hammer, you’ll notice cleaner holes with faster material removal and steadier progress—even on reinforced masonry.
Practical tips for best results:
- Keep the drill steady and apply consistent, moderate pressure to maximize bit life and hole accuracy.
- Pause occasionally to clear debris and prevent overheating—especially on deeper holes.
- Use proper safety gear: eye protection, gloves, and a dust mask for indoor jobs.
- Follow the tool manufacturer’s recommendations for rotating speed and hammer action to extend the bit’s life.
