FAQs
Can I use these bits with a standard drill driver?
No, these are SDS-plus bits designed exclusively for use with SDS-plus rotary hammer drills.
What sizes are included in the T3121 set?
The set includes 5x110mm, 6x110mm, 8x110mm, 6x150mm, 8x150mm, 10x150mm, and 12x150mm.
Are these bits suitable for drilling through metal?
No, these bits are specifically optimized for masonry, concrete, and stone. Using them on metal will cause rapid damage to the carbide tip.
Why do the tips look different from standard drill bits?
The tungsten carbide tips are vacuum brazed onto the head to withstand the high-impact forces generated by rotary hammer drills.
How should I store these bits to maintain their edge?
Always store them in the provided case to protect the carbide tips from impact damage and to prevent rust.
Troubleshooting
Bit becomes stuck in the wall during drilling
Ensure you are pulling the drill back periodically while running to allow the flutes to clear accumulated dust.
Excessive heat build-up
Reduce the feed pressure and ensure the drill is in hammer mode; check that the flutes are not clogged with debris.
Bit wobbles or does not sit securely
Check the SDS-plus chuck for debris; ensure the shank is pushed fully into the chuck mechanism until it locks.
Pros and Cons
Pros
- High durability thanks to vacuum brazed carbide tips
- Excellent dust extraction efficiency
- Secure SDS-plus shank connection
- Comprehensive selection of common masonry diameters
Cons
- Only compatible with SDS-plus drill chucks
- Not suitable for standard drill drivers without an adapter
- Limited to masonry and concrete applications
Setup, Compatibility & Care
To use the T3121 set, insert the SDS-plus shank directly into your rotary hammer drill’s chuck until it clicks into place. Ensure your drill is set to 'hammer' or 'rotary hammer' mode for the best results in stone or concrete.
Care instructions:
- After each use, wipe the bit clean of masonry dust with a dry cloth.
- Periodically inspect the tungsten carbide tip for chips or excessive wear.
- Store the bits in their case to prevent the carbide tips from striking one another, which can cause chipping.
- Apply a small amount of grease to the shank periodically to ensure smooth operation within the drill chuck.
