What people love

What people don’t love
- Durability is limited; tips burn out quickly after about 15 holes.
- Not suitable for concrete; bits may wear out very fast in harder materials.
- Bits can slip if not properly indented before drilling.
- Some users feel the price is slightly high for the quality and longevity offered.
- Bits tend to “walk” a bit during use, even when precautions like blue tape are applied.
