Worst Masonry Drill Bits Ever.

As a result of using this product I found that it was completely ineffective when drilling INTO concrete... i had to keep replacing the bits after only a few uses, which was incredibly frustrating. The only positive was that they were relatively cheap. However, the quality was so poor that I ended up spending more in the long run on replacements. I would not recommend these to anyone in the Industrial and Scientific field..

Pros
  • Powerful and efficient for drilling through masonry quickly.
Cons
  • Heavy and may cause fatigue during prolonged use.

Good but will not drill through rebar

The bit was great for concrete but I bought it thinking it would go through both concrete and rebar (based on the description). It does NOT go through the rebar. Now I need to buy a separate rebar bit.

Pros
  • Optimized for cutting rebar at high speeds. High quality steel offers increased core strength, durability and bit life
Cons
  • Easily torn
