When I tried this product for the first time it was like a dream come true .I needed an industrial and scientific drill bit for cutting concrete and this PRODUCT delivered. The diamond thread worked wonders and I could cut through the concrete with ease. The only downside is that it's a bit pricey, but you pay for the quality. Overall, I highly recommend this cutting tool for any industrial and scientific application..
Pros
Efficient diamond thread design for fast and precise concrete grinding.
Cons
Diamond threads wear out quickly with frequent use, requiring frequent replacement which can be costly over time.
Worked well for drilling multiple holes in 9 inch thick concrete posts around our house. , as HD and Lowe's don't have matching mandrels, so order those if you don't already have them.
