### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Worked great
  

*by F***T on Reviewed in the United States on October 21, 2023*

I was skeptical of a hole saw that attached to an angle grinder. However, It won me over because it was easy to handle,  no edge chipping or wandering holes.. It even bored through the fiberglass coated 3/4 plywood underlayment with ease and there was no trouble getting the plugs out of the bit. I was a little hesitant with the price but turned out to be great value for the money.

Liked the overall product,  but most of all the length was perfect.

### ⭐⭐⭐⭐ 4.0 out of 5 stars







  
  
    Worked great
  

*by G***5 on Reviewed in the United States on July 7, 2022*

I only had one hole to drill to get a sump discharge pipe out of my foundation.  I have precast walls which are about 1.5 inches thick, but it's 5000psi concrete, so it's very hard.  I rubbed this bit down with some lubricating oil right before drilling.  This worked great, went through in less than 5 minutes without having to pull it out to cool or re-oil.  I can't really rate longevity with only one hole drilled, but glad I bought it.
