### ⭐⭐⭐⭐⭐ 







  
  
    They Really Work!
  

*by R***E on Reviewed in the United States on January 10, 2020*

I'm drilling through 1 1/4" hard granite. I tried a similar Milwaukee bit from the orange big box store, which cost $16 and these bits did every bit as good, or better, that the more expensive bit. I didn't expect this since I was getting 10 for the price of 1, but it's really true. A single bit has easily gone through two holes and I'm pretty sure I can get a third on the same bit. As others have said, take it VERY slowly and be patient. I'm using a 3/8" corded drill with probably about 200-300 RPM and generally light pressure. Takes about 10 minutes to get through one hole.

### ⭐⭐⭐⭐⭐ 







  
  
    Great performance for the price! Recommended!
  

*by L***R on Reviewed in the United States on March 1, 2021*

Definitely recommend these bits.  Worked flawlessly on hard porcelain (PEI 5) only used 1 bit to drill 4 holes on wall tile.  Drilled slowly while constantly spraying water on the bit with a spray bottle.  I expected much worse performance for the price of these 10 bits but I didn't even have to use more than 1 bit.

### ⭐⭐⭐⭐ 







  
  
    Good value
  

*by M***S on Reviewed in the United States on December 29, 2019*

Did a good job cutting through mullite ceramic plates. 16 holes with one bit. Made sure there was good water flow to cool bit and clear cut material out of the hole. Bit still seems to be in perfect condition
