## Customer Reviews

### ⭐⭐⭐⭐⭐ 







  
  
    Good quality drill bits
  

*by D***. on Reviewed in the United Kingdom on 26 August 2017*

Good quality drill bits, handy for removal of a snapped bolt in a car engine, being a left handed thread. Cobalt can be brittle, but with care it did the job nicely for me and I used a drilling and cutting oil.

### ⭐⭐⭐⭐⭐ 







  
  
    They did the job perfectly
