### ⭐⭐⭐⭐⭐ 







  
  
    Good quality
  

*by A***R on Reviewed in the United States on February 23, 2021*

Trying it this weekend but I can feel the heft

### ⭐⭐⭐⭐⭐ 







  
  
    Annular cutters are expensive, but really useful
  

*by D***R on Reviewed in the United States on December 7, 2012*

I recently started using annular cutters for cutting steel. They make what was formerly a painful job easy and the results are very high quality. Make sure the work is securely clamped. That is a must.

### ⭐⭐⭐⭐⭐ 







  
  
    Perfect fit!
  

*by P***L on Reviewed in the United States on January 2, 2016*

Bought it for a friend.  He said it was exactly what he was looking for and for a fraction of the cost other companies were asking for it.
