    Another nice cutter!
  

*by A***R on Reviewed in the United States on December 13, 2023*

I have been having great success with these, I had never heard of Speed Tiger, but the price made me try their chamfer tool, I now have two sizes of that cutter and they are better than any chamfer tool I have ever owned!I use this cutter to cut everything from plastic to stainless!

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Great for cutting aluminum
  

*by E***L on Reviewed in the United States on May 16, 2023*

These bits work great on aluminum but do not work on steel.  I cut a lot of recievers and bought a few of these. A friend needed some milling work on a piece of steel that really just needed cleaned up burs. Well it ruined the bit. The steel in the slot was stronger then the bit steel.  But they work great on aluminum.

### ⭐ 1.0 out of 5 stars







  
  
    Broke in 3 pieces
  

*by A***R on Reviewed in the United States on November 20, 2023*

I’ve bought several items from this manufacturer, with good success. During a 1” deep operation, in aluminum, on fine feed, just exploded in 3 pieces, also ruined my part with 40 hours machining. Very disappointed. First time I’ve ever left a comment
