### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Works great
  

*by D***N on Reviewed in the United States on September 3, 2024*

These deburr bits are really great.  I fabricate items that I’ve made in my blacksmith shop, sometimes with my welder.  These little guts are great for removing welding slag in small places that can’t be reached with an angle grinder.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Works well, nice variety of shapes
  

*by M***G on Reviewed in the United States on May 8, 2024*

These cut well, balanced well, sharp and are not wearing out too quickly.  Better value than I expected.  I would buy these again.
