    Who would have thought
  

*by E***N on Reviewed in the United States on July 27, 2022*

I have always used the star shaped chamfer bits and have never really had good results. They have usually left weird irregularly shaped cones as they chattered around instead of nice smooth finishes. I thought I'd give these a try and see what the fuss was about. I didn't think they would cut as well as they did. They leave beautiful conical chamfers every time

### ⭐⭐⭐ 3.0 out of 5 stars
