I used this on both metal and plastic and it works as designed. The bit is sharp and cuts through thin metal very well.

I used it to enlarge a hole in thick metal and it did the job and stayed sharp. Impressed with the quality.

I used this to expand the existing hole on the left. It¡¯s a corian countertop and took only a minute to finish
Laura Hill –
Haven’t tried this on harder materials, but for thin plastics, this has left a wonderfully clean finish, and being able to dial in the width this precisely has been quite helpful. Definitely recommended.
