Used on different types of plastics,etals and woods. Very rpm sensitive so be careful not to burn them up. Otherwise the best for price!!!!

These work great 👍👍Had another brand it broke in 2 peices after few minutes of useOnly if I got this set first I would have been happy. I have used them many times they still work great

Good selection of bits for general metal fabrication. I found the specific shape and size selection of bits in this set to be very useful. I ordered these in addition to a few that came with my astro die grinder set and the ones that were included in the set were nicer and came in a much better case. This one doesn't hold the bits very securely, the part that is supposed keep them from coming out inside the case can move letting most of the bits fall out while closed, which happened during shipping. Some double stick tape, glue or any other adhesive could prevent this. But the real bummer was when I opened the case up the lid would just fall back down. On mine the holder for second row of smaller bits wasn't attaching well to the piece for the bigger bits. I took the pieces off and there's a slot with a detent bump on the smaller row piece where it's supposed capture the little pin on the bigger row piece. They weren't going to line up so I just put a screw through the side of the case as shown in the picture and it works great now. I also used the vhb tape in the photo to secure the piece that holds the bits in. I almost threw the case away but it's actually a pretty nice, really rigid little box and so I made it work! Hope the bits don't need the same degree of babying to work well!

Bought these to work on aluminum parts with. Quality appears good and the case is well made (especially compared to most that come with tools nowadays). I'll update the review if I find anything negative-- no update = all good.

I bought these to use at a heavy equipment repair shop and they work great, I wasn’t too sure when I first got them due to the price but after using them for a few weeks and putting them through some pretty rigorous tests they have held up so well that I have even been asked to get some for other people in my shop.

These bits were the only thing that held up during a recent project I was working on. Had to get in a small space to grind off an axle nut in a recessed hub and these bits worked great.

The carbide was not centered on the shaft correctly. The bits do not cut evenly and vibrate quite a bit. For the money, they are great, and the carbide stays sharp and hasn’t chipped, but they aren’t centered.

I use them to clean up holes cut on the plasma table. They have lasted longer than any others I have tried.
