All the bores in the package work well. Good product!

Used it for many times on metal and it works great.

I bought this set to use to file down some metal pieces so that they fit the door frame better. The set arrived on time, seem to be decent quality. I chose what looked like the right bit and successfully filed down the metal pieces. It worked fine. I cannot comment on longevity, as I haven't had them for long and only used them that one time. I will likely update once I start the next project.

must have, it cuts down metal faster than a flap wheel dose. It also holds up for a long time.

I use these almost daily for steel prep etc. and am not gentle on them at all. Have held up excellent. Don't even debate it just order them. Ps has nice little stand up holder included with the plastic case for storing them upright in your tool box.

We use these on our heavy equipment. They are good quality, and I am very pleased.

I'm impressed so far. Made fast work of my project. Doing a LS swap and needed to open up the flex plate holes. I started with some harbor fright crap....took a hour for 1 hole. I bought this set and had the other 2 holes done in 5 minutes total for both.

I have only used one bit on one job. But it was on very hard steel, and the bit did a fast, smooth job with no apparent wear.

Received as advertised and as scheduled

Bought these not really expecting them to be as good as they are, but after using them for quite a while, not disappointed. They cut very well and last a super long time!
