80 Grit 3 Different Shapes Head Mounted Stone Point Abrasive Grinding Wheels Bit Set with 1/4" (6mm) Mandrel for Rotary Tools

good quality

These grinder heads are a great size, very good value. They are easy to use. The ones I have used out of the pack have held up to challenging tasks.

Worked as expected. Seems well built in use.

Just what my husband wanted, thank you kindly. Sincerely Cherry

I used them to lightly sand my decorative concrete bricks. Bad Idea. They worked for about 10 minutes before the grind wore off. One was out of round!! wobbled badly thus was good for nothing. I have been using the dewalt brand and will stick with them. I would say they might be good for something but not for sanding concrete lightly!!update-- I have upgraded my rating to 3 stars. I retried these on softer concrete and found them to be useful-- still not as good as the dewalt brand. they deserve 3 stars.

It does a good work. Great price.

This will last me Thanks

It wasnt well balanced, ran out all over the place, Was using it on my tool post grinder and had to true it up a bunch but it did the job and didnt blow up in my face with all the trueing so not bad. Delivered fast.I dont know how someone would use this with a hand held tool it is real out of wack from the start.
