84PCS Abrasive Mounted Stone Grinding Wheel, 1/8” (3mm) Shank Head Mounted Grinding Point Stone Heads Tool Grinding Wheels Bit Set, 2 Shaped and 7 Sizes 3mm,4mm,5mm,6mm,8mm,10mm,12mm

I like the various shapes and sizes. They don't wear down fast, even grinding/smoothing an aluminum threshold edge. I've used others that wear down pretty fast. Not these.

They do send the stated amount. I was a lil disappointed in how they don’t last too long individually but with so many in the pack it works. Good price for thee amount. Yeah buy them there okay.

I've been using a lot of abrasive bits this past month and tried a few brands. These seemed to last the longest, had a nice selection of head shapes and the shaft and bit overall were long enough to get into the areas I needed. I'd recommend these. They will wear but they are a very good bit for the price.

Used this to grind a deadbolt strike plate and it was still in good condition after. Most bits don't last as long. Very impressed for the price and durability

Works awesome. Nice little kit.

I wish each type was separated instead of all coming piled in the same baggy. Other than that they seem straight and none were broken. They work just fine.

These work great for those really hard corns that the cheese grater wont take off.. it puts out a distinct odor only described as like if a cat got caught up under a treadmill.. but whole bunch of sizes to get real tight in there if ya need to.. dont break apart if you miss and hit something with em..

Great wheels at this price point.
