3 Inch 150 Grit Diamond Grinding Wheel Cutter Grinder Tool with 1/2" Bore for Grinding Hard Alloy, Glass, Tiles and Ceramics 78x12.7x10x15mm 1Pc

Ordered for my wife who is doing tile mural artwork. The diamond # 150 grit is perfect for shaping to fit tile piece in a blink without chipping the porcelain.A great product for use on a mini grinder. For those who's grinder has a 10mm arbor you will need to make a bushing from 10mm to 1/2" to fit the wheel. Very simple just make sure it is properly centered so yo don't end up with a bushing that has a runout as vibration will cause problems

Works good , but was too tall for my mini grinder. I had to take the guard off. Ordered another. Used it until I got the new one. Works good on gemstones and crystals. Careful it is agressive.

I'm using this with spacers on my 3" mini bench grinder. The arbor sizes are different, but these little spacer/adapters make it work. There is not any noticeable wobble. The grinder itself is a work in progress but these help make it more versatile.

I’ve sharpened about 60-70tungsten on this so far and still going strong.And at least 30 was brand new never sharpened. Takes about 45 sec on a new tungsten. And about 5-10 secs to touch up a used tungsten

I set this wheel up for carbide lathe tool sharpening and TIG tungsten dressing. It cuts carbide tips like butter on the radial face and leaves a great finish with the 150 grit.The flat axial sides are perfect for dressing TIG electrodes and since the surfaces are not shared with carbide cutting it keeps the TIG tips from any possible contamination.Also impressed by how true it runs when properly shimmed on a (3/8" arbor) mini bench grinder - it's difficult to see that it's actually spinning! Overall, a great value.

I bought this to use in my Harbor Freight Mini Tool Grinder. I replaced the buffing wheel side of my grinder with this. It just barely fits inside the cover for the wheel, but it did fit. I had to make a spacer to fit on the motor side of the wheel to space it out a bit and allow the nut and washer to tighten up properly though. Does a fantastic job of grinding TIG electrodes and lathe tools.

Cheap quality wheel, doesn't run true, it can be used to grind tungsten free hand, the diamond coat seems to hold, i dont use it heavily.

I saw many reviews that mentioned the 3" bench grinder from HF as an option for mounting this. That grinder has a 10mm arbor diameter, and only one of the three options for this product has that exact size hole in the middle. Reviews for all three seem to be lumped together, so some mention that they had to make an adapter to fit a disk with a 1/2" hole. This is easy if you have a lathe, but if you don't, make sure you get the one with the 10mm bore. It's listed in its description as having a 3/8" bore, but that's not accurate. It's 10mm, and it fits the HF grinder just fine.As others have said, this combination is a fine way to either touch up a carbide tool or re-point a tungsten electrode. For me, this puts two new tricks up my sleeve.
