This fit perfectly on my Black & Decker Quantum disc grinder - so that I can now (more) safely use cutting discs. The use of heavy gloves, a face shield and safety glasses is still highly recommended. If a cutting disc breaks at high speed, the shrapnel (pieces) can cause seriously bodily injury. Be safe!

Works as intended use applies.

I was hoping to pair this with a proper cut-off wheel enclosed guard, but apparently none is available for my DeWalt model angle grinder.

I'll just keep the backing flange for future reference.

I lost my flange on my dewalt angle grinder so i have been using my other grinder. But when I saw this on Amazon with a remarkable price on it, i was shock. I was about to buy it on Homedepot for more money and i am glad i went to Amazon first, i was lucky to buy this earlier when the price was still low.
I flange fits perfectly just the way it should be and materials looks very solid, not the cheap ones. I recommend this product.

Ok Bought this little thingy to go with a blade like the other reviewer said was needed or helpful
at least. It cost 2.50 but shipping was more than twice that...they the silly vendor over packed this itty thing in a huge box for it's tiny size. And arrived in brandnew like condition which it was. A small packing envelope perhaps with bubble or foam lining would have been much smarter and greener and cost the vendor or me the customer a lot less to mail.....and gone first class probably too. Anyway it's what it is and since it's going into the stocking for Xmas with the blades I bought with the saw itself then that person might have a better take on it. If I needed it or not I'll find out. Otherwise no doubt at worst it's a spare that cost 2-3 times it's asking price to ship. Was not going green via the huge over sized box.....ok small box as far as boxes go but huge for this item.
Have a happy holiday if anyone is reading this...as if you would review a washers review????
