A "Lifetime" guaranteed grinding wheel.

Norton Norzon are a good product, fast metal removal and good life.

I have been using 3m cubitron belts on my 2x72 grinder exclusively for a long time. I did just buy some norton blaze belts to try out, similar pricing and reviews to the 3M. I can't believe how long the 3m last and how well they cut.

For my angle grinders I have been using benchmark abrasive flap discs. They are a good balance on performance and price. I rarely find the need to use a hard wheel anymore but if I do I generally like a softer wheel that cuts fast. I don't think I would be very happy with the lifetime guarantee wheel as I just can't see if removing material very fast. I've seen multiple reviews of the diamond cut off wheels that say they melt their way through more than cut.

One of my customers bought me a wheel kinda like that a few years ago.
It bounced terribly when in use,like it was not round,i tossed it.
You just could not control it,maybe mine was a defect?

I've tried the smaller sized ones for Dremels. They do the same thing. I don't think they're able to get any sort of balance with their diamond depositing process. Add in all the speed holes and extra notches and it's just a bad design.

I get that cost is a driving factor in a lot of areas when people use abrasives in the real world, but I don't see products like this actually saving much of anything. If it was that great, everyone would be flocking to them. I imagine grinders are some of the most abused tools in anyone's shop, especially when you hand them off to the lowest-paid guys to do the clean up or cutting apart. I wouldn't hand a $200 blade to an inexperienced helper and expect it to last long. The guy that doesn't pay for it certainly won't take care of it.

A 2x72 belt grinder is on my short list of projects. I'm thinking I wanna do something like this one: https://jerswoodshop.com/gen-2-belt-grinder/

I too am using benchmark abrasives. I find they are a good blend of quality and price. One of the gems I have found for blending especially aluminum welds is this one: https://benchmarkabrasives.com/colle...aration-wheel#

I buy their flap discs, hard wheels, and cut off wheels in bulk quantities. I've been getting my dry cut saw blades there too.
