Success story
Fabricated metals

For weld grinding on carbon steel one customer reports that 3M Silver DCGW delivered 95% less wear and a 28% faster cut than their current aluminum oxide wheel.

Success story
Steel manufacturing

When removing laser slag from Hardox 960 stainless steel, 3M Silver DCGW lasted twice as long and required less operator pressure than conventional aluminum oxide wheel.
Get up and Grind
The 3M™ Silver Depressed Center Grinding Wheel is a heavy-duty wheel designed for use in aggressive grinding applications like beveling, slag removal, weld grinding and edge work on a variety of metals. You can rely on this wheel to help you to tackle your toughest grinding applications.

Great for Robotic Weld Grinding
In medium and high-pressure applications like robotic weld grinding, it's important to choose a high-performance abrasive that cuts fast and lasts long. The self-fracturing mineral in the 3M™ Silver Depressed Center Grinding Wheel will keep your robot grinding welds long after other abrasives call it quits, reducing downtime and maximizing efficiency.

3M Precision-Shaped Grain
The 3M™ Silver Depressed Center Grinding Wheel features 3M Precision-Shaped Grain which continually fractures into super-sharp points and edges that slice cleanly through metal, rather than gouging or plowing as traditional abrasives do. This also helps it to last significantly longer than conventional ceramic grain abrasives while maintaining a high cut-rate over the life of the wheel.

Advanced Series Abrasives
The 3M™ Silver Depressed Center Grinding Wheel is part of a new class of 3M abrasives designed to deliver an unbeatable combination of performance and value. Powered by the legendary speed and long life of 3M Precision-Shaped Grain, these Advanced Series Abrasives are ideal for a wide variety of metalworking applications like weld removal, beveling, edge chamfering and more — offering a longer life and faster cut than aluminum oxide, alumina zirconia and other conventional ceramic abrasives.

Rated 5 out of 5 by from Best grinding disk I’ve used. Used to use Norton but gonna be switching to these. Takes metal away and lasts so long.

Rated 5 out of 5 by from Long lasting I got this as part of a promotion package, very impressed with how fast it cuts but remains cooler than other brands and last longer

Rated 5 out of 5 by from Great product Works great at my welding projects Awesome product
Date published: 2019-04-02
Rated 5 out of 5 by from Longevity and cut rates are superior. Used on a few projects around the shop - was a replacement for a older wheel. The cut speed for grinding is very fast, and the few projects I've used it on still having it looking almost brand new.

Rated 5 out of 5 by from Worth every penny and more! I use various brand grinding wheel on a regular basis grinding through welds most of the time. This product removes material faster and last significantly longer than most other products I've used. It may seem like an irrelevant detail, but the material removed (the sparks) are significantly more substantial. Where as I have no problem grinding steel and have the sparks bounce off my skin for a short time, the sparks from this wheel are much hotter (I suspect dues to the greater mass of each particle). The time it takes to go through material is much less, puts less heat into the part, and I am blown away how long the wheels last. At this rate, I could pay two to three times more and still be saving money.

Rated 3 out of 5 by from Needs to be a spin on Grinds well but needs to be a spin on /rolock style
Date published: 2018-06-20
Rated 5 out of 5 by from Removes material fast and they last! I got a sample of the grinding wheel to try and I am impressed! I build and repair trailers as a sideline and do a ton of grinding. I have been using another premium brand grinding wheels but when I compared the 3M against the other brand head to head... The 3M wheel was faster (same grit) and lasted much longer than the other major brand! Time is money as they say and comparing the two costs ways they are very comparable so I will be switching to 3M because they save time both in grinding and saving time with less wheel changes and that means more productivity which means more money!
