Norton(NOR62328) 3" Norton SG Blaze Speed-Lok TR Discs, Grit 36 (1) Package of 25

I do a lot of metal work , welding , fabrication and a lot of Autobody work. I have tried other brands like 3m , and lots of no name brands trying to find the most economical approach to my abrasive habit. Norton absolutely outlasts and outfits them all .As with any abrasives you can cloth them up in seconds and smoke a disk , or learn a better approach and save time and money .Paint removing typically won’t clog them up , they cut right through it and leave nice shiny steel in there wake . Mill scale however will clog them up and reduce their effectiveness greatly . I have backing plates from 3” down to 1” . As I’m using these 3” pads they mostly ware at the edge , so I will take about 1/4 - 1/2” off and reduce the backer to 2” and it starts fresh . I keep cutting it down to 1” and then it’s time to replace .I find the 36grit pads work the best for me , but if you’re going to fully finish your work you must be prepared to clean up the 36 grit markings , as they will not leave the surface ready for paint . But as for value for your money , you can’t go wrong .

this disc cuts down weld beads faster and lasts longer than any have tried for over 50 years of auto body repair now retired and hobby welding at home

The higher cost is totally offset by longevity

Qty is supposed to be 25, I received a box taped closed with only 23 discs.

Great long lasting disc

These things are awesome.

Great product and company
