Your cart is empty.3M Cartridge Roll 341D gives you easy access to small, hard-to-reach spaces for sanding and finishing. As the outermost abrasive layer wears down, the cloth backing frays to expose fresh abrasive layers for continued cutting action.

I like these for finishing filed , ground or machined surfaces, or for demurring before coating or polishing.

These are really worth the extra money over the ones that you typically get in a porting set like SA, Mr. G, Harbor Freight... actually any that I've used before. They cut better, don't get plugged up as fast, last longer and you can turn them up to a higher speed and cut faster with a smoother finish than others (you can cut at speeds that would just have the others fly apart).

These did what they were intended to do and more. They held up well and moved a lot of material (for their size). I will be ordering these and some 3M tapered rolls in the near future.

These hold up extremely well! I port cylinder heads and over the years have tried menu brands cheap and expensive. I’m impressed. More then worth the money. One roll lasted over an hour of continuous use.

Long lasting, don't buy any other brand. Spend a little more up front and it will pay off in the long run.
