What brand 3x21 sanding belt that doesn't break prematurely? | Sawmill Creek Woodworking Community
November 2, 2017 - I'm going to order some 80 and 120 grit, 3x21 inch Mirka belts and see how long they last. Looks pretty good and I'm encouraged. Thanks for sharing, Mike ... I have belts from Industrial Abrasives in Reading PA. on the small Porter Cable belt sander and 6 X 48 machine.

Best sanding belts?

Brand name belts will do just fine. Anything that isn't budget stuff like harbor freight. HF makes some OK machines and some really garbage abrasive.

https://trugrit.com/

I buy all my stuff from trugrit.

You probably don't need to bother with ceramic belts since your machine probably couldn't utilize the advantages it gives. Maybe get one to try it out (for fast metal removal).

Keep in mind, loaded abrasives like norax and trizact are for finishing. They will crumble if you try to use them to remove metal due to fragility. The advantage is that they provide a more even finish and last longer than standard single-coat abrasive belts

Let me know if you have any other questions

What brand sanding belts do you guys use?
VSM ceramics are the go-to and what you are buying when you buy from most distributors. (Preferred, Red Label, Etc) Preferred Abrasives has the best costs for smaller sized orders and fast flate rate shipping. More on reddit.com

who makes belt sander belts that don't break? | Sawmill Creek Woodworking Community
November 28, 2020 - A family member used to work for 3M selling industrial abrasives. Sander Belts have a shelf life. Buy what you plan to use immediately. I have not had issues with belts for stationary sanders. Only belts for portable sanders. No longer have a portable belt sander so cant say if shelf life issue still applies.
