12" disc sander recomendations

[bouldermsm]

Hi folks,

A nice nice tool allowance has fallen into my lap and I am infilling miscellaneous power tool needs. I am just a general tinkerer/hobbiest/carpenter/shadtree mechanic/maintenance type guy. I am in the market for a middle quality sander for metal and wood and have linked cheap, medium and shop quality below just from a quick internet search. many of this style type comes with a second, ribbon band sander on the same output shaft but I cant picture that use in my own garage, to say nothing about something else spinning near by and the increased clearances. I know Dayton once made really nice things but an not as familiar post-Grainger. Any experience with these or other similar units would be great.

oh, and Happy Birthday.

I have a 9" disc set up. Big advantage in cost and selection to use standard sized sheet of abrasive paper. I just use spray adhesive, then turn the disc running a shop knife around the edge to trim the excess.

12" discs are pretty expensive and are usually only meant for wood. Don't rule out a belt type grinder. It's just the ticket for a ton of metal shaping/deburring jobs around the garage.

I picked up the Grizzly from Craigslist for $75.00. The one from Grainger and if you look at Harbor Freight, theirs appear to be the same as the Grizzly. Regards Barry.

do you have a 10'' table saw?
craftsman has a disc/kit that you install in place of the blade that makes the table saw into a disc sander. worked that way for years with great results. the table saw has a bigger table that the average disc sander and also allow you to sand on an inside surface.

I eventually bough a good used belt disc sander, I use the belt part more than the disc part

if you want just a good oscillating belt/spindle sander I recoment the one from RIGID. its about $200 and is a great tool. have used the heck out of mine and love it

Well I guess they may seem $$$ but at a few $ per disk I don't find them to be bad.
Of course you can get any size in any material/grit/backing so I don't know where you got the idea 12" disks are only for wood. I have been running 3m cloth backed PSA disks on my powermatic model 31 disk machine for years and they hold up well and last box was about $23 for 10 of them. BTW they make them up to 36" in stocked sizes.

Not a big deal at all William. I know they grind metal, but not ideal at least as far as I know.

Powermatic lists all their large diameter disc grinders as woodworking machines, and just to be sure I checked a few abrasive suppliers. I only see aluminum oxide, very little silicon carbide and no structured ceramic stuff.

At $2.30 a disc, you're getting a good price, usually it's a bit more. It's just that for me, aluminum oxide sheds the grit real quickly against metal. I've used tons of bargain paper, including 12" discs, and for metal I come out way ahead with some of the better abrasives.

I can also still use the bargain stuff on a 9" disc. For me, I can't find all the variety that your supplier has, and 12" discs just didn't work as well on metal. Just worked out different for me, but I bet your machine is quality and I might see it different if I had access to good discs.
