Advice on small dremel metal cutting wheels

[DuncanS]

Didn't know about the ethnic slurs--agree on you decision.

I know TK was harsh, but I always looked forward to his advice which was usually pretty good and on point. His products are good too. The problem was the "T" actually stood for tactless. I'm sorry he's gone.

Duncan;

It's a minor thing, but having the paper washer between the head of securing screw and first disc is pretty important to prevent spinning (and shattering)...mine is still the original, but pretty beat up at this point...I expect I'll replace it with a piece of cardboard along the lines of a matchbook cover (cause that's what the original sure feels like!)

...and BTW...I have just needed to make some "glass interface washers" to allow the hinge hardware on an 1800ES (the "Sport Wagon" with the big rear glass door) to be installed...a situation not unlike this where a metal hardware must secure a brittle material...I used 0.044" fiber filled resin "Fishpaper" for this...it's very solid (and I expect much more UV stable than the OEM nylon washers) so will allow securing metal hardware to glass and take up the compression with no chance of shattering the glass...maybe using a washer of this material would work well for the cut-off discs also...am I over-engineering this...?

Who is Terry Kay?

Forum; I have broken many a red disc in the Dremel also...and being extra careful not to subject the disc to lateral force, only helped by prolonging the point at which they would shatter a little...then, I heard about the "double them up" tip mentioned early in this thread...and since I didn't really need a super thin slot, I tried it...Result: a marked improvement to the point that I now wear the disc(s) out (I most often use it for a specific job, where I must cut pretty hard steel) instead of shattering them...

Abscate; We tried "seeing the sun" yesterday, but it was too freakin' cold outside to do any work (here in CT, so I expect, not much diff from you in upstate), so we adjourned back into the cottage and did some sample rivnut setting (without the tool), to work out the method at the vice, in preparation for installing the Fog Light brackets...those pop rivets seller includes are too small for the holes (as YT "Gotta Split" also found out), so we are going to install 1/4" rivnuts which should hold the brackets well...later this week,its supposed to warm up...then I expect we will get more done outside, and play less "keyboard expert"...

Cheers

Wow--Amzaing how a simple request for information from the OP brought out the Terry Kay in us.

Thanks for the info on the reinforced inexpensive discs. I have the dedicated arbor, but never use it as the discs are so expensive, so thanks for the alternative.

I use only red discs 'cause I was too dumb to know any other choice. Always double them up. Sometimes I have a spinning problem, which I've discovered is mostly due to the threaded hole in the arbor not being deep enough. When the wheels are worn down to small, I use the nub of one of the old ones as a washer and it spaces the screw out far enough so there is never a spinning issue.

Buying some reinforced ones immediately.

Love my Dremel. Been through dozens. Single speed, variable, two speed, they all work. Couldn't live without it. I say to friends, to build a boat you only need a chainsaw and a Dremel. Anything in between is a wast of time.

Good info here. I’ve struggled with those red disks too. But less so when I’m using the rotary extension.

Those are good looking louvers. Patience and skill = good results.

The red disks caused Covid. They tried to get the new ones in time but Dremel was too late.

Isn't that always a consideration?

I would mention one other consideration. Although I have not had an issue with the discs spinning on the arbor, and with proper assembly of arbor/disc and appropriate use of the tool, I'm not sure how that is possible. But if you are doing assembly correctly and operating the tool in a manner that causes the disc to spin on the arbor, then if it did not spin then the rpms would drop significantly and you would burn out the motor very quickly. Although I have not been in that situation, if I was then I would feel better about ruining a $0.10 disc or an arbor rather than paying for the $3 discs in order to ruin the machine.

All I'm saying is please stopping fighting over dremel abrasive discs.

Just goes to prove the validity of what a wise man once told me:
"There isn't a project in the world that can't be screwed up with a Dremel"
