Rubberized is Cratex. There is a fiber one called MX.
Having a Dremel is a step up from not having a Dremel,as far as a resource.
It might be considered an entry level tool that serves well enough folks still get the job done with them 30 years later.
I don't even know what they cost these days...$59? A guess.
For the price of a box of ammo you are "tooled up to be a gunsmith" .Well,you need a claw hammer with one broke claw,your Honey's manicure tools,a nail for a drift punch ,some sandpaper,a kitchen table and a cell phone and you can post on youtube.Someday,maybe even a vise!!
I think the issue is that just like with shooting or playing a violin,buying the tool does not buy competence.
If the public could buy a Stradivarius (OK,I spelled it wrong) for $59 I'd buy better ear plugs.
If your STARTING POINT is "My new gun don't work.I don't know why. I'm getting my new Dremel out" Or,"Gee,I got my new gun AND I have a Dremel,I want to do something...."
You may be about to contribute to the Dremel Reputation.My long previous post did not condemn the Dremel. I have worn a few out. I know what they do.
I will maintain that a large percentage of the real estate we have to work on is that zone between the peaks and valleys of the existing surface finish.
I say that as someone who was trained by a Master Mold and Die finish professional. I built molds and I polished them. You watch the valleys. Remember,we don't want to appreciably change size or form. I actually would calculate and plan the allowance for EDM finish depth into my electrodes so when I polished the cavity,it would be right.
You have to know when to stop.
Very often,polishing out the deepest of machine marks will only give you a worn out rattly gun. I knock off the peaks.Use the deep cutter marks for lube and sand traps.
Soft polish media,buffs,felt,etc are not best for anything but a surface that has been accurately stoned to at least 600 grit.You maintain accurate,defined geometry with stones and laps.
And the secret to a good polish is a good tool finish.
Please remember the recent post by a woman who was competing in a steelmatch with a recently purchased used handgun.
Her life was changed when her handgun discharged in her holster.
No,that is not the Dremel's fault.It took a Dremel and a person grinding with the dremel on trigger parts.(It might have been a file!)
Somehow,to a previously non -tool guy,a Dremel brings forth his inner Hephaestus, from the forges under Olympus. It may be a primal force as great as reaching puberty. Something HAS to happen.
I get it. Guns may not be the place to start.
