Rotary tool accessories

I've used a 20% off Harbor Freight coupon to make test purchases of small consumable items. Blades, grinding wheels, drills etc.

Given the price I've been content with performance.

I had a black and decker wizard, their version of a Dremel type of tool. I got it in 2002. It worked great until about two years ago, when it expired.

The cut off discs that came with it were practically bulletproof. Don't know where you might get them. (I've exhausted my supply, so I couldn't provide a part number or any specs).

I now have a Dremel tool and use their cutoff discs. They've been ok so far.

Jerry, it looks like even the industrial supply houses (MSC, Grainger, etc.) that I deal with at work carry only the Dremel brand wheels. Not many players in the market...

The statement that 'there aren't too many suppliers' made me think about Foredom, a rotary tool company (and there are others of those too). I just checked Foredom's website and they have abrasive discs that needs a mandrel.

I am assuming that this is what most of us call a cut-off wheel, but I am not certain about that. Please advise/inform/correct me if there are distinctions that I am unaware of.

Kutzall is I think a brand of bits and burrs for rotary tools, and I believe there at least one other major brand in that space (that might do cut off wheels).

Check out this type, available from Dremel. It’s what I use and is much more robust than the fragile smaller ones they sell.

Have used these. They broke at the shaft connection before wearing out.

My brother had one of the Dremal setups. I broke more then I cut with them. I went back to the mandrel style.

Baddog makes an industrial strength cut off wheel that works on a Dremel. You have to pay attention to the mounting hole diameter. Depending on your setup you may need an adapter. https://baddogtools.com/product/1-25-handi-disc-ii-diamond-wheel-for-dremel-tools/

My own experience

John K Jordan

In my experience Dremel grinding wheels, cut-off wheels are relatively expensive and of poor quality. I have had small cut-off wheels come apart before they wear out....

I have a different experience. I use the small abrasive Dremel cutoff wheels a lot (and for many years) and almost never break one. I find them very robust and never break unless I mess up and turn or tilt one during the cut - they HAVE to be held steady, especially for deep cuts. I almost always wear them down to a nub until they are too small to be useful.

When I do break one, it's my own fault for not holding the wheel perfecting straight in the cut groove. I always support my hand to keep the dremel and the cutoff wheel straight.

Note that they come in two different thicknesses the 409 and the thicker 420, I think. I buy them in bulk in 36 or 20 disks in little containers and one container lasts me for years.

I have some of the larger reinforced wheels and I don't like them and rarely use them.

BTW, I use the thin ones to resharpen bandsaw blades. I typically resharpen a dull blade 3 or more times before I replace it. I hold the dremel by hand and lightly touch the side of the wheel to each tooth. Doesn't take long for my 142" 3tpi blades and saves a lot of money.

I also use them to cut slots in stuck philips screws to use a flat bladed impact driver. I use them to cut off various things such as bolt heads, allen wrenches, and shaping card scrapers.
