The plastic was likely used as bearing material, with low friction, that avoided having to make a significantly mire expensive method of allowing the deburring blade to easily spin.Yes. Correct.
The piece that broke appears to be made of plastic. It is the piece which holds the "debur" tool.
And HERE is why it is exactly the wrong material to use:
^ That's it right there.
And what does @Beerhippie do with that cutter when the job's done?
Does he very carefully lay it gently into the "Bucket Buddy" so as not to disturb any of the other tools or create any more dust?
Or
Just toss the thing into the bucket and say "Time for a beer?"
Other than the handle, putting a piece of plastic on that tool is only going to result in tool failure.
Whoever designed that thing simply failed to "read the room" and understand his prospective customer was not about to treat it gently - he's working on the clock.
I needed to cut some conduit to fit in the car for the ride home from Lowe's, so I bought a new Klein cutter, then left without buying any conduit! Doh!
I had a list on my phone, actually a picture of the written list. But I guess once I got distracted by looking for something to cut the conduit with, I forgot about it.I think we've all been overlooking an important part of the OP:
Sounds like **** I'd do. Go for A, but also make a mental list of other items "while in there". Get all the other stuff, get back home and realize I never got "A"...
I started keeping a checklist on my phone

That holex one looks a lot like the Klein. Different contours but same idea. I might look into what they offer.The plastic was likely used as bearing material, with low friction, that avoided having to make a significantly mire expensive method of allowing the deburring blade to easily spin.
Rothenberger, and Virax, and some other high end plumbing tool brands make similar cutters, with similar deburring tools, also mounted in plastic, slide out fittings.
With Rothenberger and Virax, it is likely that you can purchase replacement parts.

I used to use the checklist but got to where I hated having to get my phone to add stuff, or I would find something I needed and not have my phone handy so I would just write it on whatever was closest. Probably ought to go back to it, but generally the photo works. I could just as easily place check marks on the pic as I get stuff but I still have to remember to do it.
Me as well. Are you guys saying that they don't sell these anymore? I've had mine for a couple of decades so I guess I've never needed to look for a new one. But that plastic ********? Throw it in the trash, lol
Now you're talking about real tools there.How about the Ridgid Model 15?


^ that's it in a nutshell.it's cheaper.
Do you use the wheels for steel tubing or just the regular ones meant for copper?
Never tried cutting sanitary SS with my Rigids--but it would make a very square cut.
A local supply house is a Ridgid distributor and they carry both the standard and heavy duty cutting wheels. They buy them in bulk packs and sell them loose/individually. They get them cheaper this way instead of the hang tag blister packs you see online, and they pass the savings on to the customer. The HD wheels are not much more than the standard wheels so I just use them for everything. One thing I like about Ridgid is that you can store an extra blade in some of their handles. Looks like Klein copied that too.Do you use the wheels for steel tubing or just the regular ones meant for copper?

andIf you're going to use a tubing cutter a lot. Bite the bullet and get a real Rigid or Imperial Eastman.
