I have a few Fluke DMMs that I want to get backup probes for.
My ideal probe is one that will accept screw-on accessories such as various size alligator clips, micro-clips, and mounting lugs.
A 'kit' with all of these accessories would be idea.
Would like the probes to be decent quality. The closer to OEM Fluke or Pomona quality with more reasonable prices is what I have in mind.
 
Most of the aftermarket stuff on ebay seems to be junk. I did some searching on aftermarket probe sets and found this one which seems to be a good match to what I am looking for.
https://probemaster.com/8000-series-kits/
I've checked some of the electronic suppliers that I know of (Globe, Newark, etc.)
and have found a few options but not sure how good they are.
 
Suggestions for alternatives or other potential suppliers are welcome.
Thanks

The Probemaster ones are _gorgeous_, and insanely cheap for what you
get. The wires have very supple silicone insulation, not the cheap PVC
crap you get on the Chinese ones. The gold plating also holds up well,
though it does eventually wear out on the sharp points.
 
Other than that, they stink. ;)
 
I don't use anything else on my meters.

This tool?
<https://www.milwaukeetool.com/Products/Power-Tools/Fastening/Impact-Drivers/2450-20>
The 2450-20 is the original M12 model. The 2450-22 is the laster Gen
2 model.
 
The switch and PCB assembly is available:
<https://www.mmtoolparts.com/store/media/diagram/files/2450-20_b59a.pdf>
<https://www.mmtoolparts.com/store/media/diagram/files/2450-20_b59b.pdf>
<https://www.mmtoolparts.com/store/media/diagram/files/2450-20_b59c.pdf>
Note that there are 3 models.
2450-20 B59A
2450-20 B59B
2450-20 B59C
I'm not sure I have the correct diagram to match your trunacted model
number.
The PCB (item #5) costs as much as a replacement driver:
<https://www.mmtoolparts.com/store/catalogsearch/result/?cat=0&q=14-46-1705>
 
Maybe you should consider buying a parts driver and swap PCB's?
<https://www.ebay.com/itm/Milwaukee-12v-1-4-Cordless-Hex-Impact-Driver-2450-20-M12-for-Parts-or-Repair/153907966118>
$24 is too much. Off the seller some lesser amount and shipping. He
says it "doesn't work" which can mean anything. Ask for details.
 
More of the same:

<https://www.ebay.com/sch/i.html?_nkw=milwaukee+m12+2450-20>
(dig through the listings).
 
Good luck.

2450 is the base model number. The -20 or -22 means bare tool or kit.
The 2450 is not longer available - the 2462 is its direct descendant.
The 2553 is the latest and greatest.
 
The 2450 PCB part - $60
A 2462-20 (Amazon) - $50 https://www.amazon.com/dp/B01E6JRJUO/
A 2553-20 (Amazon) - $99 https://www.amazon.com/dp/B077ZYMK1W/
 
My nature is reactionary: the old has been good, why do I need the new?
But I fight that & in this case I'm going for the 2553.

I volunteer at Habitat and Milwaukee has a deal with them whereby
Habitat gets tools from the Milwaukee return/refurb facility for next to
nothing. I get to repair some of those tools and the majority have bad
switch-PCB assemblies. So I would not ever take a chance with a
doesn't-work eBay tool.

Walmart == Made In China Store
 
Even those who lower
their expectations
are often disappointed.

I randomly checked several newsgroups for sample messages and the
above message and the covid message were the only messages. It's like
these assholes posted to every newsgroup. What a waste of time.

Looking at the URL structure this is some service (grex.com) that hosts
user accounts (~henced) where someone has hosted a page. That someone
may not at all be related to this spam, it may be a hacked account.
 
The article was posted on usenet via another service, but that account
already has been shut down. Of course it will be quite easy to create
a new account for the next run.

Thanks Mikek, that would make for a very strong joint, if my current fix
breaks I'll see if there's enough plastic material to support this
approach. Cheers.

Wow! I just got back on Usenet after literally 18+ years and it's great
to see this is one of the last text groups still active with real people
talking! Good to see Sam Goldwasser and others still on here. Sam
incorporated a "tip" I made regarding vacuum tube televisions on his TV
FAQ back in 1997! I had a lot of great memories lurking and posting in
this group from 1995 to 1997. Thanks all!
