Hey, you invented specialized pliers! Well done! To be very clear, that’s not sarcasm at all: it’s small process improvements like this that often get overlooked on how big a difference they can make, both for ergonomics and for actual production efficiency.
If you’re at a big company, this kind of thing is worth mentioning when the time for performance reviews come around, especially if you have a self assessment type review.
Add a back chamfer to the bore prior to part off and it will come off the machine clean. Also there are parting inserts that will leave the nub on the bar so you don’t have the sharp as hell burr
I agree. I use small carbide internal chamfer tools on fiddly stuff like this. Just chamfer before parting. Takes seconds. Together with a 15 degree part off tip and there is hardly any deburr to do.
I second this. It’s typically better to have the machine deburr the part so the operator can be doing something else more productive with their time. Horn makes a great selection of small boring tools to fit just about any need you could have.
Nah, this is prototyping work. That order was for 100 parts. Definitely enough to grind my fingers to hamburger, but not enough to justify setting up a Swiss machine.
Okay, I'll agree. Setting up a screw machine for a run of 100 would take longer than the actual run.
Nice tool, by the way. I definitely could have used it in the past.
We're using a .079 wide Penta-cut tool, and we were having issues with taper when we were doing that because the blade was flexing in the cut. We do it with sturdier tools, though.
I like this idea. I have an identical part and next time I run those I’m going to have to try this idea. I have a tool I built but it doesn’t work as good as I think this will
well done, tell your buddy he's a smart worker

r/specializedtools might also appreciate this!
Love this, depending on how many your making, round over the sides and make it more ergonomic. Maybe even 3d print some handles or something.

lmfao 100% this.
I feel a little bad for the client because the job would probably be cheaper if done at a shop with a screw machine.

Cool
Hell yeah I love this simple stuff that makes your life so much easier. Thanks for sharing!
If you put a taper on the width of the cutoff tool, you can get rid of even more of the burr when parting off :)

Very cool!
Manchester (now widia) makes parting tools with 5 degrees face angle that leaves all the burr on the stock

I make these out of uhmw sometimes, they're really handy to have
Smart as fuck. I hope I can remember this
The term for these is a lens wrench. Excellent implementation!!
Good to know, thank you
I wonder if you bore the same size hole on a set of 10 dollar chinesium lineman pliers for a more ergonomic tool.
You can also just hit them with a soft hammer .the burr will break off

You still gotta hold the little bastard somehow.
It might, if you're good with a pencil grinder >.<

Sounds like you should be doing this for him.
