You ever used any other brand one to be able to see any differences?
Yeah, the burgandy or some name like that. 2 of those broke so using the milwaukee now. Do about the same thing as long as they work LOL. The milwaukee seems to squeeze a little tighter but thats about it.
Burndy. They've always made the top machines. Milwaukee's trying to make everything now a days. Milwaukee wasn't even a brand until more than 30 years after they began making them.
It is really strange that the Milwaukee circumferential (round) dies for the 12 Ton Crimper are bottoming dies, with the result that the crimp has slivered ears or wings (which are not wanted and dangerous in handling). If you look at traditional circumferential dies from Burndy (6 ton W dies for example) or the Panduit equivalent, they do not bottom. This is accommodate making ears that are not sharp but rounded (the inspector for a four crimp will look for a consistent rounded ear pattern), which historically will pass inspection for UL certified crimps, especially if you have the Burndy (or equivalent) symbol embossed in the crimp. For the UL crimp you want a single crimp in each required position, with the proper certified force needed, embossed logo with die number and consistent ears.
In some cases for UL crimps you may have to use a die for a unique wire type like K or M (generally called Flex in the US due to the high stranding). Usually, if you use a non-bottoming W die you are covered, but not always (depends on the lay of the cable). If you want to use a bottoming die (either round or hex) you would have to experiment in order to find a die that bottomed without producing an ear (sliver). You would then cut through the crimp to inspect it and if okay this is what you would show the inspector. You can see how a non-bottoming circumferential die is much more forgiving in that if an ear is produced it is neither large or sharp.
The trend in the USA is to move away from circumferential non-bottoming dies to hex bottoming dies, which have a long history in European electrical distribution where you match the die and lug to the wire cross sectional area in square millimeters (there is no color coding) for type B stranding. Hex bottoming dies (with proper matching of lug to wire) will produce consistent crimps without ears due to the additional symmetric corner area in the hex pattern (the hex geometry is better suited to provide the needed expansion area when the die starts to bottom). Greenlee makes color matched hex bottoming dies for the US (AWG) market due to the teams (German Klauke) experience in hex die design. T and B have followed this trend with their latest tooling and it looks like Panduit will do the same.
There are a few transportation applications (auto and marine) where crimp ears are not wanted, and traditionally have always used a hex die (lugs may not be color coded like "Battery" lugs from Panduit). Mainly to facilitate the use of sealing the crimp with dual wall heat shrink tubing without possible damage from a sharp ear.
thank you.
I've never in my life used a milwaukee electrical tool that I have liked. And I don't do side work anymore, so that excludes the stapler. Which may be the only trade specific, electrical tool that they've ever made that was any good.
Can you change the die for a 6 awg connector, you can't crimp with a dial crimps? Mechaninca; or hydraulic!
Very cool! Thanks for sharing!
Glad you enjoyed! Of course ☺️
Mines has served me well but I just started having an issue with it. Without warning the release trigger will not engage so I can't release the crimp. The crimp went to full cycle until the green light came on but when I tried to use the release trigger it wouldn't budge.
You’re suppose to rotate it 90 degrees so the stuff that comes out from the crimp isn’t all on one side
