Cutting off tool

I just ran across this tool today, I don't know how useful it would be, but I want one because it is one of many tools that I don't own, besides maybe it works great and that would be a bonus.

Looks scary to me. Perhaps that is why we don't see them for sale any more.

A 6" vise is overkill for a RF45 style mill. A 4" is more appropiate for that size mill & IMO 5" max. I have a 5" GMT vise on my PM45 & it's slightly too big. Not enough Y axis travel to make use of the 5" full capacity. Better to save your money rather than getting something too big & most importantly the weight. I take my vise of the table quite often, a 6" is still light enough for me to be carried by hand but I'm glad I have a 5". I also have a 4" vise as well. I prefer the 5" though.

But those GMT 6" Premium vises are pretty nice. I'd love to have one but don't need one on my current mill. But if you plan on upgrading to a full size knee mill in the future than the 6" will be perfect.


Here's what the 5" looks like on my mill.



I couldn't even complete this cut without my bellows & DRO scale getting in the way. Not enough Y travel & the 5" vise is not even maxed out.



Here's what a 6" vise looks like on another PM45 (gt40's)

Okay, but then cutting off bar up to 1/2" diameter is a pretty straight forward task anyway (lots of options). Pretty hard to argue with the view point that more tools are required - I can't imagine when I would use that one.

I don't think I would find a practical use for it either, but it is a tool.

Maybe as a tool collector it would be nice in a collection, but I like all the other safer alternatives.
