Mac flex head cut off tool?

[ptab01]

I am looking at a used one for under a hundred bucks & a new one at $200.

No details on free rpm speed r available -little to no reviews are found in searches

the used one - i always worry about buying used air tools - never know what one is going to get - watered internals - worn gearing.
i'd pul the trigger on the new one if Freaking Mac ever bothered to put out a Spec sheet on it's ****!!!

ugh -1800 rpm's is the free speed - I don't mind a slowed down ratchet if i am getting a bump in torque But for an air cut off tool that is pathetic Suppose i'll need to configure something on my own
maybe a flex shaft off an industrial die grinder -HHHHmmmmm

I have that tool and I'm pretty sure it must be 18 000 rpm rather than 1800.

dyslexia hits again- Thanks for the correction
still rather slow for a cutter.

Question for u since you are a proud owner - how quick are you going through wheels?

I looked at these when they first came out and the turn off for me was the fact that it has a flex shaft.....

I'm not, as I barely use it. The body is so fat that it pretty much ruins any advantage gained by the flex ability. Maybe the odd cut is easier, but for the most part a regular die grinder with it's much narrower body is lighter and handier.

It does, however, work as advertised and the pivot mechanism is very sturdy, if a little sticky to switch at first. I honestly don't use it enough to comment on wheel life.

NB: I took the guard off of mine and I am comparing to unguarded die grinders as I prefer them to specific "cut off" tools. I also run swivels on all of them.

I've never had mine apart, that's good to know. A split shaft with CV joint would have been nice...

Thanks for the info- I to chuck the guard off cut offs -they more hindrance than anything. they block your line of sight and prevent deep cuts
in the service we used die grinders 24/7

cuts like a son of a gun but just broke our second one now.

has zero power going to the disk, almost like it broke the shaft... and we never use it in the flexed position

I've had one for 15 plus years and it has been very dependable. I have replaced the flex shaft twice in that time period and have had no other issues with the tool. I do have to agree, that the tool is a bit on the fat side. The tool has plenty of power, but it's difficult to control the speed. It's all or nothing.

The flex shaft will eventually break but its a $30 part and easily replaceable. Word of warning, I just had the bearing in the head of mine explode today, gouged the shaft pretty good. When I disassembled it, it was bone dry inside. I don't see a grease zerk anywhere and can't really imagine it needs to be disassembled and greased periodically. I can only guess mine did not have much grease to begin with. Haven't even owned it 2 years yetz and of course MAC guy won't warranty it. If you do get one, I'd disassemble the head and make sure its well greased.

They are nice but if you use it hard and like to push on it dont be supprised when u break that flex shaft. My buddy breaks his constantly.
