pneumatic cutoff tool quality

[littleboss]

I don't get much life out of my pneumatic cutoff tools. I have had several Campbell Hausfeld and Tractor Supply units. I just bought a IR to see if it's any better. Basically after using them a few times they don't have any power. I always squirt some oil into them before using.

Do they wear out that quick because they run so fast? Or do I need to find some better brands?

Thanks

Perhaps you are OVER oiling? Usually a drop a day is sufficient. Or insufficient air volume or pressure?

I have a bunch of CP’s IR’s and they are fine. My fave cutoff tool is my extended reach Aircat.

I had a Matco die grinder that lasted me for years. When it finally **** the bed I bought a new Matco.. it lasted two weeks.


Years ago I bought some cheapo ($7.99) die grinders from Horrible Fright with the plan to just throw them in the trash when they STB... So far they're all still working just fine.

Spray rake clean in the air inlet. Fire the tool up hustling enough to flush the **** out. Oil it with just a drop or two of good air tool oil. Make sure you air supply is clean and dry.

Sounds like they are mucked up internally. Maybe try flushing them with PB Blaster, Kroil, or even WD 40, then using an air tool oil like Marvel.

I have some air tools that are thirty or more years old that still work fine, although obviously not in a commercial environment.

That extended Aircat rocs, though!

Do you get water coming from the exhaust? My cheap hf still works fine, actually better than when it was new. I used to have to give it a spin to get it started. I ran a shot of carb cleaner through my air tools then oiled them up a few times but im sure there are way better options

take it apart and see how it works. you'll see why it isn't working. either you are getting dirt in the air supply, scratching and pitting the cylinder/vanes, or over oiling which makes the veins stick and not fling out and seal. once you get one apart you'll see how amazingly simple they are, and the only way they make power is by the vanes...and yes, I've had some where the veins were defective from the get-go and never made much power (cheap craftsman one).

To add to this, it is Marvel Air Tool Oil, not MMO:

^^^THIS. I've had this problem on several air tools. Disassembly and cleaning made all the difference. Of course, once I have it disassembled, I typically put in new vanes. I've resurrected an air nibbler and a Hutchins 800 orbital air board this way.

Clean, dry air is critical for performance and longevity in an air tool. That said they are tough and it's amazing the abuse they will take.

Many times just teardown and reassembly magically does the trick. Why , who knows. I’ve got HF and IR and had more headaches with the HR . One of my HF dates 1990 wimpy but works.

Right? I have 90's era HF air tools and they won't die! Of course, I oil them whenever I use them.

I've noticed that too. I suspect that it's just that the vanes get stuck in the rotor and teardown loosens them up. As I said, once I have it that far apart, I just stick in new vanes anyway.

I will take it apart, it will only cost me my time.

Step one is to remove the silencer from the exhaust outlet. Air tools have more power when they can breath.

Or maybe try cleaning the silencer.

If you do remove the silencer, wear good, high quality hearing protection.

Hearing aids cost around $5k.

I wouldn’t recommend removing the silencer....it’s not a smart move.

Let’s be really honest here, there’s no such thing as a quiet air tool. I put on something every time I pick one up . Same goes for battery drill drivers.

I don't know, the aircat die grinders are pretty damn quiet.

They are usually soaked full of oil and then become a magnet for dirt and gunk; further restricting the exhaust. Unless you want to put it on a cleaning schedule, remove it.

I wonder how I ever manage.
