Ingersoll Rand Edge Series EC400-NS Needle Scaler Attachment, S

I have had the same scaler attachment on my service truck for about 8 years, the attachment has always worked properly and has outlasted about 7 ingersol air hammers.

Powerful fit right on my ingesalrand. Without a hitch perfect

Easy to install and use. Works very well and so far has been durable in a commercial shop in the rust belt

Given this is a bit smaller than the HF scaler I used to own (and broke multiple times), I was hoping it worked almost as well, but it performed better than twice as well. It tore through rust way faster than the previous scaler, and was much easier to handle.

I work on concrete mixers so I tend to beat needle scalers up pretty quick. This one was packaged well, fit perfectly on my Snapon air hammer, and in true IR fashion it works well and can take the beating that mixer mechanics can give it. Way to go IR!

Great attachment, sad that it’s more expensive than the gun it goes on. But it works great.

Hooked up to my cheif long barrel air hammer and my friends snap-on short barrel air hammer worked great on both of them

Ordered this to see how well it works, blew me away.Much more effective than a normal scaler, just chews through the thick hardened scale caused by moisture and dissimilar materials. I mean this thing feels like what I would imagine operating a browning .30 feels like, but and I can’t stress this enough you will break the needle driver if your gun is on full power.DIAL IT BACK! Depending on how your gun operates you will have to feather the trigger or turn it down but you absolutely with shorten the life expectancy of this attachment if you don’t. My PH3050 exploded the driver after a week.
