Ingersoll Rand 422G Edge Series 5" Air Angle Grinder, Powerful 1.0 HP Motor, Locking Lever with Tease Throttle, Front Exhaust, Anti Vibration Hand Grip, Black

Well built tool far superior to any electric grinder. Has good power and is smaller than the other grinders I have used in the past. Front exhaust is the way to go in my opinion. I'm not a huge fan of the rear handle exhaust tools. All aluminum body. Best grinder you can get for 100 bucks

ok, a little bit of background, i am a welder and i work for caterpillar. i do a lot of heavy grinding on steel, aluminum, brass. concrete you name it. in the 10 years i have been in this business i absolutely love this grinder! its solid, well built, professional looking and most importantly performs well beyond the expectations i had for an air grinder. all the other welders that i have let use this thing are jealous. its better than my dewalt 7 inch grinder and my makita 4 inch grinder. i will be from now on buying ingersoll grinders. well worth it!

good quality.

This is by far the best pneumatic grinder of its size and price by a large margin. With 20+ years of welding experience and working in as maintenance in a welding shop that reconditions railroad components and have tried multiple brands of pneumatic grinders in 4.5, 5, 7, and 9 inch varieties. Now I can only vouch for the past 3 months of continuous, daily use in a professional setting, with two 100 hp compressors, and automatic oilers setup but this thing has more power and has outlasted other name brand grinders and is still going strong. Now for my opinion, this does require some decent air compressor to feed it at a minimum 30 gallon or larger depending on your usage, for the longevity of the tool an air dryer is preferred and as long as you properly oil the tool it would last you a lifetime in the home shop environment, for comfort the diameter of the body is on average slightly larger than other grinders in this class but it fits the hands well with less vibration than others. For our use on average the 5 inch wheel lasts 200% longer compared to the 4.5 inch with only an increase of 20% in price with only negligible difference in tight clearance operations. So good.

Awesome little air grinder. Lot’s of power. I would recommend a water seperator for your air system if you’re using it to prep for welding.

Poorly engineered. The collars will not hold the blade tight. Struggled for hours trying to find out why it would not tighten. Had to remove screws to get it half tight. Ending up leaving out the screws and adding a washer under the collar to hold the blade tight. Total BS that I had to do this right out of the box. Piss poor instruction manual. Last Ingersoll Rand product I buy.

I bought this Ingersoll Rand 422G 5-Inch Edge Series Air Angle Grinder on Amazon.com around April of 2015. I give this air grinder an overall rating of 3 out of 5 stars. I will start off saying that the price is just right, it didn’t break the bank. This grinder is a bit bulky for my liking but it is solid. I do love how the exhaust is in the front blowing everything away from you. The tools provided to tighten down the disks could maybe be improved a bit, they were a bit too short.Power wise it did alright. It has enough speed to do whatever you want but it could improve on the torque aspect though. With medium pressure applied it does bog down. Always make sure to oil it before every use, all it needs is three to four drops. I neglected to oil it like I should and the veins inside the grinder itself wore out. Now with the slightest pressure it completely stops. There is also a little screw on the very end or the head were you can grease the gears. Always make sure that is tight as it has a tendency to wobble loose after a while. Maybe a little blue lock-tight can help to. All in all it’s a great buy at a friendly price if you don’t do heavy work with. I fabricate for a living and use it a lot. Would recommend to a friend if its just for medium use.

This grinder works great! It's a little big, so don't expect to get into any small areas. In all the areas you can access, it really does a great job. I usually use it for bringing away rust in welding areas, and it blows right through it. I would recommend this to anyone interested in a high quality grinder. It works just as flawlessly as my co workers MAC grinders, but at a fraction of the price.
