IR makes excellent air tools. That being said, they missed on this one.

Power is good for a 4.5 grinder. But attaching and replacing the discs sucks. There is no lock, or a nut to hold it from turning. Instead, you use a hex wrench to remove a little screw, then another one to hold the shaft while grabbing the disc to spin it off. If you ran the disc down too small to get the leverage to spin it off, then you need a third hand to use a wrench. If you chew up the little screw,

which I'm certain will happen, then you're definetly scrud.

My old grinder, another IR, had a little nut shaped portion on the shaft that you could put a little wrench on, then spin the disc off.

I had hoped the new one would have evolved to a shaft lock.

Update 3/8/13:
Already, the trigger gets stuck, so hooking to air it suddenly turns on. Pretty dangerous.lock.

I've been using this Grinder for approximately a year now and find that it is my "Go To" Grinder. It has plenty of power and I find the disks easy enough to change. When using the Grinder properly, (from the outside edge not laying it flat) there is no chance of damaging the lock down screw. Hope this helps anyone that needs a powerful light weight easy to use Grinder.

I'm going to look for a better cutter. This started falling apart within a week. The little valve that the trigger pushes on fell out and I had a heck of a time finding the tiny parts. Finally epoxied it in. That sucks. Doubt they would return my money. Will change review. No reply so far.
Note, regardless of what the book says, oil this at least 3 times a day or it will slow down and get draggy like it is going to seize up!
Oh, and be careful, these things earn the term MEATAXE!
