Style Name: Tool with Case Verified Purchase
I had a hard time deciding whether I needed this and as a result spent a lot of time here and at Home Depot researching this.

Angle grinders are simple tools. All the major manufacturers basically offer slight variation of the same design. For 4.5" grinders you're basically choosing these things:

Switch: Thumb/paddle/trigger switch, locking/non-locking
Motor: Usually 7/7.5A (~3.5lbs) or 10/11A (~4.5lbs)
Miscellaneous: Tool-less guard adjustment etc
Price

That's about it. The closest competitors that I saw were the milwaikee 6130-33 and Dewalt D28110. Both of these have locking thumb switches. I thought milwaukee's switch is too small and flimsy feeling but I like the easily adjustable guard. The Dewalt has a larger and sturdier feeling switch but is heavier for a 7 Amp grinder at 4.1lbs.

This tool has what I think is the ideal switch for a grinder - paddle switch. It runs the entire length of the tool so it doesn't limit how you can hold it but means that anytime you let go the tool is going to stop. It has a small latch, positioned in the middle that must be flipped before the paddle switch turns the tool on. This becomes natural after a few uses and prevents the tool from coming on accidentally when you put it down. Thumb switches by contrast, either require you to hold the tool in a very specific way, or force you to reach for the switch to turn it off. For a hand tool this powerful that's not ideal.

So far I've only used it once to help a friend with rust on his car but given Makita's solid reputation (close or equal to Dewalt/Milwaukee) I expect this tool to last for a long time. On top of that of course, it includes a great case, 5 grinding disks and the diamond cutter. All round I think this is the best angle grinder out there.

This paddle switch grinder is a step up from the cheap ones you will find at places like Home Depot. It has enough power and is easy to use. Our company goes through a lot of grinders, as we work on concrete only where they take a beating and suffer under the conditions. This grinder is better than most, while affordably priced. The metal case is cool, too.

On a side note, DO NOT buy any equipment here from "CPO Makita", as they are nothing but a bunch of crooked re-sellers pushing defective equipment that they refuse to return or replace. Buyer beware - they stole from me with no remorse whatsoever, and they managed to keep my feedback off the web page, thus this oddly placed warning! Please be careful. I've never had a problem with items purchased directly from Amazon!

Amazon shipped quickly. The grinder is a comfortable size and weight. The paddle switch is easy to use and is a nice safety feature. I've used it now for 2 jobs but it suddenly died on the 2nd job - after no more than 30 minutes total combined use. I used it when it arrived to cut cabinet openings into Hardieboard (concrete board), a 20 minute job. I used it again two weeks later to cut three 18 in square concrete pavers in half. After 5-10 minutes use, it just stopped working while I cutting the 3rd paver. I now have to send it to a factory service center and I hope they replace it with a new one without a hassle.

I had this repaired under warranty. I was told by the factory-approved service ctr that the problem was a broken wire. No further problems since it's been serviced.

I wanted to clear up the confusion as to what exactly is included.
It comes with:

(1) 9557PB angle grinder
(1) Side Handle Grip
(1) Type-27 guard
(1) Type-1 guard
(5) Makita Grinding Discs for steel/stainless
(1) Makita Diamond Blade
plus owner's manual and the case of course.

The case is aluminum with zinc coated hardware and latches. They should rust in no time. I spray nuts and bolts on floor jack and other zinc hardware to not rust, but I don't want to lube up these latches - I'd never be able to open the case. Oh well - better than a cardboard box.

The case has eggcrate foam on the lid and tougher rubberized foam with cut outs for the tools and individual cutouts for each disc. Great protection for fragile wheels. Another thing I like is that the lid does not fully open. It goes a little past vertical and stops preventing damage to lid after a thousand times of throwing the lid open and it hitting the floor.

This is my first Makita (M*lwaukee and R*dgid fan-boy here). It's a great value and works great. It ate through a Br*nks R70 disc-lock without blinking. Its small size allowed me to maneuver behind the weirdly shaped lock (enclosed hasp) butted up against a corner and melt through the lock one-handed. I have a 7-inch R*dg*d angle grinder that has waaay more power and lethality, but simply would not have been able to complete this job due to it's size. Another testament to having the right tool for the job. In this case, smaller is better. I'll admit it doesn't have the power of the big boys, but i'm not cutting through foundation or 2" plate. I'm also not melting extension cords or flipping breakers every few minutes.
