        A Metalworking Must-Have
        Very compact, more than even the previous Milwaukee grinder. The motor housing is about 1 inch shorter. Hand placement is about 1 inch closer to the disc (although plenty of clearance). The new motor still has tons of torque, and there is no lag in spinning up a heavier grinding disc. There's about a 2 second coast on power-off; this model does not have the quick-stop braking action. I'm a big fan of the no-tool guard. It has to be the best feature, literally you can attach / remove the guard in 2 seconds, and adjust it just as quickly. It's locked by a steel pin, so it won't accidentally rotate. Balance is great, and it has plenty of power for any light to medium duty metalworking task - rebar cutoff, pipe/tube cutting, plate grinding, etc. The paddle switch is simple, and does not require much force to hold it On. My hands don't feel fatigued after extended use.

        Great grinder by Milwaukee
        I’m always looking to expand my toolbox and I’ve recently found myself in need of a grinder for a few projects involving cutting rebar. I also needed a grinder for some projects involving welding. I’m new to both of these types of projects but I wanted to have the proper tool. Since I already have several Milwaukee M18 tools, including the batteries, I decided to try this Milwaukee M18 18V Lithium-Ion Brushless Cordless 4-1/2 in./5 in. Grinder w/Paddle Switch (Tool-Only). The tool arrives with the side handle detached but it is simply a matter of screwing it in on either side of the tool depending on what your dominant hand is. When I received it, I bought a cut-off disc and got to work cutting some half inch rebar. This grinder had plenty of power and made cutting the rebar easy. Previously I had been awkwardly cutting the rebar with a reciprocating saw and this was a good improvement. I’m very happy with the performance of this grinder and I would definitely recommend it.

          Powerful charger
          The Milwaukee M18/M12 charger is small but mighty. Packs a pinch. Great for all my battery Milwaukee tools!

          You just can't beat the milwaukee m18 batteries and tools
          I have been using these a while and these 5.0 batteries will get a lot of work done on a charge. I use them in a variety of tools from drills to saws to leaf blower to weed eater etc and they are work horses. I love that every one has a charge indicator - not just the higher AH batteries like some vendors. I hav e several chargers on a charging station and a variety of batteries on tap so even if I'm working the whole long day with them I'm never at a loss for power. These 5.0's are a good size for a drill or impact driver although sometimes I like the smaller ones for light jobs. But where I'm going to be doing more these is the ones I reach for. My drill is probably the most heavily used of all my milwaukee tools so I use this size battery a lot.

            Great battery and charger. The Milwaukee M18 5.0 battery lasts a long time between charges and charger also charges very quickly. This charger can also charge the M12 battery.

            I purchased a combo set for Milwaukee and this was included. The Milwaukee 90-degree impact set is phenomenal and I use it every day at work and at home. The battery and charger are excellent only drawback is the humming noise the charger makes. I would recommend this to anyone!

            Saw was light weight and easy to use. I would recommend having a second battery for backup if planning on using for more than an hour at a time.

            I was hesitant to buy this because of the bad reviews about the battery, but I have had no problem with the battery or the impact so far. I am an auto mechanic and in my opinion for a 3/8 it has a lot of torque. Would strongly recommend.
