About This Product

The MILWAUKEE® M18™ Brushless 4-1/2” / 5” Cut-Off Grinder delivers power and runtime while maintaining a compact size. Milwaukee built and optimized the 11,000-rpm brushless motor specifically for cutting and surfacing applications. The Brushless Grinder, paired with built-in REDLINK™ power tool technology and REDLITHIUM™ batteries, efficiently delivers power and provides longer battery life, resulting in up to 80 cuts in ½” rebar. With the XC5.0 battery attached, the Brushless Grinder's body weighs only 4.6 lbs and measures 12.25" in length. The Brushless Grinder includes an electronic clutch for kickback protection and overload protection to maximize motor life. The 5/8”-11 spindle and tool-free guard adjustments ensure faster adjustments and less downtime while fully compatible with the most common grinder accessories in the market. The compact and lightweight build allows for excellent control and comfort. The all-metal gear case ensures that the Brushless Grinder is built to last and gets the job done every time.

Q:What cut off wheel goes best with this?
by|Apr 18, 2024
1 Answer
Answer This Question

A:  Hi Rodz, the type of cut off wheel depends on the application you are looking to complete. The M18 Brushless Grinder has a 5/8 in. to 11 in. spindle for use with common grinding accessories. - Milwaukee Tool Social Team

        Q:Will the Milwaukee 3.0 high output batteries power this grinder for light duty work? Thanks for your help. Vince
        by|Jan 6, 2024
        1 Answer
        Answer This Question

        A:  Yes it will. I use a 3.0 battery on mine so it’s a little lighter than the 5.0 battery. I even use the 2.0 but it doesn’t last long.

        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 For DIY
        Simple to assemble; just attach the guard and screw on the handle. The handle can easily be moved to the other side; for right-hand or left-hand use. The guard can be rotated; to shield you whichever way you are holding the grinder. It has an add-on plastic guard; for Type 1 use (see pic). The Brushless motor works great, when letting the wheel do the cutting, but if you plan on ‘leaning into it’, you may want to get the Fuel Version (Model 2880-20). The ‘REDLINK Intelligence’ will shut it off if overdriven. It has a 5/8” – 11 Spindle. If you are screwing on something (e.g. a wire brush) get 5/8”. If you are using something with a hole (e.g. a cutting wheel) get 7/8”. No wheels or brushes are included. I decide to order the Milwaukee 4.5” x 0.045 in. x 7/8 in. Cut-Off Wheel Type 27 (Model 49-94-4505). Bought the 2 pack; since it was a better deal. I prefer a Grinder, over a Reciprocating Saw, for cutting anything that may bounce around with the saw’s blade. This Grinder sure sped up taking down an old chain-link fence (see pic).

          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.

          The job site standard
          An excellent grinder. Extremely reliable and powerful with a good battery. I like the paddle especially when using a chain disc. Kind of scary without it.
