Questions & Answers

Is it okay to use a 5/8-11 Type 29 conical flap disk with this item (2880-20) instead of a Type 27? It seems like Home Depot only offers the Type 27 discs for the X-LOCK style grinders.
ByNov 11, 2025
1 Answer | 
Answer This Question

Yes, you can use a 5/8-11 Type 29 conical flap disk with the Milwaukee M18 FUEL 4-1/2 in./5 in. Grinder as long as it is compatible with the grinder's specifications. The grinder features a 5/8"-11 spindle, which is standard for most grinding accessories, including Type 29 flap disks. However, ensure that the disk diameter is within the 4-1/2" to 5" range specified for this tool.

      Answer This Question

      Slide the battery on and off the charger about 15-20 times. Sometimes the terminal on the battery will have a clear coat on it. This has worked for me lots of times.

              The arbor shaft hole size for the M18 FUEL 4-1/2 in./5 in. Grinder with Paddle Switch is typically 5/8"-11, which is a standard size for most grinding and cutting accessories. This ensures compatibility with a wide range of wheels and attachments.

                This grinder worked better than expected! Purchased it to take off stubborn paint that paint strippers couldn’t take off. Can’t wait to use it for other projects

                I ran grinders, wire wheels, and cutting disks all day long with good 6.0 high output batteries. Never once was waiting on batteries causing a job stop. Game changer for repair welders.

                  I have multiple plug in grinders, and had a cordless from another brand. I won’t name the other brand but this one has a higher speed and way more power! This is the one you want. Lots of power, and the speed is excellent. It is not really heavy. You will want a 5-6ah battery on it though, it can drain the small ones quick. This is to be expected from a high power, high output tooI. This grinder gets up to speed instantly. Rapid braking works great. Very ergonomic and balanced well even with larger batteries. Very happy with this addition to the Milwaukee collection. Oddly enough this one has also found a key role in the wood-shop outside of the primary metal work. If you add a 5” Velcro backer pad attachment it runs all your sandpaper. I use it to rough finish larger wood planks and beams from the sawmill. This thing will sling some sawdust and material removal is quick! I have saved a ton of time on pieces to bulky to plane and a lot of time and paper wasted on a standard orbital sander.

                  It was easy to assemble. Cut really well easy to control. Let the variable speed that it has for different jobs and different task. Home Depot ship pretty quick.

                  Heavy-duty, excellent
                  The Milwaukee M18 FUEL 18-Volt Lithium-Ion Brushless Cordless 7 in. Braking Grinder with Variable Speed and Paddle Switch (Tool-Only) I ordered just showed up and I couldn't be more impressed. It arrived in its retail package measuring 17' by 9' by 4' and weighing about 6 pounds. Upon unboxing you could tell this is a robust, heavy-duty tool. It comes with two guards, one for type 1 which is encased on both sides and another for type 27 which is just the upper side cover. The wheel you use should say which type of shield you should be using. The guards, which are 8" across, click into place and then can be easily rotated into whichever position you need. The directions were clear on how to install whichever wheel you are using and how to tighten them. The wrench used to tighten is included and is well made and will last as long as the tool. The body of the tool measures about 15" long and is about 3" wide without a shield installed. It comes with a nice, well padded rubber coated handle to ensure you have a good grip and it can be installed on either the left or right side of the tool depending on which hand is your dominant – a thoughtful feature. The handle measures 6" long to allow for good control even at the higher RPMs. The tool has 4 different speed settings and all are fast! It gives a wide range of speeds, from 5,000 (setting 1), 6,000 RPM (setting 2), 7,000RPM (setting 3) and 8,400 RPM (setting 4) to ensure you won't be underpowered. It states it has the ability to generate the equivalent of 13A of corded power. Another nice feature is it will accept wheels from 4 1/2" up to 7" in diameter. The Rapidstop brake is pretty amazing, even at the highest setting it stops the wheel spinning in just a second or two. It's night so I was unable to really put it to work but with all the playing I did with it the battery never moved in charge so it would seem you'll be able to do lots of work with one battery. I am VERY impressed with this tool and can't imagine it being underpowered for much of anything. I would highly recommend this grinder if you are looking for a serious workhorse!

                  Must have tool.
                  Milwaukee M18 FUEL 18V Lithium-Ion Brushless Cordless 4-1/2 in./5 in. Dual-Trigger Braking Grinder (Tool-Only) I have two corded grinders, but I needed to work out in the field with no access to power, so decided to get this grinder. Glad I did. It's been my go-to grinder since. Don’t know how I’ve gone all these years without it. Milwaukee makes high quality industrial rated tools, and I already have sets of M18 batteries, so this is a no-brainer for me. Having a quick stop feature is a plus. The only thing I personally don’t like is two hands operation and is in specific order, otherwise it will not start (I’m assuming because of safety). Overall, the Milwaukee M18 FUEL Angle Grinder is a reliable and efficient addition to any toolkit.

                  My new Milwaukee grinder is a game-changer! It’s powerful, cutting through metal like butter, and the cordless design offers unmatched freedom. The battery life is impressive, lasting through tough jobs without a hitch. With smooth handling and a quick-stop brake, it’s safe and efficient. Milwaukee’s quality shines—easily one of the best tools I’ve owned!

                  The MILWAUKEE M18 FUEL 4-1/2 in. / 5 in. Variable Speed Braking Angle Grinder brings a bunch of new innovations and features to my shop.
                  The MILWAUKEE M18 FUEL 4-1/2 in. / 5 in. Variable Speed Braking Angle Grinder brings a bunch of new innovations and features to my shop. Brushless motor that delivers 8,500 RPM, Padded Switch, Tool Free Guard Adjustment and Accessory Change, Electronic Clutch for Kickback Protection. When you add all of these features together along with the versatility of this Grinder being Cordless, I believe I found the perfect grinder. I have been using an older Corded Grinder in my shop and had no idea they came so far with all of the features. I just used the New Milwaukee Grinder to sharpen my Lawn Mower Blades and was impressed with how it performed. It ran smooth and the angle I used was unobstructed without having a cord hanging in the way. This tool has made it much more enjoyable and a lot safer to sharpen my Mower Blades. I like the adjustable side handle that swivels left or right with a quick pull of the spring action button on the handle. Changing the grinding wheel is made easy with a push of a button on the grinder that locks the rotation of the arbor. I Highly Recommend this Milwaukee Cordless M18 Grinder to anyone, especially someone still using an older corded grinder.
