          Will A SDS Plus Bit fit a SDS Max Hammer drill
          ByJun 20, 2026
          1 Answer | 
          Answer This Question

          SDS PLUS bits use a smaller 10mm shank while SDS MAX bits use a larger 18mm shank. The two shanks are incompatible with each other. Milwaukee however does carry an SDS MAX to PLUS adapter (48-03-3025) to address this.

          By|Jun 21, 2026


            Does it have a spin only mode
            ByJun 1, 2026
            1 Answer | 
            Answer This Question

            This unit has two modes: rotary hammer and hammer only. Like many SDS MAX units, there is no rotary (rotation) only mode. Most SDS PLUS units however have all three modes but usually have significantly less impact force as well.

              What is the difference between the 5/8" the 1 " and the 1 1/8" drills
              ByMay 27, 2026
              1 Answer | 
              Answer This Question

              Hey Rick. The M18 FUEL™ SDS-Plus Rotary Hammer lineup offers these three main sizes: 5/8", 1", and 1-1/8" — and the difference comes down to drilling capacity, impact energy, and ideal application.

                Good tool. However, the insert plastic is made from melting plastic. Use it only once and the tool is done.

                  Compact and powerful.Use it for wall opening for a window.Used it for straight 5 hrs,the drill was a bit hot but its keeps going.Demolished the 11" concrete wall easy. Battery life depends on what mode you're using. Overall very satisfied!

                    Best 1inch Rotary Hammer

                      Out drills many SDS MAX!
                      This hits really hard. Impressive power and run time drilling 1-1/4” holes. The light is very bright which helps. I’m an electrician so the work space is often dark until I’m finished. Decent chipping power as well for an sds plus. Overall very impressive. The anti vibration handle is great. Comes with an adjustable depth guage and a side handle as well

                        YOU NEED THIS ON YOUR WORK SITE!
                        What a solid kit this is. Comes with a large heavy duty case to protect your investment. It has two strong snap closures and a padlock hole for locking the case. In addition to the drill itself, this kit includes two 6.0 amp lithium batteries, a rapid charger for both M18 and M12 batteries, a tube of lube for the base of the drill bit, an adjustable support handle for the front of the drill, a depth gauge, and an owner's manual. This drill is rated to be able to drill 25 - 3/4" x 4" holes on each battery. With 2 batteries, that's 50 holes. With the quick charger, by the time one battery is drained, the next is ready to go again. A needed safety feature: when you're drilling and hit something that binds the bit rotation, the Auto stop/anti kick back feature saves wrists. While going hard the brushless motor runs smooth and keeps the heat low which saves the motor and allows you to run all day. The in-line motor and length helps relieve stress on your back when drilling vertically. A nice shock absorber on the D handle reduces vibration; again to make running all day easier. Tougher, better, and 6 lbs lighter than the comparable DeWALT Max model. With One-key capability you can keep track of your investment. Three modes of operation. Normal drilling, hammer, and rotary hammer. SDS+ chuck accepts any SDS+ accessories. An LED light illuminates the drilling surface. The underside of the drill has a solid rail for sliding on the optional Hammervac dust extractor. What's not to love about this kit? Milwaukee thought of everything that you would need to get started drilling massive holes in tough material and a lot of them. The SDS Plus chuck makes it easy to swap out drill bits in seconds. The two heavy duty batteries allow you to run all day. I mean it's a little expensive, but you get what you pay for. A real quality product with an excellent warranty.

                        2nd time buyer here!
                        This is a great rotary hammer. The 1" bit options are perfect for residential service work and light enough to stock on a service vehicle. This is my favorite drill for 5/8 wall anchors, since it retains the ability to effortlessly core a 2-1/2" service entry. Harry didn't always have a rotary hammer. He paid for his eduction with a hammer drill, and now his wrists hurt. People like working for Harry.

                          If you need to drill into concrete, or take up tiles, this is the answer!
                          I needed to drill holes for screws in my foundation wall to secure the whole-house water filtration system that the previous owner installed with nails. I had an SDS Plus drill bit but just a regular drill. Persistence finally paid off and I was able to get the job done. Today, I went back to see how much difference there would be using the right tool for the job. What a difference! The bit went right in without my having to push hard on the drill. Yes – this was overkill for a small job but the job that this tool is designed for is going to be much easier because the power that this drill has is awesome! I didn’t experience anything that would bind the bit but the Autostop Kickback Control feature prevents over-rotation that can cause an injury. I’ve experienced kickback in other instances and not having to worry about it with this drill is great. The in-line D-Handle design is great for accessing tight spaces and this tool feels solid and is very well-balanced. The side handle helps with balance and the depth gauge eliminates the need for tape around the bit - so you don’t drill deeper than intended. The AVS Anti-Vibration System reduces helps to make this drill comfortable to use. There are 3 modes of operation: Rotary Hammer, Hammer Only, Rotary Only. In other words, it does it all. The power specs are as follows: POWERSTATE™ Brushless Motor delivers 3.65 ft-lbs of impact energy, 810 RPM, and 4,650 BPM. This tool is also supported by the Milwaukee ONE-KEY system which allows for tracking and management of the tool. This is a tool-only item. No battery or charger comes with it. Be sure to get a set of SDS Plus drill bits if you don't already have a set! You should also seriously consider the Hammervac dust collector that is made for this tool. You'll really be glad that you did! I have no problem rating this tool highly!

                          This tool is beautiful
                          I'm reviewing this Milwaukee M18 fuel one key 18 V lithium brushless cordless 1 1/4 inch SDS plus D-handle rotary hammer (tool only). I've mostly used hammer drills in the past with 3/8" chucks for putting in lag Shields and such. We rented A corded SDS plus drill at work for drilling a couple 1" holes true 12" of concrete and was amazed at the speed. So when I had a chance to get this drill I wanted it. And I'm not at all disappointed. Tool came packed very well. When I used a 3/16" drill in concrete with light pressure it drilled 5 inches deep in 2-3 seconds as fast as I pushed it. I switched to a 1/2 " drill and went 2" in 4-5 seconds. Then I tried a1" carbide core bit and cut 1/2" deep in 2/3 seconds I stopped there I didn't need a 1" hole just wanted to test it. Side handle has a built-in stop rod for setting depth of holes. With D-Handle style your pressure is in line with hole so may have less fatigue to wrists. I am very impressed with this Milwaukee tool.

                          Excellent anti-thief protection
                          A very powerful hammer drill can bore several 3/4 x 4-inch holes at a faster phase without having to replenish battery life ( using an XC high-output 6.0 ah lithium battery from Milwaukee) as well as fatigue to complete your job. This product has a security tracking device in case of being lost or misplaced. The owner must download the apps and register the product and other Milwaukee products that have a "One-Key" feature, which is available at most latest Milwaukee tools. Other features are "Autostop" kickback control for safe operation and so much more that can be found on all technologically advanced Milwaukee tools.
