      Putting it through the paces
      In 4 days of work since purchase, this drill has drilled over 400 holes in masonry for furring install using 3/16" tapcons. Granted, a small diameter masonry bit (5/32), but still a good test on extremely hard, 60 plus year old concrete block.

        Super hammer drill/driver
        I am very impressed with the 1/2 inch hammer drill / driver from Milwaukee. This tool handles very well, is quite powerful and reliable on the job site. I have used this for a variety of applications and all types of weather conditions (snow, rain, heat, etc.) and this tool is definitely one beast of burden. The tool is easy to clean and maintain. It works on the m18 battery, has two speeds, and can alternate between drilling, fastening and hammer drilling functions for a variety of uses.

          Really happy with this drill driver so far. It's an M18 so there's plenty of power and the batteries last longer. I tested it out drilling and driving screws into sheetrock as well as drilling into concrete. It worked flawlessly. When driving screws, the clutch has the ability to slip so that I don't drive the screw too deep or damage the screw head by overtorque. Having the attachable handle helps with tough jobs like concrete hammer drilling. The LED light is at the bottom so my hands don't block the light while I'm working. After giving the manual a quick read, utilizing the various settings was easy. I'll be using this tool for many a tough job to come. Another great item from Milwaukee!

          Another Great Product by Milwaukee!
          This Milwaukee M18 FUEL 1/2 inch Hammer Drill Driver runs on the Milwaukee 18v lithium ion M18 platform. This Drill driver works fantastic. It feels smoother that my older drill driver. I like the fact that you get that handle that gives you great leverage when you need it. It comes with 2 batteries and a charger also. The grip is very comfortable, you won't get fatigued when using this hammer drill driver.

          This is a powerful, full-featured and compact 1/2-inch drill/driver tool kit
          This review is for the new Milwaukee Cat. No. 2904-22, 1/2-inch Hammer Drill/Driver Kit. This kit includes the drill/driver with removable side handle, two 5 Ahr REDLITHIUM batteries, battery charger, tough plastic carrying case and operators manuals. This new drill driver is quite compact at only 7 inches front-to-back and 10 inches high, including installed battery. It weighs a relatively light 4 pounds, 13-1/2 ounces with a supplied battery installed. It has an all metal chuck. This drill/driver has an LED light that illuminates the work area from near the base of the handle when the motor is activated. I have a similar Milwaukee 1/2-inch hammer drill/driver kit, Cat. 2704-20. Welcome changes for this new tool vs. my older Milwaukee 2704 include the much improved illumination, lighter weight and more compact size, front-to-back. The new LED light mount location is better and the light color whiter than the older tool that has the a less effective blue color. This new model has an enhanced safety feature provided by the AUTOSTOP control. What this feature does is to stop the tool from excessive rotation in either direction if a cutting tool like a hole saw suddenly jambs during use, not uncommon when cutting large holes with a hole saw or with a large diameter spade bit. If this interlock is activated, an indicator light near the base of the handle flashes. I like this feature a lot as I have had instances of a jamb that caused wrist sprain, What really surprised me is the high power and torque of this relatively compact drill/driver. The tool arrived with batteries having an estimated 40% charge. It took about 1-1/2 hours to charge each of them fully. I have used this kit so far for cutting 2-1/8-inch diameter holes in hardwood doors to mount hardware, for hammer drilling 3/8-inch diameter 3-inch deep holes in a poured concrete wall to mount a hose reel and for hole-sawing 3-inch diameter holes in fir floor joists to install a plumbing pipe. It worked flawlessly for each of these projects. The tool and the charger have a five-year limited warranty. This tool kit is a high quality, much-appreciated addition to my handyman-inspired tool collection. I expect to reach for it often.

          Great drill
          My kids are getting older and I need more drills to fix stuff they break and for the to do more projects. I have had these drills for a while now. They hold up well and are nice to use. The new drill came with a automatic stop if the bit gets caught. A nice feature so no one gets hurt. There is no longer a bit holder included. The mounting hold is there if you really need the bit holder. I received this Milwaukee M18 FUEL 18V Lithium-Ion Brushless Cordless 1/2 in. Hammer Drill/Driver for free to write this review.

          Powerful hammer drill
          I received the M18 Fuel hammer drill in good condition. This is the newest Fuel model. It is claimed to be the most compact and powerful among the major brands. It has two speeds, and it is made in China. I tried the drill in various modes and it functions well. The chuck appears to be made out of steel. There is a belt clip on one side which could be put on the other. The grip is comfortable with rubber over mold. The sides of the tool are protected by small rubber nubs. An offset LED lights the work area and goes out 10 seconds after releasing the trigger. In use, this is a very powerful beast, suitable for the most challenging jobs. I found it to be loud and the tool vibrates a little more than I expected, compared to other hammer drills I have. Included is a sturdy forward grip which has no rubber over molding. It attaches onto the drill using included metal clamps. Since I just received this tool, I can’t speak to durability, but my experience with previous Milwaukee tools tells me that it should last a long time and provide good service.
