Bosch Flexiclick vs Milwaukee M12 Fuel Installation Drill Driver Review

Milwaukee Installation Drill Driver Review

The Milwaukee M12 Fuel 4-in-1 Installation Drill Driver Kit is one of the most versatile combo kits ever made by Milwaukee for light and medium duty applications. It takes the D – design like the Festool CXS that was released 10 years earlier. The Milwaukee drill driver features a powerstate brushless motor that delivers up to 300 inch-pounds of torque at a maximum speed of 1600 RPMs. It is powered by a 12V lithium battery of the M12 Fuel RedLithium platform. This tool has a slim profile and weighs just about 2.0 pounds with battery, making it extremely light on your hand.

Milwaukee M12 fuel drill driver features

The Milwaukee multihead drill/driver has a magnetic bit storage that is in line with the handle. It holds securely the extra bits and fasteners thus saving you from having to fish the from your pocket. This ensures that you spend the most time working and not looking for bits and screws. The magnetic storage also acts as a handle and as a knuckle guard. This tool accepts all M12 batteries and has a fuel gauge on the side to indicate the battery charge level. At the front of the head, there is a built-in LED work light for lighting up dark areas. The light also makes it easy for you to do your finish job at night. The light remains on for 10 seconds after releasing the trigger to allow you to inspect your work.

Milwaukee M12 drill driver operation

As far as control is concerned, the Milwaukee installation drill driver gives you very good speed and torque control. It has a speed selection button that lets you choose between low speed and high speed. The low speed ranges from 0 – 400 RPMs while high speed ranges from 0 to 1600RPMs. In addition, the trigger provides variable speed control meaning that the harder you press the more speed and torque you get. There are also speed direction pushbuttons on the top at the rear that allow you to choose between reverse and forward. There is also a third button for locking and unlocking the device to prevent accidental turning on. The forward/reverse buttons on this tool are different from other M12 power tools in the sense that they lack tactile feedback and they are not located on the side, which feels a little bit less intuitive. The tool also features a selectable clutch that lets you choose a different clutch setting between 1 to 20.

Milwaukee drill driver accessories and adapters

The head attachments, on the other hand, also provide you more control on the tool. They let you unlock the drill/driver’s four different dedicated functions. These attachments include:

  1. 3/8″ Keyless Chuck

    The keyless chuck easily converts the tool into a 3/8 inch Milwaukee drill for light and medium duty drilling tasks. The chuck has nice deep grooves on it that give you a good grip when adjusting the jaws. With the right drill bit, the drill driver can drill holes into softwood and metal sheets. It can also be used with holesaws to drill circular holes into material when carrying out installation jobs.

  2. Offset adapter driver

    The offset simply has a 1/4 inch hex drive at the edge. It allows the tool to drive screws and other fasteners in very tight corners, making it suitable for cabinet installation jobs. The offset attachment can be rotated to 16 different positions thus increasing its versatility. It uses the quick connect mechanism that makes it extremely easy to install and change bits. However, when driving screws downwards, the tool can drop a driver bit especially if it is heavier than the magnetic force of the adapter.

  3. 1/4″ Hex Collar

    The collar adapter allows the tool to be used like a Milwaukee 1/4 inch driver. It has a quick change mechanism that makes it easy to remove and install bits. To change the bit, you only need to pull it out together with the sleeve. The bits are tightly held in place to avoid wiggling during operation.

  4. Right Angle adapter

    The right angle adapter allows the tool to be used as a right angle driver. The downside, however, is that the adapter cannot be used alone. It needs either the chuck, offset, or the collar. The right angle adapter helps to access very tight spaces that the tool head cannot access. It is suitable for driving fasteners in awkward installations and fixture works.

Verdict

The M12 Fuel Installation Drill Driver is a contractor-grade cordless tool for light and medium-duty installation works. It is a nice addition to your collection of power tools and the best solution for tight spaces in the Milwaukee line of tools. Furthermore, its battery is compatible with other M12 tools. For an electrician, technician, plumber, or carpenter, this Multihead drill driver will make light all your installation works. It holds screws and bits for you so that you can keep your hands on the job. This compact drill driver also has a belt clip for hooking it onto your toolbelt as you set up fixtures. Nevertheless, a few things about this tool might turn you off such as the position and the type of the forward/reverse buttons, lack of a bit locking mechanism on the offset head attachment, and the inability to use the angle attachment or the tool alone without other adapters. Some of these shortcomings might make you consider the Bosch Flexiclick or the Festool.

Bosch Flexiclick 5-in-1 Drill Driver Review

Bosch flexiclick features

The Bosch Flexiclick driver kit is similar in functionality to the Milwaukee Installation driver. However, there are certain differences in features that set these tools apart. For example, the Bosch drill driver is less powerful than Milwaukee as it only delivers 265 inch-pounds of torque and up to a maximum speed of 1400 RPMs. It also has a T-design whereas its counterpart takes a D-design. Bosch flexiclick gives you as much control as the Milwaukee because it has a 2-speed selector on the top and a variable speed trigger for regulating the amount of torque and speed. The reverse/forward button is located on the side and is as intuitive as in other Bosch power tools. The tactile feedback lets you feel the direction of rotation even without looking. This is a very convenient feature, especially when working in very tight spaces. However, the button can easily be snapped accidentally causing the direction to change unintentionally.

Bosch flexiclick drill driver accessories and adapters

Bosch drill driver kit also includes the same number of attachments as the Milwaukee. It has the 3/8″ keyless chuck, 1/4″ hex locking bit holder, 1/4″ offset hex, and 1/4″ right-angle adapter. The difference, however, is that Bosch can be used alone without an attachment for driving small screws and other light works. This is because the 1/4″ onboard hex has a magnet that prevents losing bits and screws. Both the offset and the collar adapter has a locking mechanism, though not as intuitive as the one on Milwaukee Hex collar. For the Bosch, you have to pull out the sleeve to install a bit, which is sometimes not possible with one hand. The angle attachment. The angle attachment does not have a bit locking mechanism but is magnetic. As far as the build is concerned, the bosch flexiclick is nice and compact but Milwaukee feels better.

Verdict

Bosch Flexiclick 5-in-1 drill driver is better than Milwaukee installation drill driver in terms of accessing very tight spaces but it delivers approximately 30 inch-pounds less torque. It is also fairly priced and delivers plenty of power for its size. However, the Flexi click lacks exciting features such as an onboard bit holder and a belt clip. Its battery also sits in very tightly making it very difficult to remove sometimes. It is a great addition to your cordless power tools more so if you have other Bosch tools and if you are DIY person.

Conclusion

Overall, if you have a tight budget, the Bosch Flexiclick drill driver kit is a great consideration. It is more suitable for DIY guys and requires less headroom with some of the attachments. It is also good for cabinet installers. On the other hand, if you want a contractor-grade multi-head driver kit, the Milwaukee installation driver is the best. It has the muscle, very quality build, and a wide array of compatible power tools. The downside of both drill drivers is that they both lack the hammering feature, so they cannot replace your hammer drill or the impact driver. They also lack a durable carry case, so you might have to purchase a custom hard plastic case to make it possible to stack with other tools in the workshop.
