Those building a variety of outdoor structures are probably better served by an 18V tool. For occasional challenges, such as those when a standard drill driver is inadequate, a 12V model is acceptable. However, when choosing the best Milwaukee impact driver for your needs, experts generally recommend that performance is the focus. The latter offers higher performance, though the former tends to be a little lighter and more compact.Ī 12V impact driver is often considered a homeowner tool, while 18V models are aimed at pro users. Milwaukee produces impact drivers with 12V or 18V power. Some advanced Milwaukee impact drivers are unusual in that they offer multiple speed ranges, which provides the ability to match performance to the job being undertaken. However, it’s difficult to combine high speeds with high torque, so many impact drivers have a single speed. Revolutions per minute (rpm) is an important consideration for many lengthy tasks. Milwaukee impact drivers use a rapid 3,300 to 4,300 IMP. This action is measured in Impacts Per Minute (IPM). This action provides lots of small jolts, or impacts, thus increasing the driving force. On an impact driver, however, it’s rotary. On hammer drills used for masonry, concrete, etc., this action is in line with the direction of drilling. Milwaukee impact drivers maximize the torque effect by adding a hammer action. to 2,000 in.lbs., depending on the model. Milwaukee impact drivers vary from 450 in.lbs. Torque, or turning force, which is usually measured in inch-pounds (in.lbs.), is the amount of rotational power necessary to drive screws and bolts. The listed weight often doesn’t include the battery, which can add 1 to 2 1/2 pounds to the total weight. Milwaukee impact drivers, like most power tools, are often sold “bare” (without a battery or charger). The tendency of the 12V model to topple over can be frustrating. That said, the bulkier 18V unit stands up more easily. While both are well balanced, it makes some difference in maneuverability. The 12V battery often slides up into the handle, while the tool remains slender. The small size can be a big benefit when working in confined spaces.Īlso note that most 18V batteries are considerably larger than 12V models. However, the latest Milwaukee tools are all remarkably compact, and the difference is often slight. Historically, 12V Milwaukee impact drivers usually were smaller and lighter than their 18V counterparts. All new Milwaukee impact drivers use these more advanced brushless motors. Nothing is wrong with them, and they are a reliable, low-cost choice however, brushless motors are from 30 percent to 50 percent more efficient. Older style brush motors, originally designed for corded tools, create friction and heat that saps some of the power. The motor in any power tool affects its use of the available battery power. Improvements in cordless technology mean that all the company’s drivers can run on either 12V or 18V lithium-ion batteries. Until quite recently, Milwaukee offered a choice between corded and cordless versions of their impact drivers. The technical aspects of Milwaukee impact drivers can help potential buyers understand the key features that affect choice. On closer inspection, however, important differences exist.

However, since numerous models are available, finding the best Milwaukee impact driver isn’t always a straightforward process. These are powerful, pro-grade tools with a reputation for durability. Milwaukee has one of the most comprehensive ranges of impact drivers on the market. An impact driver delivers extra rotational force to drive the fixing home for jobs in which a standard drill driver would struggle. Impact drivers are the go-to tool when dealing with long screws and other large fasteners.
