Milwaukee and DeWALT are known for making high-quality tools that handle almost any job. Milwaukee brings serious torque and great battery power, while DeWALT is all about durability and user-friendly designs. How do their impact wrenches compare? With so many options from both brands, knowing which one is right for you can be tricky. 

Milwaukee impact wrenches

Milwaukee impact wrenches are known for packing a serious punch, with torque levels ranging from 600 to over 1,000 ft-lbs, making them perfect for heavy-duty tasks. One of the standout features across their models is the brushless motor technology, which boosts efficiency and extends the tool’s lifespan. Whether you’re working with the compact M12 series or the more powerful M18 lineup, Milwaukee’s tools are designed to get the job done.

Milwaukee’s big plus is its battery versatility. The M12 and M18 battery platforms work seamlessly across a range of tools, so if you’re already using one of their systems, adding an impact wrench to your collection is a no-brainer. They also offer REDLINK Plus Intelligence, which protects against overloads and overheating—a convenient feature when working in tough conditions. Plus, with their extended battery life, you can stay on the job longer without constantly recharging.

Some standout models include the Milwaukee 2967-20 M18 FUEL 18V 1/2 in High Torque Impact Wrench for serious power and the Fuel™ Stubby Impact Wrench, 12 V, 3/8″ Socket, which is great when you need something more compact but still powerful. Whether you’re working on construction, automotive, or heavy equipment tasks, Milwaukee has a wrench for you.

DeWALT impact wrenches

DeWALT impact wrenches are all about durability and ease of use, with torque levels that can easily go toe-to-toe with Milwaukee. Whether you’re tackling tough jobs or working in tight spaces, DeWALT’s focus on user-friendly, compact designs makes their tools a favorite for many. Their impact wrenches are designed to last and give you the power you need while still being comfortable to handle.

One of the best things about DeWALT is the versatility of its battery systems. Their 20V MAX and FLEXVOLT platforms allow you to power a wide range of tools, making it easy to switch between jobs without worrying about compatibility. DeWALT impact wrenches are also known for their precision wrench control, which helps you avoid over-tightening or damaging fasteners. It is especially useful when precision matters. The compact and ergonomic designs are perfect for working in tighter spaces without sacrificing power.

A couple of standout models include the DeWALT 20V MAX XR ½” Brushless Cordless High Torque Impact Wrench, which offers serious torque for bigger jobs, and the DeWALT XTreme 12V MAX Brushless ⅜” Cordless Impact Wrench for those smaller, more precise tasks. No matter the job, DeWALT’s impact wrenches are built to perform.

Milwaukee vs. DeWALT: Who has more impact?

Performance

The Milwaukee M18 FUEL ½” High Torque Impact Wrench and the DeWALT 20V MAX XR ½” High Torque Impact Wrench are heavy hitters, but there are a few differences to consider.

• Torque:
  • The Milwaukee M18 FUEL offers up to 1,100 ft-lbs of fastening torque and 1,500 ft-lbs of nut-busting torque, making it one of the most powerful options on the market.
  • The DeWALT 20V MAX XR provides 700 ft-lbs of fastening torque and 1,200 ft-lbs of breakaway torque, which is still incredibly strong and more than capable of handling most heavy-duty tasks.
• RPM (Rotations per minute):
  • Milwaukee’s M18 FUEL can deliver up to 1,750 RPM, allowing for fast, efficient work on larger projects.
  • The DeWALT 20V MAX XR offers up to 1,900 RPM, giving it a slight edge in speed, especially for repetitive tasks.
• Impact per minute (IPM):
  • Milwaukee clocks in with 2,100 IPM, providing strong and consistent impacts to loosen even the toughest bolts.
  • DeWALT leads here with 2,400 IPM, giving you a faster impact rate, which can be handy when working with stubborn fasteners.

Battery life

Both Milwaukee and DeWALT offer impressive battery life, but there are a few things to consider regarding efficiency, compatibility, and charge time.

• Milwaukee M18 FUEL:
  • Milwaukee’s M18 FUEL impact wrench is powered by M18 REDLITHIUM batteries, which deliver longer run times and faster charge times. The battery system is designed to stay cooler under heavy loads, which helps extend the tool’s and battery’s life.
  • The M18 batteries are compatible with over 200 Milwaukee tools, making it a versatile option if you already have other tools in the M18 line.
  • Charge time: Depending on the battery size, charging can take around 45-60 minutes with the standard charger.
• DeWALT 20V MAX XR:
  • DeWALT’s 20V MAX XR impact wrench uses lithium-ion batteries designed for efficiency and longevity. These batteries provide reliable power for extended periods and work with over 200 DeWALT tools in the 20V MAX lineup.
  • DeWALT’s FLEXVOLT batteries are also an option for those needing more power or flexibility across different tools.
  • Charge time: Like Milwaukee, DeWALT’s 20V MAX batteries take about 60 minutes to charge fully.

Both brands offer excellent battery compatibility across a wide range of tools, making it easy to expand your collection. However, Milwaukee’s batteries are known for running slightly cooler under pressure, while DeWALT offers more flexibility with their FLEXVOLT system.

Build and design

Both Milwaukee and DeWALT focus on durability and ergonomics, but there are some key differences.

• Milwaukee M18 FUEL:
  • Milwaukee’s impact wrench is built to be tough. Its durable frame and high-quality materials are designed to withstand heavy use on job sites.
  • At 6.4 lbs (with battery), it’s a bit heavier than DeWALT’s model, which could be a factor if you need to use the tool for extended periods.
  • The design is ergonomic, but the added weight may be noticeable over time, especially during long tasks.
• DeWALT 20V MAX XR:
  • DeWALT’s model is slightly lighter, weighing in at 5.8 lbs (with battery), which makes it a bit easier to handle, especially in tight spaces or when working overhead.
  • The standout feature is the compact and ergonomic design, making it comfortable for longer jobs without straining your arms.
  • It’s built with high-impact materials for durability, but the lighter weight doesn’t sacrifice its toughness.

Both tools are built for durability overall, but DeWALT’s lighter and more compact design may give it an edge for jobs requiring extended use or work in tight areas.
