We’ve all been there. You’re deep into a job—maybe it’s a transmission mount, a stubborn brake caliper bolt tucked behind the steering knuckle, or an exhaust flange nut that seems welded by rust and heat. Your standard impact wrench is too bulky, its pistol grip clashing with the frame rail. Your trusty hand ratchet fits, but you can’t get enough leverage to break the bolt free. Your knuckles are scraped, your patience is evaporating, and a 30-minute job is quickly turning into an all-afternoon ordeal. This frustrating scenario is the bane of every mechanic, technician, and serious DIYer. The inability to apply real, impactful torque in a confined space isn’t just an annoyance; it costs time, money, and can lead to stripped bolts or damaged components. This is precisely the problem that demands a specialized solution, a tool that combines raw power with an impossible-to-reach form factor.

- Right Angle Design: Compact 3/8 in. cordless wrench with 90-degree angle for tight spaces.
What to Consider Before Buying an Impact Wrench
An impact wrench is more than just a tool for spinning lug nuts; it’s a key solution for drastically reducing the time and physical effort required to loosen or tighten heavy-duty fasteners. By delivering rapid, concussive rotational blows, it generates far more torque than a standard drill or manual wrench, making it indispensable for automotive repair, construction, and heavy equipment maintenance. The main benefits are unparalleled speed, immense power for breaking loose rusted or over-torqued bolts, and a significant reduction in user fatigue. It transforms a wrestling match with a breaker bar into a simple pull of a trigger.
The ideal customer for this type of product is someone who frequently works on vehicles, machinery, or structural projects where high torque is a necessity. This includes professional auto technicians, fleet mechanics, heavy equipment operators, and dedicated home garage enthusiasts who tackle everything from suspension work to engine rebuilding. However, a high-torque impact wrench might not be suitable for those who primarily work with delicate electronics, furniture assembly, or small fasteners where precision is more important than power. For those users, a smaller impact driver or a torque-limiting screwdriver would be a more appropriate choice. The Milwaukee 2564-20 Right Angle Impact Wrench, specifically, is for the user who faces all these high-torque challenges, but with the added complication of extremely tight workspaces.
Before investing, consider these crucial points in detail:
- Dimensions & Space: The single most important factor for a right-angle tool is its profile. Measure the clearance of your most common tight-space jobs. A tool with a long body but a slim head, like the Milwaukee 2564-20, is designed to slide into gaps where traditional impact guns can’t even dream of fitting. Consider the overall length and the head height carefully.
- Capacity/Performance: Torque is king. Look for two numbers: fastening torque (how tight it can make a bolt) and nut-busting or breakaway torque (its power to loosen a stuck bolt). The Milwaukee 2564-20 Right Angle Impact Wrench boasts an impressive 220 ft-lbs of breakaway torque, which is a critical metric for repair work. Also, consider the impacts per minute (IPM) and rotations per minute (RPM) for overall speed.
- Materials & Durability: A tool that lives in a garage or on a job site will be dropped, covered in oil, and generally abused. Look for a robust housing, often a combination of reinforced polymer and metal. The internal mechanism should be made of hardened or alloy steel to withstand the immense forces generated by the impact action. Milwaukee’s reputation for durability is built on using these premium materials.
- Ease of Use & Maintenance: Cordless is the standard for convenience, so evaluate the battery platform. Do you already own tools from that brand? Consider the tool’s weight and balance; a tool weighing under 3 pounds, like this one, significantly reduces fatigue during extended use. Features like a friction ring for secure socket retention and a variable-speed trigger add to the user-friendly experience. You can see its full feature set and user reviews to gauge its real-world usability.
Understanding these factors will ensure you choose a tool that not only does the job but becomes a trusted part of your workflow for years to come.

First Impressions: A Compact Beast Unboxed
Pulling the Milwaukee 2564-20 Right Angle Impact Wrench from its box, the first thing we noticed was its unique, elongated profile. It feels substantial and dense, a clear indicator of its alloy steel construction and powerful internals. At 14.5 inches long, it’s not a small tool, but its purpose isn’t to be short—it’s to be narrow. The head, where the 3/8-inch anvil is housed, is remarkably compact, designed to be the part that slips between engine components or behind suspension parts. The signature Milwaukee red and black housing feels rugged, with over-molded rubber in all the right places for a secure grip, even with greasy hands. As a “tool only” offering, it ships without a battery or charger, which is perfect for those of us already invested in the M12 ecosystem. Snapping on an M12 XC6.0 battery, the tool balances well, the weight distribution feeling natural and ready for work. Compared to a traditional cordless ratchet, it’s bulkier, but that’s because it’s an entirely different class of tool; this is a true impact wrench, not just a motorized ratchet, a fact made clear the moment you pull the trigger.
What We Like
- Unprecedented access to tight spaces where traditional impacts fail.
- Astonishing 220 ft-lbs of nut-busting torque from a 12V platform.
- Durable alloy steel construction built for professional environments.
- Lightweight design (2.8 lbs) minimizes user fatigue during long jobs.
- Part of the versatile and widely adopted M12 battery system.
Limitations
- Physical size is larger than some users might expect for a right-angle tool.
- Performance is highly dependent on the battery used (requires a high-output M12 battery for max torque).
Performance Deep Dive: Power Where It Matters Most
A tool’s true measure is its performance under pressure. We put the Milwaukee 2564-20 Right Angle Impact Wrench through a series of grueling tests in our automotive shop, tackling jobs that have historically been the source of immense frustration. From rusted exhaust manifold bolts to hidden suspension components, we wanted to see if this specialized tool could live up to its impressive on-paper specifications. The results were, in a word, transformative.
The Right-Angle Advantage: Redefining “Accessible”
The core value proposition of this tool is its shape, and it’s here that it truly excels. We immediately targeted a notorious task: removing the upper bell housing bolts on a rear-wheel-drive truck’s transmission. This is a job that typically involves a complex chain of extensions and swivel sockets, often resulting in lost torque and rounded bolt heads. With the Milwaukee 2564-20 Right Angle Impact Wrench, the game changed completely. The long, slender body allowed us to reach up and over the transmission, while the compact head fit perfectly between the firewall and the engine block. We could apply direct, impactful force exactly where it was needed. As one user aptly put it, “I can reach where I couldn’t before,” and our experience echoed this sentiment perfectly. The tool’s design eliminates the need for awkward tool combinations, preserving the full force of its impacts directly on the fastener. We found similar success with control arm bolts tucked deep inside the subframe and water pump pulleys with minimal radiator clearance. It’s not just a convenience; it’s a fundamental shift in how you can approach these challenging jobs, turning previously impossible angles into straightforward tasks. This incredible accessibility is a primary reason to check the latest price and availability of this specialty tool.
The M12 FUEL Powerhouse: Shattering 12-Volt Expectations
Let’s address the elephant in the room: 220 ft-lbs of breakaway torque from a 12-volt tool. We were skeptical, just like one user who initially thought, “the most this 12v battery powered impact… would at most net me 50 ft/ibs breakaway.” We are thrilled to report that our skepticism was entirely unfounded. This thing is a beast. To test its mettle, we used it on lug nuts that had been torqued to 140 ft-lbs and left to sit. The 2564-20, equipped with a 6.0 Ah M12 battery, hammered them off without hesitation. We then moved to a 10-year-old exhaust system, attacking flange bolts that were essentially fused with rust. After a few seconds of rattling impacts, they broke free. This is the power that truly separates it from a mere cordless ratchet. While a ratchet is great for speeding up the removal of an already-loosened bolt, this impact wrench does the hard work of breaking it free in the first place. It is critical, however, to pair it with the right battery. We confirmed the observation of a dissenting user who found it lacking power; when we tried it with a smaller 2.0 Ah battery, the performance was noticeably reduced. For maximum “nut-busting” power, a high-output M12 battery (4.0 Ah or 6.0 Ah) is not just recommended; it’s essential. When properly powered, the Milwaukee 2564-20 Right Angle Impact Wrench delivers on its promise, providing M18-level power in a far more agile M12 package. The raw strength in such a unique form factor is a feature that really sets it apart.
Built for the Trenches: Ergonomics and Durability
Power and access are useless if the tool can’t survive in a professional environment. Milwaukee’s build quality is on full display here. The alloy steel head and impact mechanism feel incredibly robust. During our testing, the tool was inevitably dropped, bumped against greasy frames, and exposed to brake cleaner and coolant with no ill effects. One user noted their tool “came in with a little chip out on the head,” and while unfortunate, it speaks to the solid metal construction that it was merely a cosmetic issue. The variable-speed paddle trigger is large and easy to feather, giving you excellent control to prevent over-tightening or cross-threading when starting a fastener. At just 2.8 pounds (without battery), the tool is remarkably light for the power it packs. We used it extensively overhead while working on a vehicle lift, and the minimal weight significantly reduced shoulder and arm fatigue compared to wrestling with a larger, pistol-grip impact in an awkward position. The 3/8-inch friction ring anvil holds sockets securely, preventing them from falling off into an engine bay, yet allows for easy changes without needing a special tool. It’s a collection of thoughtful design choices that demonstrate this tool was engineered by people who understand the daily grind of a technician. It is built not just to perform, but to endure. The combination of its lightweight design and rugged build makes it a valuable long-term investment that you can explore further for your own toolkit.
What Other Users Are Saying
The consensus among users mirrors our own findings: for the right application, this tool is a game-changer. The overwhelming majority of feedback celebrates its immense power relative to its size and 12V platform. One user’s journey from a standard Milwaukee ratchet to this impact wrench perfectly captures its appeal: they were initially skeptical of the 220 ft-lbs claim but were completely won over, calling it a “beast” that could handle most jobs. Many others echo the sentiment that it’s “so great and powerful” and has “Plenty of Power.” The theme of accessibility is also constant, with mechanics praising its ability to reach fasteners that were previously impossible without significant disassembly.
However, the feedback isn’t universally perfect. A key piece of critical feedback we found involved a user who “wanted to love this but it’s just not at all what it claims,” noting little change in power across different batteries. This highlights the crucial point we discovered in our testing: this tool is power-hungry, and its peak performance is absolutely dependent on a healthy, high-output M12 battery pack (like the XC4.0 or XC6.0). A base-level 2.0 Ah battery simply can’t deliver the current needed for maximum breakaway torque, leading to disappointing results. This feedback is relevant for potential buyers to set proper expectations about the need for a premium battery to unlock the tool’s full potential.
How Does the Milwaukee 2564-20 Compare to the Alternatives?
The Milwaukee 2564-20 Right Angle Impact Wrench occupies a specialized niche, but it’s important to understand how it stacks up against other types of impact wrenches. Depending on your primary needs—be it raw power, budget, or cordless convenience in a different form factor—one of these alternatives might be a better fit.

For decades, it has been the go-to choice for professional shops due to its incredible durability, power, and simple, reliable mechanism. It offers immense torque in a relatively compact pistol-grip package. The trade-off is its reliance on a powerful air compressor and a cumbersome air hose, which tethers you and limits portability. A technician working in a fixed bay with a robust compressed air system might prefer the IR 231C for its endless runtime and proven track record. It’s a choice for a static, high-volume workshop, whereas the Milwaukee offers ultimate freedom and portability for field work or moving around a shop.
3. DEWALT DCF913B 20V MAX 3/8 in. Cordless Impact Wrench
- VERSATILE FASTENING RANGE: Up to 250 ft-lbs of tightening torque and 400 ft-lbs of breakaway torque
- ACCESS HARD-TO-REACH WORKSPACES with its compact size
The DEWALT DCF913B is perhaps the most direct competitor in the cordless space, but with a critical difference: its form factor. This is a compact, “stubby” pistol-grip impact wrench. It’s extremely powerful and short from front to back, making it excellent for many tight spaces, but it cannot replicate the unique access of a right-angle head. A professional or DIYer already invested in the DEWALT 20V MAX battery platform would prefer this tool for general-purpose automotive work. It’s more versatile for a wider range of tasks like changing tires, but it will still be stopped by the same clearance issues that the Milwaukee 2564-20 Right Angle Impact Wrench is specifically designed to overcome.
