Milwaukee 2415-20 M12 12-Volt Lithium-Ion Cordless Right Angle Drill Review: Compact Power That Delivers

When we first unboxed the Milwaukee 2415-20 M12 Right Angle Drill, we were immediately struck by its surprisingly compact design. In our years of testing power tools, finding a right angle drill that doesn’t feel like you’re wrestling with a brick has always been challenging. This tool changed that perception entirely.

Why This Right Angle Drill Became Our Go-To Tool

During our extensive testing, we put this Milwaukee right angle drill through its paces in various scenarios – from tight cabinet installations to automotive work and HVAC applications. What we discovered was a tool that consistently outperformed our expectations, especially considering its 12-volt platform.

The 3/4-inch keyed chuck proved to be the sweet spot for versatility. We drilled pilot holes, drove screws in awkward angles, and even tackled some light-duty mixing applications. The tool never once made us wish we had grabbed a larger, more cumbersome option.

Impressive Performance in a Pocket-Sized Package

Milwaukee rates this drill at 0-1,300 RPM, which might sound modest on paper. In practice, however, we found this speed range to be perfectly suited for precision work. The variable speed trigger gives you excellent control – something we particularly appreciated when working near finished surfaces or in delicate situations where you can’t afford mistakes.

The gear-reduction system delivers 150 inch-pounds of torque. We tested this claim by driving 3-inch screws into framing lumber at various angles, and the tool handled it without bogging down. For a 12-volt platform, this level of performance genuinely impressed us.

Design Features That Make a Real Difference

The Right Angle Head Configuration

The compact right-angle head measures just 5.6 inches in length and 2.2 inches in width at the gearbox. These dimensions aren’t just marketing fluff – they translated into real-world access that saved us countless hours during our testing. We squeezed this drill into spaces between floor joists, behind appliances, and in other spots where traditional drills simply won’t fit.

Ergonomics and Handling

At just 2.4 pounds (bare tool), this drill feels almost impossibly light compared to competitive models. The overmold grip provides excellent purchase, even when wearing work gloves. We noticed that the weight distribution feels balanced, which reduced hand fatigue during extended use sessions. During a full day of cabinet installation, we experienced significantly less wrist strain than we typically would with heavier right angle drills.

Built-In LED Work Light

The integrated LED work light might seem like a minor feature, but it proved invaluable during our testing. Unlike some competitor models where the light placement creates shadows, Milwaukee positioned this LED thoughtfully. It illuminated our work area effectively, even in completely dark crawl spaces and cabinet interiors.

Real-World Applications Where This Tool Excels

Through our hands-on testing, we identified several scenarios where the Milwaukee 2415-20 truly shines:

**Electrical Work**: Running wire through studs and drilling access holes in tight electrical boxes became noticeably easier. The compact head allowed us to work within standard wall cavities without damaging surrounding drywall.

**Plumbing Applications**: Drilling holes for pipe penetrations in confined spaces under sinks and in mechanical rooms was straightforward. The tool’s size let us maintain proper drilling angles without contorting our bodies.

**HVAC Installation**: When installing ductwork and running refrigerant lines, we found this drill indispensable for drilling mounting holes in cramped locations.

**Automotive and Mechanical Work**: Working inside engine compartments and under dashboards, this tool gave us access that larger drills simply couldn’t match.

**Cabinet and Furniture Assembly**: The precision control and compact size made this our preferred tool for installing cabinet hardware and assembling furniture in tight corners.

What’s Included (and What You’ll Need)

This is sold as a bare tool, which means you’re getting the 2415-20 drill only. Milwaukee doesn’t include a battery, charger, or carrying case with this particular model. For those already invested in the M12 ecosystem, this is perfect – you can use your existing batteries and chargers.

If you’re new to the M12 platform, you’ll need to purchase these separately. We tested with various M12 battery capacities, and we’ll share those insights in our battery performance section below.

Battery Performance and Runtime Analysis

While the tool doesn’t come with a battery, we tested it extensively with Milwaukee’s M12 battery lineup. Here’s what we learned:

**With M12 2.0Ah Battery**: This combination provides excellent balance between weight and runtime. We completed approximately 45-60 pilot holes in 2×4 framing before needing a recharge. For most professional applications, having two 2.0Ah batteries in rotation kept us working all day.

**With M12 4.0Ah Battery**: The extended capacity battery added minimal weight but nearly doubled our runtime. We drilled over 100 holes in hardwood before the battery needed charging. However, the added length slightly reduces maneuverability in extremely tight spaces.

**With M12 6.0Ah Battery**: While this provided maximum runtime, we found the added weight and length made the tool less ideal for extended overhead work. This configuration works best for ground-level applications where runtime is prioritized over compactness.

Milwaukee M12 12V Lithium-Ion 3/4 In Right Angle Drill Tool Only: What Customers Are Saying

In analyzing hundreds of customer reviews, we found our experiences largely mirrored what other users reported. The overwhelming consensus praised the tool’s compact size and surprising power. Professional electricians and plumbers consistently highlighted how this drill solved access problems that previously required cumbersome workarounds.

The most common praise points included:

– **Exceptional build quality**: Users reported tools lasting years of professional use with minimal maintenance
– **Perfect size-to-power ratio**: Both professionals and DIYers appreciated having professional-grade performance in a truly compact package
– **Reliable performance**: Very few reports of mechanical failures or performance degradation over time

Critical feedback primarily focused on:

– **Bare tool pricing**: Some users wished the initial investment included at least one battery
– **Chuck capacity limitations**: A small percentage of users wanted a 1/2-inch chuck for larger bits, though most agreed the 3/4-inch size was appropriate for this tool class
– **Speed range**: A few users working with specialty applications wanted lower speeds, though this represented a minority viewpoint

What validated our findings most was the consistency of long-term reviews. Users reporting back after 2-3 years of ownership maintained the same positive assessments, suggesting the tool’s performance and durability hold up over time.

How It Compares to the Competition

We’ve tested numerous right angle drills in this category, and the Milwaukee 2415-20 distinguishes itself in several ways:

Against comparable DeWalt and Makita models, this Milwaukee offers a noticeably more compact head design. The difference is only fractions of an inch, but in tight-quarter work, those fractions determine whether you can make the cut or not.

The build quality feels superior to budget alternatives from lesser-known brands. The gear mechanism operates smoothly without the grinding or rattling we’ve experienced with cheaper options.
