Milwaukee M18 3650-20 Brushless Impact Driver Review Compact Power for Tight Spaces

Description

Compact and Lightweight Design

The Milwaukee 3650-20 M18 18V Brushless Cordless Compact Impact Driver caught my attention immediately with its sleek and compact design. Measuring only 4.4 inches in length and 2.1 inches in width, it is one of the most ergonomic tools I’ve ever used. The size of this impact driver makes it incredibly easy to maneuver in tight spaces, such as under sinks or inside cabinetry. It’s also lightweight at just 1.7 pounds (tool only), which means no unnecessary strain on your wrist during prolonged use.

I’ve worked on several projects where a bulky tool just wouldn’t cut it, and this driver became my go-to. Whether you’re an experienced contractor or a DIY enthusiast, this tool’s compact form factor ensures it adapts to your needs without being cumbersome.

Performance and Torque Power

The performance on this impact driver is nothing short of impressive. With 1,700 in-lbs of torque and 0-3600 RPM, it handles most tasks with ease. Driving screws into hardwood or dealing with stubborn bolts is effortless. I used this brushless driver to assemble a deck, and it consistently delivered powerful performance without lagging.

Its variable speed control is another standout feature. The trigger is incredibly responsive, allowing me to adjust the speed based on the material I was working with. This precision control helped me avoid stripping screws or damaging surfaces—a common issue with less refined tools. The brushless motor technology not only ensures better efficiency but also promises longer tool life.

Durability and Build Quality

Milwaukee has a reputation for creating durable tools, and this impact driver is no exception. The all-metal gearcase and premium components provide the kind of professional-grade durability you’d expect from a high-end power tool. I accidentally dropped it off a ladder (oops!), but the solid build quality meant it survived without a scratch.

For someone like me who doesn’t always treat their tools gently, this level of rugged durability is a game-changer. It gives me the confidence that the tool will last through tough projects without needing constant replacement or repairs.

Key Benefits

• Compact size makes it perfect for working in confined spaces.
• Brushless motor ensures efficiency and extended lifespan.
• 1,700 in-lbs of torque delivers ample power for demanding tasks.
• Durable all-metal gearcase withstands heavy usage.
• Variable speed trigger offers precise control to prevent overdriving.

Areas for Improvement

While the Milwaukee M18 Compact Brushless Impact Driver impressed me overall, there are a few areas for improvement worth noting:

• Battery not included: It’s sold as a “tool only” option, so you’ll need to purchase the M18 battery separately if you don’t already own one.
• No LED light placement: While it does include a light, I found its positioning slightly awkward, making it less effective in really tight, shadowy spaces.
• At higher speeds, the tool can get a bit warm after extended use, though it didn’t seem to impact performance.

Competing Products

When comparing this impact driver to competitors, a few similar models from DeWalt and Makita come to mind. For instance, DeWalt’s 20V Max XR Impact Driver offers slightly higher torque, but it’s noticeably bulkier and less comfortable to use in confined areas. Makita’s compact impact driver matches Milwaukee’s size but doesn’t quite deliver on the same durability and power output.

Where Milwaukee stands out is its balance of size and performance. The M18 system compatibility with over 250+ solutions also puts it leagues ahead for those who already own other Milwaukee tools. However, DeWalt’s broader inclusion of features like better-integrated lighting might appeal to some users, especially those who work in low-light conditions frequently.

Cost Efficiency

In terms of value for money, this tool is a solid investment. While it might seem a bit pricey upfront (especially since the battery and charger aren’t included), the performance and durability more than justify the cost. For professionals or serious DIYers, the longevity of the brushless motor and the robust build quality make this tool a smart spending choice. It’s one of those tools where you pay once and reap the benefits for years.

If you already own Milwaukee’s M18 batteries, this tool becomes an even easier pick. It seamlessly integrates into the M18 ecosystem, saving you from constantly switching between brands or buying redundant chargers and batteries.

Good Aspects

• Compact and lightweight, perfect for tight spots.
• High torque and speed deliver excellent results on tough materials.
• Responsive variable speed trigger for precise control.
• Part of the M18 system, compatible with a wide range of tools.
• Durable construction ensures longevity even under heavy use.

Weaknesses

• Battery and charger need to be purchased separately.
• LED light placement could be improved for better visibility.
• Can become warm with extended use at maximum power.

This impact driver is an incredibly versatile tool that excels in both power and usability. While it has minor flaws, they pale in comparison to its key strengths, making it an excellent addition to any toolkit.
