Milwaukee Jig Saw

As someone who frequently tackles various woodworking and DIY projects, I recently had the opportunity to put the Milwaukee 2645-20 Cordless Jig Saw to the test. Milwaukee is a brand I typically trust for its robust and reliable tools, so I was eager to see if this jig saw would live up to the reputation. From its overall performance to its specific features, here’s my comprehensive take on this tool.

Design and Build Quality

First impressions matter, and the Milwaukee jig saw feels substantial right out of the box. Weighing around 6.5 lbs, it’s not the lightest tool on the market, but the weight lends it a certain stability that helps minimize vibration and kickback. The over-molded grip is comfortable, allowing for extended use without causing too much fatigue.

The tool-free shoe bevel is a standout feature for quick adjustments, with positive stops at 0/90, 15, 30, and 45 degrees. This makes it convenient to switch between different cutting angles without fumbling with additional tools. However, the lack of an LED light around the cutting area is a missed opportunity. When working in dimly lit conditions, an integrated light would have significantly improved visibility.

Blade Installation and Alignment

One of the most talked-about aspects of this jig saw is its QUIK-LOK™ blade clamp system for keyless blade changes. In theory, this should be a straightforward process, but I found the blade installation to be somewhat finicky. It took me a few tries to get the blade seated correctly. Initially, the blade would skew slightly to the right, making straight cuts a challenge. After some trial and error, I realized that pushing the blade in firmly while fully pulling back the locking mechanism helped achieve proper alignment.

Cutting Performance

When it comes to cutting power, this jig saw doesn’t disappoint. Equipped with a variable speed trigger, you can adjust the speed from 0 to 2,700 SPM, allowing for greater control depending on the material. I tested it on various substrates, including hardwood, plexiglass, and plywood, and it performed admirably across the board. The 5-position orbital cutting feature adds versatility, making it easier to handle different types of cuts, from straight lines to more intricate shapes.

However, the tool’s line of sight to the blade is somewhat obstructed by the clear plastic shield and the plastic guide attached to the foot. This makes it challenging to see your cutting line clearly, especially for finer cuts. Removing the plastic shield improved visibility but didn’t completely solve the issue.

Usability and Comfort

Comfort is a significant factor when using any power tool, and Milwaukee has done a commendable job in this department. The grip is ergonomic, and the tool feels balanced in hand, even during prolonged use. The non-marring shoe is a thoughtful addition, ensuring that work surfaces remain unscathed during operation.

The tool-free bevel adjustment and the lock feature are both convenient, allowing for quick and easy changes without interrupting workflow. However, the jig saw’s weight can be a double-edged sword. While it adds stability, it also makes the tool somewhat cumbersome for extended overhead or vertical cuts.

Battery Life and Compatibility

The 2645-20 runs on Milwaukee’s M18 battery system, which is known for its long battery life and quick charging times. I tested it with both a 1.5 Ah battery and a 5.0 Ah XC battery. The tool performed consistently well with both, but the 5.0 Ah battery offered extended runtime, which is beneficial for larger projects.

One issue to note is the compatibility of older M18 batteries with this tool. If you have older M18 batteries, they may not fit due to design changes in the newer models. This can be frustrating if you’re heavily invested in Milwaukee’s ecosystem and don’t want to purchase new batteries.

Pros and Cons

Pros:
- Powerful Performance: Handles a variety of materials with ease.
- Comfortable Grip: Ergonomic design for extended use.
- Tool-Free Adjustments: Quick and easy bevel and blade changes.
- Non-Marring Shoe: Protects work surfaces.
- Long Battery Life: Compatible with M18 battery system.

Cons:
- Blade Alignment Issues: Initial difficulty in seating the blade correctly.
- Poor Line of Sight: Obstructed view of the cutting line.
- Heavy: Can be cumbersome for extended use.
- Battery Compatibility: Older M18 batteries may not fit.

Conclusion

In summary, the Milwaukee 2645-20 Cordless Jig Saw is a robust and powerful tool that delivers on many fronts but falls short in a few critical areas. Its cutting performance is excellent, and it’s versatile enough to handle various materials and cutting styles. The ergonomic design and tool-free adjustments make it user-friendly, although the weight and line of sight issues can be a drawback.

Would I recommend this tool? It depends on your specific needs. If you’re looking for a powerful, durable jig saw and are willing to spend some time getting the blade alignment right, this tool could be a good fit. However, if you need a jig saw with flawless out-of-the-box performance and better visibility for intricate cuts, you might want to explore other options.

Ultimately, the Milwaukee 2645-20 has the potential to be a great tool with a few design improvements. For now, it remains a solid, if somewhat flawed, addition to any workshop.
