Craftsman 4-1/2-in Brushless Cordless Small Angle Grinder

As a seasoned DIY enthusiast and professional contractor, I’ve had my fair share of encounters with various angle grinders. Recently, I got my hands on the Craftsman 4-1/2-in Brushless Cordless Small Angle Grinder (model CMCG450B), and it's safe to say that this tool has made quite an impression. Let’s dive into my experience with this versatile grinder.

First Impressions

Straight out of the box, the Craftsman grinder exudes quality. The build feels solid and well-balanced in hand, which is often not the case with many cordless tools. The first thing that stands out is the brushless motor, a feature that promises longer motor life and improved efficiency. This grinder also boasts a paddle switch, a tool-free guard, and a 3-position side handle—all designed to enhance the user experience.

Performance and Power

The heart of this grinder is its brushless motor, capable of delivering up to 11,000 RPM. I put it to the test on various materials, including metal and wood, and it performed admirably across the board. Whether I was sharpening lawnmower blades, cutting through metal pipes, or sanding wood, the grinder handled each task with ease. The power output is consistent, and I didn’t experience any noticeable drop in performance, even when using it for extended periods.

One of the standout features for me was the tool’s ability to maintain its power while operating on a 20V MAX Lithium-Ion battery. I used a 4.0Ah battery for most of my tasks, and it provided ample runtime. However, it’s worth noting that smaller batteries, like the 1.5Ah, do drain quickly, so investing in higher-capacity batteries is advisable for longer projects.

Ergonomics and Usability

Craftsman has clearly put thought into the user experience with this grinder. The paddle switch is intuitive and easy to use, making it simple to control the tool even when wearing gloves. The 3-position side handle is another great addition, offering flexibility in how you hold the tool for different tasks. This is particularly useful when working in tight spaces or at awkward angles.

The tool-free guard is a game-changer. It allows for quick and hassle-free wheel changes, which is essential when you’re switching between tasks frequently. I also appreciated the inclusion of the wrench in the side handle—a clever design choice that ensures you never misplace the tool needed for changing wheels.

Durability and Build Quality

Durability is a crucial factor for any power tool, and the Craftsman grinder doesn’t disappoint. The robust construction and high-quality materials used in its build give me confidence that this tool is built to last. I’ve used it in various environments, from my workshop to outdoor projects on my property, and it has held up exceptionally well.

Battery Life and Charging

While the performance of the grinder is commendable, battery life can be a limiting factor, especially if you’re using smaller batteries. During a project where I stripped paint off a garage door, I found that I needed multiple 4.0Ah batteries to keep the grinder running continuously. This isn’t a deal-breaker, but it’s something to be aware of if you're planning on using the tool for extended periods without access to a power source.

The batteries charge relatively quickly, and the easy-on, easy-off design makes swapping them out a breeze. However, if you’re a heavy user, I’d recommend investing in multiple batteries and fast chargers to minimize downtime.

Versatility and Applications

The Craftsman grinder is incredibly versatile. It’s equally at home in a professional workshop as it is in a DIY enthusiast’s toolbox. I’ve used it for sharpening tools, cutting metal, sanding wood, and even some light polishing work. Its compact size and cordless design make it a go-to tool for both small and large projects.

One of the most impressive aspects is how well it performs compared to corded grinders. In many cases, cordless tools sacrifice power for convenience, but that’s not the case here. The brushless motor and 20V system provide a level of performance that rivals many corded models.

Potential Drawbacks

No tool is perfect, and the Craftsman grinder is no exception. The primary drawback is the battery life when using smaller capacity batteries. If you’re planning on using this tool for heavy-duty or prolonged tasks, you’ll need to invest in higher capacity batteries, which can add to the overall cost.

Another minor gripe is the design of the brushless emblem, which feels a bit cheap. For a tool in this price range, a more durable badge or engraving would have been a nice touch. Additionally, the lack of an adjustable shoe and inclusion of a carrying bag are small oversights that could enhance the overall package.

Final Thoughts

The Craftsman 4-1/2-in Brushless Cordless Small Angle Grinder is a powerful, versatile, and well-designed tool that delivers on its promises. Its performance, build quality, and user-centric features make it an excellent addition to any toolbox. While the battery life with smaller batteries and a few minor design choices leave room for improvement, these are far outweighed by the tool’s overall capabilities.

Recommendation

I highly recommend the Craftsman grinder for both professionals and DIY enthusiasts. Its combination of power, portability, and user-friendly features make it a valuable tool for a wide range of applications. Whether you’re a seasoned contractor or a weekend warrior, this grinder is sure to meet and exceed your expectations.
