Craftsman Cordless 4-1/2-in Small Angle Grinder Kit Review
Craftsman's Cordless Small Angle Grinder, model CMCG400M1, is a versatile and robust addition to any DIY enthusiast or professional's toolkit. Having spent considerable time with this tool, I feel confident in sharing my insights and experiences.
First impressions matter, and this grinder does not disappoint. The high-performance motor, boasting a no-load speed of 8,500 RPM, immediately shows its capability. Whether you're grinding metal, cutting tiles, or performing quick touch-ups, the motor delivers consistent and reliable power. I found this particularly useful when working on a metal skirting project, where the grinder effortlessly handled continuous use without faltering.
The cast metal gear housing is a thoughtful design element, ensuring efficient heat dissipation during extended use. This feature came in handy during prolonged sessions, as the tool remained cool to the touch, allowing for uninterrupted work. The grinder's ergonomic design, with a contoured over-molded handle, provides a comfortable grip, reducing fatigue during extended use. The 3-position handle adds a layer of versatility, making it easy to maneuver the tool in various positions, whether left-handed or right-handed.
One standout feature is the tool-free guard position adjustment. This allows for quick and easy adjustments, enhancing application flexibility. I appreciated this when switching between different tasks, as it saved time and effort. The spindle lock is another convenient feature, simplifying disc and brush changes. However, I did notice that the spanner wrench included for changing discs lacks onboard storage, which can be a minor inconvenience.
The grinder's cordless nature is a significant advantage, offering freedom from power cords and extension cables. Powered by a 20V MAX Lithium-Ion battery, the tool delivers impressive performance. However, the battery life can vary depending on the task. For light to medium-duty tasks, the included 4Ah battery suffices. But for more demanding jobs, I recommend investing in higher capacity batteries, such as 6Ah or 9Ah, to ensure longer run times without frequent recharges.
One area that could use improvement is the safety lock switch. During my use, I encountered occasional issues with the lock switch not engaging consistently. While this did not pose a significant problem, it is something to be mindful of, especially during tasks that require precision and control.
The grinder's performance is commendable, but it's essential to set realistic expectations. It excels in small to medium-duty tasks, such as grinding rust off metal, cutting through light gauge sheet metal, and sharpening lawnmower blades. For heavy-duty applications, a corded model might be more suitable due to the limitations of battery power.
In terms of build quality, the grinder feels sturdy and well-made. The materials used do not feel cheap, and the overall construction inspires confidence. The tool's weight, at 9.4 pounds, is manageable and balanced, making it easy to handle during various tasks. The 5/8-11 mounting arbor ensures compatibility with a wide range of angle grinder accessories, adding to its versatility.
One notable aspect of this grinder is its price point. Compared to other cordless grinders on the market, it offers excellent value for money. Craftsman's decision to include a battery and charger in the kit is a welcome addition, making it a cost-effective choice for those new to the Craftsman platform. For existing Craftsman users, the grinder seamlessly integrates with other 20V MAX tools, adding to its appeal.
Despite its many strengths, the grinder is not without its flaws. The lack of a trigger lock for continuous operation is a notable omission. This feature would have been particularly useful for tasks that require prolonged use, as it would reduce hand fatigue. Additionally, the touchy trigger can be a minor annoyance, as it requires a firm and quick press to engage properly.
Overall, the Craftsman Cordless Small Angle Grinder is a solid performer for its price range. It offers a good balance of power, versatility, and convenience, making it suitable for a wide range of applications. While it may not replace a corded grinder for heavy-duty tasks, it excels in portability and ease of use for smaller jobs.
I would recommend this tool for DIY enthusiasts, homeowners, and professionals who need a reliable cordless grinder for light to medium-duty tasks. Its strengths outweigh its minor drawbacks, and the overall performance and value make it a worthwhile investment. If you're looking for a versatile and capable cordless grinder, the Craftsman CMCG400M1 is a commendable choice.
