DeWalt 4-1/2 in. - 5 in. Trigger Switch Grinder with No Lock-On

As someone who frequently works with metal and wood, having a reliable and powerful angle grinder is crucial to getting the job done efficiently. Recently, I had the opportunity to use the DeWalt 4-1/2 in. - 5 in. Trigger Switch Grinder with No Lock-On (model DWE43115N), and it has quickly become a valuable addition to my toolkit. This review will explore my experience with this tool, highlighting its performance, features, and overall usability.

Performance and Power

Right out of the box, the DeWalt grinder impresses with its robust build quality. The motor operates at a blistering 11,000 rpm, providing ample power for a wide range of tasks. Whether I was grinding down metal welds or sanding weathered wood, the grinder performed exceptionally well. The high amperage of 13 amps allows you to lean into the tool without the fear of it bogging down or overheating.

One of the standout features is the Anti-Rotation E-CLUTCH® System. This safety mechanism activates quickly when a pinch or stall occurs, stopping the motor almost instantaneously. This not only prevents potential damage to the tool but also adds a layer of safety for the user. During one of my metal grinding sessions, the clutch activated when the wheel got pinched in a tight spot. The quick response of the E-CLUTCH® System was reassuring and prevented what could have been a damaging situation.

Ease of Use

The trigger switch design is both ergonomic and functional. Unlike some other grinders, the DeWalt's trigger switch is easy to grip and does not cause fatigue, even during extended use. Initially, I thought I would need the trigger lock feature, but the comfortable design of the trigger made continuous operation hassle-free. The tool-less wheel guard adjustment is another practical feature. It allows for quick and easy adjustments without the need for additional tools, which is a significant time-saver.

The Power Loss Reset® feature is another thoughtful addition. This mechanism prevents the tool from restarting after a power cut while it is still in the 'on' position. It's a small but crucial safety measure, especially in a busy workshop environment where power interruptions can occur unexpectedly.

Dust Management

Working with an angle grinder can generate a lot of dust and debris, which can affect the tool's performance over time. The DeWalt grinder comes equipped with a Dust Ejection System that helps maintain performance by removing harmful particles from the air intake. During my use, I noticed a significant reduction in the amount of dust clogging the tool, which contributed to smoother and more consistent operation.

Versatility

One of the most impressive aspects of this grinder is its versatility. I used it for a variety of tasks, from heavy-duty metal grinding to more delicate wood sanding. The grinder handled everything I threw at it with ease. For wood sanding, I used 50 and 80 grit sanding discs, and the results were impressive. The grinder quickly stripped away old stain and weathered wood, leaving a smooth surface ready for refinishing.

The tool's ability to handle different types of discs and attachments adds to its versatility. Whether you're using a diamond metal cutting wheel for gutter work or a wool buffing pad for boat maintenance, the DeWalt grinder adapts seamlessly. The spindle size of 5/8-11 inches is standard, making it easy to find compatible accessories.

Durability and Build Quality

DeWalt is known for its durable and well-crafted tools, and this grinder is no exception. The construction feels solid and dependable, with attention to detail evident in the seams and finish. Despite its power, the grinder is well-balanced and easy to control, even in challenging positions like working upside down under a vehicle. The heavy-duty cord and comfortable grip further enhance the tool's usability.

Minor Drawbacks

No tool is perfect, and the DeWalt grinder has a few minor drawbacks. The guard, while functional, can be a bit shaky and not as user-friendly to adjust or remount as I would like. Additionally, the grinder does not come with any accessories aside from an allen wrench. While this isn't a deal-breaker, it would have been nice to have a few basic accessories included, especially given the tool's price point.

Final Thoughts

Overall, the DeWalt 4-1/2 in. - 5 in. Trigger Switch Grinder with No Lock-On is a powerful, versatile, and well-built tool that delivers on its promises. Its high performance, safety features, and ease of use make it a valuable addition to any workshop. Despite a few minor drawbacks, the grinder's robust construction and thoughtful design make it a tool you can rely on for years to come.

I would highly recommend this grinder to both professionals and serious DIY enthusiasts. Its combination of power, versatility, and durability ensures that it can handle a wide range of tasks with ease. Whether you're grinding metal, sanding wood, or cutting through tough materials, the DeWalt grinder is up to the challenge.
