1. DEWALT 20V MAX* Angle Grinder Tool
- Brand: DEWALT
- Manufacturer: DEWALT
The DEWALT DCG413B is a premium cordless angle grinder designed for professionals who demand reliability and advanced safety features. Its brushless motor eliminates the need for brush changes, ensuring long-term durability. The Kickback Brake and E-Switch Protection enhance user safety by stopping the wheel quickly during pinch or stall events and preventing accidental restarts after power interruptions. With a compact design and lightweight build (3.75 lbs.), this grinder is easy to maneuver and ideal for precision tasks.
During testing, the DCG413B excelled in cutting and grinding applications, delivering consistent power thanks to its 20V lithium-ion battery (sold separately). The two-stage trigger adds an extra layer of safety, making it suitable for high-risk environments. However, its relatively low maximum rotational speed of 3450 RPM limits its efficiency for heavy-duty grinding compared to corded models. The absence of included batteries raises the overall cost, but the 3-year warranty and robust build justify its premium price for professionals seeking a reliable, cordless solution.
Pros
- Advanced safety features like Kickback Brake and E-Switch Protection
- Brushless motor for long-term durability
- Lightweight and ergonomic design
- Cordless convenience for mobility
- 3-year warranty

Its 7.5-amp motor delivers 11,000 RPM, making it suitable for demanding cutting and grinding tasks. The compact design (4.2 lbs.) and slim grip circumference ensure comfortable handling during extended use. It includes a burst-protection guard for added safety and directed airflow to protect internal components from dust, enhancing tool longevity.
In performance tests, the Bosch GWS8-45 impressed with its smooth operation and consistent power output. The ergonomic design and two-position side handle improved control, especially during intricate grinding tasks. However, the corded design limits mobility, and some users may find the lock-on switch less intuitive than a standard trigger. The Service Minder brush system is a standout feature, automatically shutting off the tool when maintenance is required, ensuring reliability over time.

Its lightweight and slim design make it comfortable for extended use, while the protective cover minimizes exposure to sparks and debris during operation.
In testing, the AVID POWER grinder performed well for light-duty tasks like rust removal and polishing. However, it struggled with prolonged heavy-duty grinding due to heat buildup.

During testing, the SKIL 9295-01 provided satisfactory results for general-purpose grinding and cutting. The vibration-reducing handle reduced fatigue during extended use, though its heavier weight (4.03 lbs.) compared to similar models was noticeable.

The included arbor adapter adds flexibility for different grinding wheels, but the lack of advanced safety features and lower durability limits its appeal for professional use.
