How these picks differ from Bosch
Makita 18V LXT Brushless 4-1/2 / 5-Inch Grinder
The Makita XAG09Z accepts both 4-1/2 and 5-inch wheels, whereas the Bosch model is limited to 4-1/2-inch discs. This flexibility allows you to use larger cutting or grinding discs without changing tools. It also features automatic torque adjustment for consistent performance under load. The Makita weighs 5.7 pounds, which is slightly heavier than the Bosch unit. You gain versatility in wheel size but lose some compactness. If you frequently switch between disc sizes or need 5-inch capability, this Makita is a practical upgrade. It retains the brushless motor efficiency found in the Bosch but adds broader compatibility for your projects.
DEWALT XR 4-1/2 to 5-Inch Variable Speed Grinder
This DEWALT model runs on a 20V MAX system instead of the 18V Bosch platform. It supports both 4-1/2 and 5-inch wheels, offering more disc options than the Bosch. The key difference is variable speed control, which the Bosch lacks. You can adjust the RPM to match the material you are working with. It also uses a paddle switch rather than the Bosch’s lock-on slide switch. This design may feel more familiar if you prefer paddle triggers. The tool weighs slightly more than the Bosch. If you need speed adjustment or already use 20V MAX batteries, this DEWALT provides greater control and compatibility.
DEWALT 60V MAX 4-1/2 to 6-Inch Angle Grinder
The DEWALT DCG418B operates on a 60V MAX FLEXVOLT system, delivering significantly more power than the 18V Bosch. It accepts 4-1/2, 5, and 6-inch wheels, making it the most versatile option for disc size. This tool is designed for heavy-duty tasks where the Bosch might struggle. However, it is heavier and less suitable for light, all-day grinding. It lacks the ergonomic slim grip of the Bosch. If you need maximum cutting power and already own FLEXVOLT batteries, this high-voltage option is ideal. It sacrifices portability for raw performance and broader wheel compatibility.
Makita 9564CV 4-1/2-Inch Corded Grinder
The Makita 9564CV is a corded tool, unlike the cordless Bosch. It offers continuous power without battery constraints, making it better for stationary or benchtop work. It features variable speed control, which the Bosch does not have. This allows precise speed adjustments for different materials. The corded design eliminates the need to manage batteries, but it restricts your movement to the length of the power cord. It is heavier and less portable than the Bosch. If you work in a shop with constant outlet access and need variable speed, this corded Makita is a robust alternative to the cordless Bosch.
DEWALT 20V MAX XR Variable Speed Angle Grinder
This DEWALT grinder uses a 20V MAX battery system instead of the 18V Bosch platform. It features variable speed control, allowing you to dial in the exact RPM for your task. It also supports both 4-1/2 and 5-inch wheels, offering more disc versatility than the Bosch. The paddle switch design differs from the Bosch’s slide switch, which may suit your hand preference better. It weighs 4.74 pounds, similar to the Bosch. If you need speed adjustment or already use 20V MAX batteries, this DEWALT provides enhanced control and compatibility while maintaining a brushless motor for efficiency.
DEWALT ATOMIC 4-1/2-Inch Angle Grinder
The DEWALT DCG402B is a compact, brushless-free option running on 20V MAX batteries. It is designed for tight spaces, with a shorter body than the Bosch. However, it lacks the brushless motor efficiency of the Bosch, which may affect runtime and power delivery. It only accepts 4-1/2-inch wheels, matching the Bosch in disc size limitation. It uses a paddle switch rather than the Bosch’s slide switch. If you need a smaller tool for confined areas and already own 20V MAX batteries, this DEWALT is a space-saving choice. It trades motor efficiency for a more compact form factor.
