How to choose the right one
-
Check power source needs
You must decide between corded and cordless operation based on your workspace. Corded models like the DEWALT 13-Amp 4-1/2 to 5-Inch Trigger Angle Grinder provide continuous power without runtime limits. They suit heavy workshop jobs where outlets are available. Cordless options offer mobility but require battery management. Choose corded for stationary tasks and cordless for site work or areas without power access.
-
Verify battery compatibility
Most listed grinders are bare tools, meaning you need existing compatible batteries. The DEWALT 20V MAX 4-1/2-Inch Brushless Paddle Grinder works with your current 20V MAX packs. If you lack batteries, select a kit like the CRAFTSMAN V20 4-1/2-Inch Angle Grinder Kit, which includes both battery and charger. Matching your platform saves money and avoids purchasing separate cells for a new brand.
-
Select appropriate voltage
Voltage determines the power potential of cordless grinders. The DEWALT 60V MAX 4-1/2 to 6-Inch Angle Grinder delivers high output comparable to 13 Amp corded units. Lower voltage options like the Makita 18V LXT 4-1/2-Inch X-Lock Brushless Grinder offer lighter weight for detailed work. Higher voltage suits heavy cutting, while lower voltage improves maneuverability for tight spaces and precision grinding tasks.
-
Consider motor type
Brushless motors provide higher efficiency and longer runtime than brushed alternatives. The DEWALT 20V MAX XR Variable Speed Angle Grinder uses a brushless design for up to 1,640 MWO output. This technology reduces maintenance and increases durability. If you grind frequently, brushless models like the Milwaukee M18 Brushless Paddle Switch Grinder offer better performance. Brushed motors are less common in these modern listings but may appear in older stock.
-
Evaluate weight and balance
Weight affects control during extended use. The DEWALT 20V MAX 4-1/2-Inch Brushless Paddle Grinder weighs only 3.75 pounds, reducing fatigue. Heavier corded models like the DEWALT 4-1/2-Inch 11-Amp Paddle Switch Angle Grinder weigh 8.25 pounds and provide stability for aggressive grinding. Lighter tools suit overhead work or intricate cutting. Compare the weight specifications to match your physical comfort and the demands of your typical projects.
-
Review switch style
Switch types change how you operate the tool. Paddle switches, found on the Milwaukee M18 Brushless Paddle Switch Grinder, require constant pressure, enhancing safety by stopping immediately when released. Trigger switches offer variable speed control and lock-on capability. Slide switches, like on the DEWALT 20V 4-1/2-Inch Slide-Switch Grinder, provide a different tactile feel. Choose the switch type that matches your hand preference and safety requirements for your specific tasks.
