DEWALT Angle Grinder Lineup
DEWALT offers grinders in bare tool and kit formats. You can choose between cordless 20V MAX and 60V MAX options, or corded models with 11 to 13-amp motors. The lineup includes single tools and two-tool sets like the DCK203P1. Most models feature 4-1/2-inch wheels, though larger 5, 6, and 7-inch options exist for heavy cutting. Motor types vary from brushed to brushless designs, affecting maintenance needs. Some kits include batteries and chargers, while others require you to supply your own power source. Switch styles range from paddle to slide and trigger types. You should select based on your existing battery platform and required wheel diameter. The DEWALT 20V MAX 4-1/2-Inch Brushless Paddle Grinder leads the cordless segment. For corded work, the DWE402K provides continuous power. The DCG414B handles large 6-inch wheels. The DCG440B accommodates 7-inch discs.
Where DEWALT Fits
DEWALT covers a wide range of grinding needs. You can pick from compact 4-1/2-inch grinders to heavy 7-inch cutters. The lineup includes slim cordless models for tight spaces and robust corded units for shop work. Most tools use paddle or trigger switches. You will find brushless motors in many cordless options. However, none of the listed products offer variable speed control in the corded models. Also, no 3-inch or 9-inch grinders appear here. If you need those specific sizes, this brand’s current selection does not cover them.
If you require kitchen appliances rather than workshop equipment, review specifications for the best 1100W food grinders.
How to choose the right angle grinder
-
Pick your power source
Decide between corded and cordless operation first. Corded models like the DWE402K deliver continuous 11-amp power for heavy grinding without battery anxiety. Cordless options offer mobility but require battery management. If you already own DEWALT 20V batteries, a bare tool like the DCG413B makes sense. For maximum cordless power, the DCG414B uses 60V MAX batteries for higher output. Choose corded for shop work and cordless for job site flexibility.
-
Check wheel diameter needs
Wheel size determines cutting depth and material removal. Most models use 4-1/2-inch wheels for general metalwork. Larger wheels handle thicker stock. The DCG410B accepts 5-inch wheels for increased cutting capacity. The DCG440B takes 7-inch wheels for heavy-duty pipeline work. The DCG414B accommodates 6-inch wheels. Match the wheel size to your heaviest expected cut. Smaller wheels are lighter and easier to control. Larger wheels require more power and offer deeper cuts.
-
Select the motor type
Brushless motors provide longer life and better efficiency than brushed versions. The DCG413B uses a brushless motor for low maintenance. The DCG410B also features brushless technology. Brushed motors in corded models like the DWE43116 are robust but require brush replacement. Brushless units often deliver higher RPMs or torque. Check the attributes for motor type. If you grind frequently, brushless saves time on upkeep. Brushed motors are simpler and often less expensive in bare tool form.
-
Review included tools
Bare tools require separate battery and charger purchases. The DCG413B is sold as a bare tool. Kits like the DCG407P1 include batteries and chargers. The DCK203P1 includes two tools and a 5Ah pack. If you lack DEWALT batteries, buy a kit. If you have a full battery lineup, bare tools save money. Check the Battery Included attribute carefully. Some kits include one battery, others include two. Factor the cost of additional batteries into your total setup expense.
-
Consider switch style
Switch type affects control and fatigue. Paddle switches offer quick release and safety. The DCG413B uses a paddle switch. Slide switches allow lock-on for continuous grinding. The DCG405B features a slide switch. Trigger switches provide variable control. The DWE43116 uses a trigger. Paddle switches are safer for one-handed operation. Slide switches reduce hand fatigue during long cuts. Choose based on your grip preference and safety requirements. Some models offer variable speed for material-specific control.
-
Evaluate weight and size
Weight impacts comfort during extended use. The DCG413B weighs 3.75 pounds for reduced fatigue. The DWE402K weighs 8.25 pounds due to its corded design. The DCG414B weighs 6.61 pounds. Lighter tools are easier to maneuver in tight spaces. Heavier tools may offer more stability. Check the specs for weight and dimensions. The DCG402B is slim for tight areas. Balance power requirements with physical comfort. A lighter tool reduces arm strain during overhead or prolonged grinding tasks.
