Choosing between a cordless vs corded angle grinder depends on your power needs and workspace. Both the DEWALT DCG410B and Makita 9564CV are bare tools designed for professional use. They share a 4-1/2-inch wheel diameter for compatibility with standard discs. The main difference lies in their power source and motor technology. One relies on a 20V battery system for mobility, while the other uses a 13-amp corded motor for continuous output. You must decide which setup fits your workflow.

Cordless vs Corded Angle Grinder Specs

Motor Type and Power

Edge: Tie

The DEWALT DCG410B features a brushless motor, which typically offers better efficiency and longer runtime on battery power. It delivers up to 1,590 MWO. The Makita 9564CV uses a powerful 13-amp corded motor. This direct electrical connection allows for consistent high output without the degradation of battery charge. Brushless technology in the DEWALT reduces internal friction and heat. The Makita’s corded design ensures you never worry about power depletion during heavy tasks. Both are built for professional use, but the power delivery method differs significantly between battery efficiency and direct current strength.

Speed and Control

Edge: Makita 9564CV 4-1/2-Inch Corded Grinder

The Makita 9564CV offers a variable speed range from 2,800 to 10,500 RPM. This allows you to match the speed precisely to the material you are grinding or cutting. The DEWALT DCG410B runs at a fixed maximum speed of 9,000 RPM. While fast, it lacks the dial adjustment found on the Makita. The Makita also includes constant speed control, which maintains RPM under load. This is crucial for keeping cuts clean when pressure increases. The DEWALT relies on its brushless motor to handle load, but you cannot manually adjust the speed. For tasks requiring specific RPMs, the Makita provides more flexibility.

Weight and Portability

Edge: DEWALT 20V MAX XR 5-Inch Brushless Angle Grinder

The DEWALT DCG410B weighs 4.59 pounds, making it lighter than the Makita 9564CV, which weighs 6 pounds. This weight difference matters when you are working overhead or in tight spaces. The DEWALT is also more compact, measuring 13.1 inches in length compared to the Makita’s 16 inches. The Makita’s extra weight comes from its heavy-duty corded components and larger motor housing. For extended periods of use, the lighter DEWALT may reduce arm fatigue. However, the Makita’s weight can provide stability during aggressive grinding. Portability favors the cordless option significantly.

Safety and Protection

Edge: Tie

The Makita 9564CV includes Sass technology, a mechanical clutch that allows the drive shaft to slip if the wheel binds. This prevents motor and gear damage from sudden stops. The DEWALT DCG410B uses an anti-rotation system that senses excessive rotational motion and shuts down the tool. Both systems protect the user and the machine, but they operate differently. The Makita’s clutch is a mechanical safeguard against jamming. The DEWALT’s sensor stops the tool entirely if motion becomes unsafe. The Makita also features a soft start to suppress reaction torque. Both tools prioritize operator safety through distinct engineering approaches.

Wheel Diameter Compatibility

Edge: Tie

Both the DEWALT DCG410B and the Makita 9564CV accept 4-1/2-inch wheels. This is the most common size for angle grinders, ensuring you have access to a wide variety of discs and cutting wheels. The DEWALT model is listed as compatible with 4-1/2 to 5-inch wheels in some descriptions, but the key specs highlight 4-1/2-5 inch. The Makita is strictly a 4-1/2-inch model. For standard 4-1/2-inch discs, both tools are fully compatible. You can use the same abrasive wheels on either machine without adapters. This shared compatibility simplifies your inventory of consumables.

Choose Your Angle Grinder By Need

You need variable speed for stone

Our pick: Makita 9564CV 4-1/2-Inch Corded Grinder

The Makita 9564CV offers variable speed control from 2,800 to 10,500 RPM. This range lets you match the speed to specific applications like stone grinding. The constant speed control maintains RPM under load. This precision helps prevent damage and ensures cleaner cuts on delicate materials compared to fixed-speed alternatives.

You want lighter portable tool

Our pick: DEWALT 20V MAX XR 5-Inch Brushless Angle Grinder

The DEWALT DCG410B weighs 4.59 pounds, which is lighter than the Makita's 6 pounds. Its brushless motor maximizes runtime on a single battery charge. You can work without a cord restriction. The compact design reduces fatigue during overhead tasks. This makes it ideal for job sites where mobility matters most.

You prefer continuous heavy duty

Our pick: Makita 9564CV 4-1/2-Inch Corded Grinder

The Makita 9564CV provides a 13-amp corded motor for uninterrupted power. You do not need to wait for battery recharges. The SJS technology acts as a mechanical clutch to protect gears if the wheel binds. This system helps prevent motor damage during tough, continuous grinding tasks that drain batteries quickly.
