Safety Features
Cordless convenience with strong power and safety features ensures confidence during operation.

The DEWALT 20V MAX Cordless 4 1/2 Inch Grinder is a compact and lightweight tool weighing about 4.8 pounds, which makes it easier to handle and less tiring for extended use. It runs on a 20-volt battery, offering the convenience of cordless operation, though you will need to provide your own battery and charger. This grinder spins at up to 9,000 RPM, giving it plenty of speed for cutting and grinding through tough materials like metal rebar. The 4 1/2 inch disc size is a common and versatile size, suitable for a range of tasks from cutting to grinding in tight spaces.

Safety is well covered with features like a kickback brake and an electronic clutch that help prevent sudden tool movement if the disc binds, making it safer to use. The brushless motor means it’s efficient and durable, providing strong power output up to 850 max watts. A downside is that since it’s battery-powered, runtime depends on your battery capacity, and it might not be ideal for very long or heavy-duty jobs without extra batteries. Also, this is the bare tool only, so additional components like batteries and charger must be purchased separately.

This grinder suits DIY enthusiasts and professionals looking for a portable, manageable grinder with solid power and safety features for light to medium duty work.

DEWALT 20V MAX XR Cut Off Tool, Brushless and Compact, Bare Tool Only (DCS438B)

The DEWALT 20V MAX XR Cut Off Tool (model DCS438B) is a compact, battery-powered tool designed primarily for cutting a variety of materials with precision. It features a brushless motor delivering 550 watts of power and spins up to 20,000 RPM, which means it can handle tough cutting jobs efficiently. The included blades, such as the bonded abrasive and diamond wheels, make it versatile for cutting metal, tile, and multi-material surfaces. The tool's disc size is 3 inches, smaller than many traditional angle grinders, which helps with maneuverability in tight spaces but may limit cutting depth on larger jobs.

Weighing just 3 pounds, it's lightweight and easy to control, reducing user fatigue during extended use. Safety and convenience are addressed with a removable dust shroud that can be connected to an extractor (sold separately) to reduce dust exposure, and a tool-free adjustable depth setting to control cutting precision. A bright LED light helps illuminate dark work areas, improving accuracy. Since this is a bare tool (battery not included), you’ll need a compatible 20V DEWALT battery, which is an additional cost if you don’t already have one.

Because it’s a cut off tool rather than a full-sized angle grinder, it may not be the best choice for heavy grinding or larger disc applications. It is well-suited for DIYers and professionals who need a portable, efficient cutting tool for detailed work and moderate cutting tasks.

Power (Amps)
Delivers exceptional power that effortlessly cuts through metal and concrete, making heavy-duty jobs feel easy.
Weight
Balances impressive strength with a comfortable, lightweight design that reduces user fatigue during extended use.
Safety Features
The built-in anti-kickback brake effectively prevents wheel damage and enhances safety during challenging cuts.

The DEWALT FLEXVOLT 60V MAX Angle Grinder is a powerful cordless tool with a motor equivalent to 13 amps, delivering strong performance suitable for both cutting and grinding tasks. It supports wheel sizes up to 6 inches, which is larger than the typical 4.5-inch discs, giving you more versatility depending on your project. The grinder spins at a fast 9,000 RPM, helping you finish jobs efficiently. Weighing 4.7 pounds, it is reasonably light for a heavy-duty tool, making it easier to handle during longer use.

One of its standout features is the advanced safety system: it includes a kickback brake and an electronic clutch that quickly stop the wheel if it senses a sudden pinch or stall, reducing the risk of injury or tool damage. This makes it safer to use, especially for less experienced users or challenging jobs. The tool is battery-powered (battery not included), so you get the freedom of cordless operation, though you’ll need to buy compatible batteries separately. The grinder comes with a 3-year limited warranty, reflecting DEWALT's confidence in its durability.

The high voltage battery system might be heavier and more expensive than standard 18V options, and since it’s tool-only, initial cost could be higher if you don’t already own FLEXVOLT batteries. This grinder is suited for users who want a powerful, cordless angle grinder with strong safety features and flexibility in disc size, making it ideal for construction, metalwork, or serious DIY projects.

Buying Guide for the Best Dewalt Angle Grinders

When choosing a DeWalt angle grinder, it's important to consider several key specifications to ensure you select the right tool for your needs. Angle grinders are versatile tools used for grinding, cutting, and polishing, and the right model can make a significant difference in your work efficiency and quality. Here are the key specs to consider and how to navigate them to find the best fit for you.
Power (Amps)The power of an angle grinder is measured in amps. This spec is important because it determines how much power the tool can deliver, which affects its performance and ability to handle tough jobs. Angle grinders typically range from 6 to 15 amps. Lower amp models (6-8 amps) are suitable for light-duty tasks like sharpening tools or minor cutting. Mid-range models (9-12 amps) are good for general-purpose use, including cutting and grinding metal or masonry. High amp models (13-15 amps) are designed for heavy-duty tasks and continuous use. Choose a power level based on the intensity and frequency of your work.
Disc SizeThe disc size of an angle grinder refers to the diameter of the grinding or cutting wheel. This spec is important because it affects the depth of cut and the surface area you can cover. Common disc sizes are 4.5 inches, 5 inches, 6 inches, and 7 inches. Smaller discs (4.5-5 inches) are ideal for precision work and tight spaces. Medium discs (6 inches) offer a balance between precision and coverage, making them versatile for various tasks. Larger discs (7 inches) are best for heavy-duty cutting and grinding, providing deeper cuts and covering more area quickly. Select a disc size based on the type of work you plan to do and the space you have to maneuver.
Speed (RPM)The speed of an angle grinder is measured in revolutions per minute (RPM). This spec is important because it affects how quickly the disc spins, which influences the cutting and grinding efficiency. Angle grinders typically have speeds ranging from 5,000 to 12,000 RPM. Lower speeds (5,000-7,000 RPM) are suitable for polishing and delicate grinding tasks. Mid-range speeds (8,000-10,000 RPM) are good for general-purpose cutting and grinding. Higher speeds (11,000-12,000 RPM) are ideal for fast, aggressive cutting and grinding. Choose a speed based on the material you will be working with and the precision required.
WeightThe weight of an angle grinder is an important consideration because it affects how comfortable and easy the tool is to handle, especially during extended use. Angle grinders can weigh anywhere from 4 to 12 pounds. Lighter models (4-6 pounds) are easier to maneuver and less tiring to use, making them suitable for overhead work or prolonged tasks. Medium-weight models (7-9 pounds) offer a balance between power and manageability, making them versatile for various applications. Heavier models (10-12 pounds) provide more stability and power for heavy-duty tasks but can be more tiring to use. Choose a weight that you can comfortably handle for the duration of your work.
Safety FeaturesSafety features in an angle grinder are crucial to prevent accidents and injuries. Important safety features include a paddle switch, which automatically turns off the grinder when released, a tool-free guard adjustment for quick and easy guard changes, and an anti-vibration handle to reduce user fatigue and improve control. Some models also have an electronic brake that stops the disc quickly when the trigger is released. Consider the safety features that are most important to you based on the type of work you will be doing and your experience level with power tools.
