DeWalt DCS438B 20V MAX XR Brushless Cut-Off Tool
Best OverallPros
- Brushless motor for longer runtime
- Lightweight and compact design
- Tool-free wheel change
Cons
- Battery and charger sold separately
- Small wheel limits depth of cut
The DCS438B is DeWalt's most popular cordless cut-off tool. It uses a brushless motor to deliver 20,000 RPM, making it effective for cutting rebar, bolts, and thin metal sheets. Owner reviews on Amazon and Home Depot consistently praise its runtime with a 5Ah battery, often completing a full day of light-duty work on a single charge.
The tool weighs only 2.4 pounds, reducing fatigue during overhead work. The tool-free wheel change system is simple and secure. The main limitation is the 3-inch wheel, which restricts cut depth to about 5/8 inch. For thicker materials, you will need multiple passes or a larger tool.
DeWalt DWE4202 4-1/2-Inch Small Angle Grinder with Cut-Off Guard
Best CordedPros
- Unlimited runtime
- Accepts standard 4-1/2 in. wheels
- Durable motor for heavy use
Cons
- Requires a power outlet
- Heavier than cordless models
The DWE4202 is a corded angle grinder that works well as a cut-off tool when fitted with the included cut-off guard. It uses a 4-1/2 inch wheel, which provides a deeper cut (up to 1-1/2 inches) compared to the DCS438B. The 11,000 RPM speed is standard for this class and delivers consistent power for cutting rebar, angle iron, and tile.
Owner reviews note that the tool runs smoothly and the spindle lock makes wheel changes easy. The main drawback is the cord, which can be a tripping hazard and limits mobility. However, for continuous cutting tasks like framing or demolition, the unlimited runtime is a major advantage over battery-powered tools.
DeWalt DCS389B 60V MAX FLEXVOLT 7-1/4-Inch Cut-Off Saw
Best for Heavy-Duty CuttingPros
- Deep cuts up to 2-1/2 in.
- Powerful brushless motor
- FLEXVOLT battery works with 20V tools
Cons
- Heavy and bulky
- High price point
The DCS389B is a large cut-off saw designed for cutting thick metal, masonry, and pipe. It uses a 7-1/4 inch blade and delivers 5,000 RPM. The 60V FLEXVOLT battery provides high power and runtime, comparable to a corded abrasive saw. Owner reviews highlight its ability to cut through schedule 40 steel pipe and rebar with ease.
The tool is heavy at 7.5 pounds, which can cause fatigue during extended use. The FLEXVOLT battery is also expensive and heavy. However, for professionals who need a portable solution for heavy cutting tasks, this tool offers performance that rivals corded models. It is not suitable for light-duty or overhead work.
DeWalt DCS439B 20V MAX XR Brushless Cut-Off Tool (Variable Speed)
Best for Precision CuttingPros
- Variable speed trigger for control
- LED work light
- Brushless motor
Cons
- More expensive than DCS438B
- Still limited by 3 in. wheel
The DCS439B is a variable-speed version of the DCS438B. The trigger allows you to adjust the speed from 8,000 to 20,000 RPM, which is useful for cutting softer materials like plastic or copper without melting them. It also includes an LED light for better visibility in dark spaces.
Owner reviews appreciate the added control for precision work, such as cutting bolts flush to a surface. The tool shares the same form factor as the DCS438B, so it is lightweight and compact. The main downside is the higher price for the variable speed feature, which may not be necessary for basic cutting tasks.
What to Check Before Buying a DeWalt Cut Off Tool
Choosing the right cut-off tool depends on your specific needs. Here are the key factors to consider.
Power Source: Cordless tools offer portability but require battery investment. Corded tools provide unlimited runtime but limit mobility. For occasional use, a corded tool is more cost-effective. For job site work, cordless is often preferred.
Wheel or Blade Size: Smaller wheels (3-inch) are good for bolts and thin metal. Larger wheels (4-1/2 inch and 7-1/4 inch) allow deeper cuts in thicker materials. Match the wheel size to the thickness of the material you cut most often.
Speed and Control: Fixed speed tools are simpler and often cheaper. Variable speed tools give you more control for cutting different materials. For precision work, variable speed is a valuable feature.
Weight and Ergonomics: Lighter tools reduce fatigue during overhead work. Heavier tools with larger wheels are better for ground-level heavy cutting. Consider the balance and grip of the tool before buying.
Mistakes to Avoid When Choosing a Cut Off Tool
Many buyers make these common mistakes. Avoid them to save time and money.
Buying a tool that is too small for the job: A 3-inch cut-off tool cannot cut through thick steel pipe. If you need to cut large materials, choose a tool with a 4-1/2 inch or 7-1/4 inch wheel.
Ignoring battery compatibility: If you already own DeWalt 20V tools, the DCS438B or DCS439B will share batteries. If you own 60V FLEXVOLT tools, the DCS389B is a better fit. Buying a tool with a different battery system adds cost.
Overlooking safety features: Cut-off tools are dangerous. Look for models with a guard, a lock-off switch, and a two-finger trigger. Always wear eye and ear protection.
Who Is a DeWalt Cut Off Tool For?
DeWalt cut-off tools are designed for professionals and serious DIYers. The cordless models are ideal for tradespeople who need a portable tool for cutting bolts, rebar, conduit, and thin metal sheets on job sites. The corded models are better for workshop use or continuous cutting tasks where runtime is critical.
DIYers who occasionally cut metal or tile will find the corded DWE4202 to be a cost-effective option. It uses standard 4-1/2 inch wheels, which are widely available and inexpensive. The cordless models are a better fit for those who already own DeWalt 20V or 60V batteries.

Alternatives to DeWalt Cut Off Tools
If you are considering other brands, here are some alternatives.
