Key Features of the Milwaukee M18 Cut-Off Tool

1. Cordless Convenience

The M18 Cut-Off Tool runs on Milwaukee’s M18 REDLITHIUM™ batteries, which deliver extended runtime and consistent power. Cordless operation means no cords to manage, fewer trip hazards, and the ability to work in tight or remote spaces where electricity isn’t readily available.

2. High-Speed Motor

Equipped with a powerful brushless motor, the M18 Cut-Off Tool can spin cutting wheels at up to 7,500 RPM, enabling fast and efficient cutting through thick metal or rebar. Brushless motors are also more durable and energy-efficient, increasing the tool’s overall lifespan.

3. Compact and Ergonomic Design

The tool’s slim profile and balanced weight make it comfortable to hold for extended periods. The ergonomic grip reduces hand fatigue, allowing users to work longer without strain. The compact size also helps reach tight spots where larger saws can’t fit.

4. Quick Access Wheel Release

Changing cutting wheels is quick and easy thanks to the tool’s simple, tool-free wheel release mechanism. This minimizes downtime and keeps you productive on the job.

5. Adjustable Depth Guard

Safety is a priority with the M18 Cut-Off Tool. The adjustable depth guard helps protect the user from debris and sparks during cutting, while also controlling the depth of the cut for precision.

6. Variable Speed Control

Some models include variable speed control, allowing users to adjust cutting speed to match the material, improving control and finish quality.

7. Compatibility with Multiple Wheel Types

The M18 Cut-Off Tool supports a range of wheel types, including metal cutting wheels, abrasive discs, and diamond blades, expanding its versatility across different materials and projects.
