What a Cut Off Tool Is

A cut off tool is a handheld power tool that uses a high-RPM motor to spin a thin cutting wheel, allowing the operator to slice through metal, plastic, fiberglass, tile, and other materials using abrasive friction. Unlike grinders, which remove material gradually, a cut off tool is designed specifically to make clean, controlled cuts with minimal material removal.

Core characteristics of a cut off tool include:

• High RPM output (often 10,000–25,000 RPM)

• Lightweight and compact design

• Single-handed or two-handed operation

• Thin cutting wheel to minimize heat and drag

• Precision performance in tight spaces

• Ability to cut various materials with different wheels

Because of its versatility and precision, this tool is widely relied upon by professionals across many trades.

How a Cut Off Tool Works

The strength of a cut off tool lies in its cutting wheel's high rotational speed. When the abrasive wheel spins at extremely high RPMs, each abrasive grain bites into the material, creating a clean cutting action.

Cutting process:

• High-speed rotation produces friction for efficient cutting.

• Thin kerf wheels minimize resistance and create smooth cuts.

• Abrasive edges grind through metal and other materials.

• Efficient airflow cools the wheel during operation.

• User-guided movement provides accuracy and control.

The combination of high-speed friction and abrasive grit allows the tool to cut materials far harder than what traditional saw blades can handle.
