Air Die Grind. Service Kit Rotor Blades (21) For At0017

At a Glance: Rotor blade (vane) service kit for the AirCraft AT0017 6mm Mini Air Die Grinder—refreshes the pneumatic motor for better power and smoother running.

The AirCraft AT0017-SK10 Service Kit supplies replacement rotor blades (also called vanes) for the AT0017 6mm Mini Air Die Grinder. These blades slide in and out of the rotor slots inside the motor, creating the sealing action that turns compressed air into torque and speed. When vanes wear down, the motor loses efficiency—often showing up as reduced power, slower speed under load, and a tool that feels “flat” compared to how it used to run. Replacing rotor blades is one of the most effective and affordable maintenance steps on a vane-type pneumatic motor. Fit fresh blades, lubricate correctly, and you’ll often feel an immediate improvement in response, smoothness, and overall performance.

Vanes are wear items by design. They seal against the cylinder wall as the rotor spins, so they gradually wear down. Fresh vanes restore that seal—improving airflow efficiency and bringing back the grinder’s punch.
