Cleveland C46890 Port Tool 2.375" L .250" dia pneumatic accessory

Cleveland C46890 Port Tool

The Cleveland C46890 is a pneumatic accessory designed for precision porting tasks. It features a 2.375" length and a .250" diameter constructed from high-speed steel. The tool uses an interchangeable pilot system for accurate alignment during operation. This new accessory suits professional mechanics and industrial maintenance teams.

Suits technicians needing a counterbore with pilot

This tool fits operators who require a dedicated aircraft-length counterbore for specific port dimensions. It is not suited for buyers who need a larger cutting diameter or a longer reach than the 2.375" specification provides. Users without a compatible pneumatic power source should look at alternative hand-operated tooling. The interchangeable pilot design requires separate pilot selection for each job.

Simple collet installation with pilot care

Installation involves securing the .250" shank into a standard pneumatic tool holder or collet chuck. The interchangeable pilot must be matched to the hole size before use to prevent misalignment. A common issue is pilot wear leading to off-centre cuts if not inspected regularly. Ensure the tool runs at the correct speed for high-speed steel to avoid premature dulling.
