Arrowmax AM-490039-LE 2.5 X 70mm Arm Reamer for RC  [AM-490039-LE]

Arm reamer for model suspension

The Arrowmax AM-490039-LE Arm Reamer 2.5 X 70mm Limited Edition is a setup tool for refining pivot holes on suspension arms and linkage components in scale RC models.

Use this tool to carefully open, clean, or slightly enlarge 2.5mm arm pivot holes so plastic or composite arms accept metal inserts, bushings, or hinge pins with improved alignment. The 70mm length helps reach into narrow chassis areas while keeping the shaft steady by hand.

Manual operation is recommended: clamp the part securely, line up the reamer with the existing hole, and turn with steady, even pressure to remove material gradually. Stop regularly to check fit and avoid removing too much material.

An accessory suited to a modeller's setup kit when precise control of pivot hole size and finish is required; always work cautiously and inspect the component as you go.
