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

Precision hand reamer for suspension arms

The Arrowmax AM-490039-LE Arm Reamer 2.5 X 70mm Limited Edition is a handheld setup tool designed to prepare and refine arm pivot holes on model suspension arms and linkage parts.

Use the reamer to open, deburr, or slightly enlarge 2.5mm arm pivot holes so plastic or composite arms accept metal inserts, bearings, or hinge pins with a cleaner fit. The 70mm shaft reaches into compact chassis areas while helping keep the tool aligned during manual use.

Operation is manual: secure the arm or part in a bench vise or fixture, align the reamer with the existing hole, and rotate with steady, controlled pressure to remove material. Avoid forcing the tool and check fit frequently to achieve the required clearance.

A useful addition to a setup kit for hobbyists who need controlled reaming of RC arm pivot holes during alignment and tuning; handle carefully and inspect parts as you progress.
