2.5mm Arm Reamer 70mm Shaft - Arrowmax AM-490039-LE  [AM-490039-LE]

Hand reamer for RC pivot holes

The Arrowmax AM-490039-LE Arm Reamer 2.5 X 70mm Limited Edition is intended for hobbyists who need to prepare and tidy pivot holes in suspension arms and small linkage parts.

This reamer opens, deburrs, or slightly enlarges 2.5mm arm pivot holes so that plastic or composite arms will accept metal inserts, bearings, or hinge pins with a cleaner, more accurate fit. The 70mm shaft length provides extra reach into compact chassis layouts while helping keep the tool steady during manual reaming.

Use manually: secure the component, align the reamer with the hole, and rotate with steady pressure to remove material gradually. Do not force the tool; check the fit frequently to reach the desired clearance without over-reaming.

A practical tool for setup and tuning sessions where controlled pivot-hole sizing matters; handle with care and inspect work as you progress to avoid removing excess material.
