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

Suspension arm reaming tool

The Arrowmax AM-490039-LE Arm Reamer 2.5 X 70mm Limited Edition is an RC setup tool for preparing and improving pivot holes in suspension arms and linkage elements.

Employ this reamer to open, deburr, or slightly enlarge 2.5mm arm pivot holes so that plastic or composite arms will accept metal inserts, bearings, or hinge pins with a neater fit. The 70mm length allows access into confined chassis areas while helping stabilise the shaft during manual operation.

Manual use is advised: secure the part, line up the reamer with the existing hole, and rotate with steady pressure, removing material in small passes. Avoid heavy forcing and inspect the fit often to achieve the correct clearance.

Ideal for model builders who require fine control over pivot-hole sizing during setup and tuning; always proceed carefully to protect parts and obtain consistent results.
