Arrowmax AM-490037-LE Arm Reamer 2.0 x 70mm Limited Edition — Suspension arm reamer  [AM-490037-LE]

Precision reamer for suspension arms

The Arrowmax AM-490037-LE Arm Reamer 2.0 x 70mm Limited Edition is an RC-scale setup tool designed to clean and size arm holes and link bores. Its 2.0mm cutting diameter and 70mm length match common hinge-pin and linkage dimensions used on 1/10 and similar electric touring and off-road platforms.

Use this reamer during chassis setup to make hinge-pin holes concentric and sized for smooth articulation without excessive play. It removes burrs, squares up drilled holes, and helps achieve a consistent bore diameter before final assembly of suspension arms and linkages.

Operation notes: hold the reamer in a pin vise or by hand at low speed, keep steady alignment with the existing hole axis, and take light passes until the desired finish is reached. Do not force the tool; steady, controlled cuts reduce the chance of enlarging the bore beyond intended tolerance.

A focused setup tool for hobbyists aiming to standardize hinge-pin bore size and improve suspension consistency; combine with careful measurement and test assembly for best results.
