Arrowmax AM-490037-LE Arm Reamer 2.0 x 70mm Limited Edition — Arm reamer for RC suspension setup  [AM-490037-LE]

Arm reamer for RC suspension tuning

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

This reamer is used during chassis setup to ensure hinge-pin holes are concentric and sized to permit smooth movement without excessive play. Use it to remove burrs, square up drilled holes, and achieve repeatable bore diameter before final assembly of suspension arms and linkages.

Operation notes: mount the reamer by hand or in a low-speed pin vise, apply steady alignment to the existing hole, and take light passes until the desired bore finish is reached. Avoid forcing the tool; consistent, controlled cuts reduce risk of enlarging the hole beyond intended tolerance.

This tool serves a focused role in RC setup workflows, helping to standardize hinge-pin bore size and improve suspension consistency; pair it with careful measurement and trial assembly for best results.
