Arrowmax AM-490022-BG 3.5 x 120mm Arm Reamer Black Golden Edition  [AM-490022-BG]

True-Bore Reamer for RC Arms

The Arrowmax AM-490022-BG arm reamer gives model builders a reliable way to open and true arm holes. Its 3.5 x 120mm profile helps create consistent bores that improve part seating and suspension repeatability.

Durable Black Golden Surface

The Black Golden finish adds a professional appearance and aids in resisting surface wear. That coating also simplifies cleaning and helps the tool last through frequent workshop use.

Precision Work for Consistent Handling

Use the reamer to dial in arm hole sizes so suspension components sit without slack. Accurate fitment reduces variable movement and supports stable handling across different tracks.
