1/8 (3.17mm) Tungsten Arm Reamer Tip - Arrowmax AM-492024  [AM-492024]

Precision 1/8 arm reamer tip

The Arrowmax AM-492024 replacement tip is a tungsten steel cutting tip designed specifically for 1/8 scale arm reaming, sized for 3.17mm (1/8) holes and intended as a tip-only spare for the matching reamer handle. It is built for use on RC model suspension arms and other small chassis parts where accurate hole sizing is required.

As a tip-only spare, this part lets you restore cutting performance without replacing the entire tool. Tungsten steel provides wear resistance for repetitive reaming tasks, helping maintain consistent hole diameter and cleaner edges compared with blunt or improvised cutters.

In workshop use, the tip is suited for controlled, slow reaming passes to bring arm hinge-pin or bushing holes to the correct fit. It supports fine adjustment work during setup and tuning, where consistent hole geometry affects hinge movement and alignment. This is an RC-scale accessory and not for real vehicle use.
