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

Replacement tungsten tip for 1/8 arm holes

The Arrowmax AM-492024 is a tungsten steel cutting tip made to ream 1/8 scale arm holes to a nominal 3.17mm size. Supplied as the tip-only spare, it fits the matching reamer handle and is intended for RC suspension arms and related small chassis parts where accurate hole geometry is required.

Installing a fresh cutting tip restores the original tool performance without the expense of a whole reamer. Tungsten delivers good wear resistance for repeated reaming, helping retain clean hole edges and uniform diameters compared with worn cutters.

For workshop use, carry out measured, slow passes until the correct fit is achieved; consistent hole shape helps hinge performance and alignment. This item is designed for scale model use and not for full-size vehicles.
