Arm Reamer 2.0 x 70mm for RC Suspension - Arrowmax AM-490037-LE  [AM-490037-LE]

Why this reamer matters for setup

The Arrowmax AM-490037-LE Arm Reamer 2.0 x 70mm Limited Edition is a precision setup implement for cleaning and sizing suspension arm holes and linkage bores. The 2.0mm cutting diameter and 70mm length align with standard hinge-pin and link dimensions used across many 1/10-scale electric touring and off-road platforms.

Applied during chassis build or during setup changes, the tool helps achieve concentric, correctly sized bores that allow predictable suspension movement. It is effective at removing burs, squaring up holes, and producing consistent bore diameters before final assembly.

Best practice: mount the cutter in a pin vise or low-speed hand tool, keep the reamer coaxial with the current hole, and take measured, light cuts until the finish is achieved. Forcing the reamer will risk oversizing the bore and compromising fit.

A targeted tool for tuners and builders seeking repeatable hinge-pin bore sizing; always verify bore fit with the intended pin or link before final assembly.
