Compact reamer for accurate hinge-pin bores

The Arrowmax AM-490037-LE Arm Reamer 2.0 x 70mm Limited Edition is intended as a precision tool to clean, true, and size suspension arm holes and link bores. Its 2.0mm cutter diameter and 70mm reach are suitable for the common hinge-pin and link dimensions found on many 1/10-scale electric touring and off-road models.

Use the reamer during setup to produce concentric holes and remove machining or drilling burrs, resulting in smoother pivot action and consistent clearances. It helps achieve repeatable bore diameters prior to final assembly of arms and linkages.

Usage guidance: employ a pin vise or low-speed hand holder, align the tool carefully with the existing hole axis, and advance in light, controlled passes to the finish size. Avoid excessive force to prevent over-enlargement of the bore.

Technical details

  • Item: Arrowmax AM-490037-LE Arm Reamer 2.0 x 70mm Limited Edition
  • Model Number: AM-490037-LE

A specialist hand tool for standardising hinge-pin bore size and improving suspension repeatability; always test-fit the hinge-pin and check movement before completing assembly.

Will this reamer work with small touring car arms?

Yes, the 2.0mm diameter matches many small touring car hinge-pins; its 70mm length offers sufficient reach for most thin-profile arms used in 1/10 scale models.

How do I prevent oversizing the hole?

Use short, measured passes and check fit frequently with the actual hinge-pin. Stopping early and rechecking prevents accidental overcutting and preserves intended tolerances.

Is the tool suitable for repeated workshop use?

The listing does not detail material or hardness ratings; as a precision hand tool, its lifespan will depend on usage patterns and the materials worked. Treat it as a setup implement rather than heavy production tooling.

What should I inspect after reaming?

After reaming, check the bore with the hinge-pin for free movement, inspect edges for burs, and confirm there is no unwanted lateral play that could affect suspension tracking.
