Precision Bore Work with the Arrowmax AM-490021-BG

The Arrowmax AM-490021-BG Precision Arm Reamer is designed to bring consistent bore sizing to suspension arms. The 3.0mm cutting diameter and extended 120mm length suit workshop duties where control and reach are required, and the black golden finish contributes to tool longevity.

Performance You Can Measure

Use this reamer to fine tune arm holes and improve hinge pin seating for better steering response and reduced slop. The 3.0mm dimension provides a repeatable reference size for alignment, while the finish helps the reamer resist surface wear during regular use.

Specifications

  • Diameter: 3.0mm
  • Length: 120mm
  • Finish: Black Golden
  • Application: Suspension Arm Tuning

For tuners focused on reliable, repeatable arm bore sizing, the Arrowmax AM-490021-BG is a practical addition to workshop kit.

Is this reamer safe for aluminium arms?

Yes, it can be used on aluminium arms but use steady, controlled passes and ensure chips are cleared to avoid binding. A light cutting lubricant can help for metal work.

What is the best way to check the bore after reaming?

Check fit with the actual hinge pin or a 3.0mm gauge pin, and test movement in the chassis. Inspect for tight spots and rework lightly if needed.

Does the finish affect precision?

The black golden finish mainly protects against wear and corrosion; it does not alter the cutting profile but helps the tool keep a stable surface for repeated use.
