2.5 X 70MM Arm Reamer Tip (Tungsten Steel) - Arrowmax AM-492039  [AM-492039]

Tooling for precise setup and tuning

The Arrowmax AM-492039 is a tungsten cutting tip offered as the replacement insert only, crafted to clean and size suspension arm and linkage bores for precise fitment. Using a hard tungsten edge helps remove burrs and lightly enlarge holes so pins and fasteners seat uniformly, which can be critical when fine-tuning suspension geometry and assembly tolerances.

Install the tip into a compatible holder or chuck before use and perform steady, controlled passes while keeping the cutter coaxial with the bore to preserve roundness. This approach is valuable during initial assembly, part replacement, and when validating alignment as part of setup tuning procedures.

Maintain the tip by clearing swarf after each session, checking the edge for wear or chips, and storing it dry. Handle the tungsten component carefully to avoid chipping the cutting surface and degrading precision.
