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

Precision tip for arm hole reaming

This Arrowmax AM-492039 arm reamer tip is an RC-scale cutting insert supplied as the tip only, created for trimming, cleaning, and sizing suspension arm and linkage bores. The tungsten steel cutting edge is hardened for repeatable deburring of small alloy and plastic holes so pins and fasteners seat consistently during assembly.

As a tip-only item it must be fitted into a suitable holder or chuck for controlled reaming. Use light, steady passes and keep the reamer coaxial with the hole to avoid creating an oval bore. The tool is helpful when building a new model, swapping components, or checking hole alignment as part of setup work.

Care is simple: remove swarf after each use, check the edge for chips or wear, and keep the tip dry to limit corrosion. Handle the tungsten tip gently to minimise the risk of chipping the cutting edge.
