Arrowmax Tungsten Tip AM-492037 for 2.0mm Arm Reamer  [AM-492037]

Replacement Cutting Tip for Arm Holes

The Arrowmax AM-492037 replacement tip is a tungsten steel cutting insert designed to ream and restore 2.0mm arm holes on RC components. Sold as the tip only, it is used by hobbyists who swap worn inserts to maintain correct arm-to-pin fit.

Use notes: mount the tip into a compatible reamer holder or shaft and perform controlled passes to reach a true 2.0mm diameter. It is intended for fine trimming, deburring, and correcting slightly enlarged or irregular holes so pins and pivot bearings seat properly.

Tuning role: restoring uniform arm hole size stabilises suspension geometry and improves repeatability when tuning steering and chassis balance, making setup sessions more reliable.
