Hudy Arm Reamer Replacement Tip # 4.0X120mm

The Hudy Arm Reamer Replacement Tip 4.0x120mm (part DY107624) is a precision spare tip designed for R/C use. With a 4.0mm diameter and 120mm length, this hand‑ground tip is engineered to accurately resize plastic suspension arm holes, helping you achieve a smooth, free‑moving suspension without introducing excessive slop.

The cutting surface features sharp micro scurfies to size plastic cleanly and consistently, reducing the risk of tearing, stressing or over‑sizing the hole. Ideal for fine suspension setup work where binding can negatively affect handling.
