The HUDY 107623 Arm Reamer Replacement Tip is crafted for 1/10 scale RC cars and offers a 3.0mm diameter with a 120mm length for controlled plastic reaming. It lets you reopen or fine-tune suspension arm holes so pivot points run freely.
Micro scurfies on the pin are hand-ground to slice plastic precisely instead of tearing, which helps preserve the arm geometry. That careful finish reduces binding and improves repeatable handling in tight sections and on rough layouts.
