The HUDY 107632 Arm Reamer helps hobbyists and club racers get correct fitment on 1/8 scale suspension arms. Removing rough edges and tight spots keeps arms moving freely for steadier handling.
The reamer's 3.5mm cutting tip is intended to reshape plastic arm holes accurately. A hand-ground face produces tiny scurfies that limit tearing and prevent the hole from ending up oversized, yielding a secure pivot fit.
To use, feed the tip into the arm hole and push while rotating the tool by hand. Continue until the shaft meets the handle, then reverse to extract the tool. This simple method eliminates binding and restores smooth suspension travel.
