[Cautionon Secondary Opérations] © Please read "Caution on Performing Secondary Opérations" (Page 416) when performing modifications and/or secondary opérations for safety concerns. Haguruma Kobo, the KHK's system for quick modification of KHK stock gears is also available. © Due to the gear teeth being induction hardened, no secondary operations can be performed on tooth areas including the bottom land (approx. 1 mm). Use carbide tools for the modification of the shaft area near the bottom land.
