Hitachi 311-013 Spare Part - Wrench

Original Hitachi blade wrench — part number Hitachi 372446 (Was Hitachi 311013) — a factory replacement wrench used to loosen and tighten the arbor/blade nut on Hitachi/HiKOKI (Metabo HPT) mitre saws.

This is the small, sturdy blade wrench that ships as the factory accessory for 10" (255 mm) slide compound mitre saws such as the HiKOKI/Hitachi C3610DRA (blade diameter 255 mm) and compatible Metabo HPT/Hikoki models — example listings also show fit for C8Fshg-style mitre saws.

Simple direct-fit replacement: part 372446 matches the factory parts diagram and drops in where the original wrench belongs, so you can change or reinstall blades and arbor nuts without modifying the tool. The part is sold as the blade wrench accessory and is described by parts suppliers as a durable, purpose-made tool for blade changes.
