Hitachi Side Handle - 313-078

Hitachi 313078 — original Hitachi side handle replacement for rotary and demolition hammers. This is the genuine side‑handle assembly (includes the collar / holder and fastening hardware used on the tool) designed to clamp onto the tool’s front handle holder and restore a secure two‑hand grip for heavy drilling or chiseling.

Compatible with many Hitachi / HiKOKI rotary‑hammer models, including DH30PB, DH30PC, DH30PC2 /DH40FA, DH40FB, DH40FR, DH40MA, DH40MB, DH40MR, DH40MRY, DH40RMY, DH40SA, DH40YB, DH45MR — a direct replacement listed in the parts diagrams for these tools.

Easy to fit: the part is sold as the single replacement handle assembly and typically mounts to the tool’s handle holder without special tooling — simply secure it with the existing clamp/bolt arrangement and you’re back to steady, controlled operation. If you’re replacing worn or broken power tool parts and need the exact factory handle, this 313078 restores the original fit and feel.
