Spline‑to‑SDS‑Max Bit Adapter

Convert Spline Hammers to SDS‑Max • Universal Heavy‑Duty Adapter

The Spline‑to‑SDS‑Max adapter allows you to run modern SDS‑Max bits on older Spline‑drive rotary hammers. This adapter is perfect for contractors who still use legacy Spline tools but want access to the full range of SDS‑Max bits — including your 1/2″, 1″, 1‑7/16″, and 1‑9/16″ Hawaiʻi contractor series.

Built from hardened tool steel with precision‑machined tolerances, this adapter maintains drilling power, reduces vibration, and ensures a secure fit between the Spline chuck and SDS‑Max bit shank.

Ideal for commercial contractors, demolition crews, and industrial maintenance teams across Oʻahu, Maui, and the outer islands.
