W&H S-8S Sagittal Saw Handpiece

The S-8S is a sagittal surgical saw handpiece designed for efficient bone cutting where a longer cutting arc and higher material removal rate are required. The sagittal motion produces a broader, sweeping cutting action, making the S-8S well suited for larger osteotomies and procedures requiring extended linear cuts.

With a compact design and high stroke frequency, the S-8S delivers powerful, predictable cutting while maintaining control. The handpiece is fully dismantlable to support stringent surgical hygiene protocols and long-term clinical use.
