S drill is a modular high-performance replaceable insert drill innovatively launched by CHTOOLS.

The triple positioning structure for which a patent is licensed features extraordinary connection strength and positioning accuracy, and the optimal geometric design and materials contribute to its excellent drilling speed and durability.

Given the split replaceable construction, it can achieve a flexible combination of inserts of various functions and holders of different lengths, thereby satisfying the needs of different materials to be processed, different drilling depths and other applications, and achieving the advantages of minimized tool investment and less inventory.
