Star KNC32 Swiss Type Live Turret Tool Holder

Star KNC32 Swiss Type Live Turret Tool Holder is a 90° live-tooling cartridge for Swiss-type lathes, featuring a 44 mm shank and a 5/8 in arbor. The KNC32 designation identifies this holder as part of Star’s Swiss-type tool-holding family, designed to house live cutting tools within a turret arrangement and to maintain stable tool alignment during rotation. With its 90° geometry, the holder positions the tool perpendicular to the spindle axis, enabling access to features on the workpiece without excessive reach inside the turret cavity. The 44 mm shank provides a substantial seating surface in the tool socket, contributing to rigidity and repeatability when tools are clamped for cycling at high speeds. The 5/8" arbor diameter defines the interface for mounting and driving the tool within compatible Star Swiss machines and tool posts, ensuring consistent torque transfer and concentricity. This combination of angle, shank size, and arbor makes the KNC32 a compact, robust option for live-tooling tasks in precision turning environments, where small-diameter parts benefit from integrated tooling that can perform drilling, grooving, or boring operations in a single cycle. When selecting a holder, ensure the KNC32 model corresponds to the turret and post geometry of your Star Swiss-type system to maximize rigidity and repeatability across tool changes.
