Seiki KV45Z-SLB28 Live Straight Toolholder For CNC Lathe

The Seiki KV45Z-SLB28 Live Straight Toolholder is a straight live-tooling holder for the Hitachi Seiki KV45 CNC lathe family. It accepts a 1-1/16" tool shank and is keyed for a positive drive, ensuring consistent rotation of the cutting edge during live-tooling operations. As part of the KV45 tooling lineup, this holder installs in the KV45 turret position to enable milling and drilling tasks on a turning center without removing the workpiece, expanding the machine’s capability for combined turning and milling. The SLB28 designation identifies the straight-toolholder configuration within the KV45Z family, providing a compact, rigid interface that supports precise tool alignment and repeatable performance in demanding turning applications. Note that a KV45X-SLB28 variant exists for a 90° live-tooling configuration, illustrating how the KV45 platform supports both straight and angled live-tooling options while maintaining the same 1-1/16" tool-shank compatibility.
