HomeProductsLathe Auxiliary Tool Holder for Straight-Shank Boring Bars, Drills & U-Drills

This series of auxiliary tool holders delivers multi-scene versatility and fits a wide range of straight‑shank tools, including internal boring bars, twist drills, U‑drills and extension rods. Mainly engineered for clamping boring bars on lathes, they are regularly mounted on tool posts or turrets to maintain stable tool performance during machining. Unlike mounting cutting tools directly on equipment, these holders allow quick installation and removal and greatly extend the service life of cutting fixtures.
