4495-D V-Groove Tool Holder for Round Boring Bars (TYPE D) BISON

The professional 4495-D (Type D) Tool Holder is a high-precision lathe accessory uniquely engineered for holding cylindrical and round shank tools. Featuring a specialized V-groove (V-prism) design, it delivers multi-point uniform clamping force around round boring bars, locking them firmly into place and eliminating any axial twist or deflection during heavy internal turning operations.

Drop-forged from premium structural tool steel, this block provides excellent vibration-dampening capabilities, thereby ensuring rigid setups, tighter operating tolerances, and finer workpiece surface finishes. As shown in the technical specifications from image_887a49.png, the tool holder is available in an array of dimensional variants to seamlessly integrate with your existing quick-change tool post (QCTP) setup.
