BT50 Boring Toolholders

V-Flange BT 50 Tool Holders


V Flange CAT 40 Diagram

Boring depth (BD) is tool length plus boring head.

Features

  • Exceed industry standards for taper accuracy and concentricity
  • Two offset axial tapered locking screws maximize rigidity and allow fast tool changes
  • Reducers allow different size boring heads to be used with the same toolholder

Modular Coupling System

Allows heads to be changed without removing tools from the spindle. Two offset center lock screws apply maximum tightening force between the boring head and the toolholder for increased rigidity and enhanced vibration dampening characteristics.
