Seco 00071946 Svvb Neutral Turning Toolholder 1 in Shank

Product Description

The SECO 00071946 is a neutral-hand SVVB-style indexable turning toolholder designed for external turning operations on CNC lathes and manual turning centers. Built on a 1 inch by 1 inch steel shank with an overall length of 6 inches, it accepts VB..33. series inserts secured by a screw-lock clamping method. The neutral cutting direction and 0-degree rake angle make it suitable for straight turning passes where neither left- nor right-hand orientation is required. Licensed machinists and CNC operators working in job shops or production turning cells are the primary installers of this toolholder.

This toolholder is rated for universal primary workpiece material compatibility, covering material codes H, K, M, N, P, and S. That range encompasses cast iron, non-ferrous alloys, stainless steel, carbon and alloy steels, and heat-resistant superalloys, making it a practical multi-material option for general turning applications. It is not configured for coolant-through delivery. The back-of-bar to cutting edge distance is 0.5 inches, and the head length measures 1.19 inches, providing predictable tool nose positioning for setup.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Before mounting, confirm the machine spindle is in an e-stop or locked-out state per OSHA lockout/tagout procedures. Seat the shank fully in the turret or tool block and torque the clamping bolts to the machine manufacturer's specification. Verify insert seating and screw torque against the insert manufacturer's guidelines before initiating a cut.
