Seco 00071940 Svvb Neutral Turning Toolholder 0.75in Shank

Product Description

The SECO 00071940 is a neutral-hand SVVB-style indexable turning toolholder designed for use on CNC and manual lathes in metal-cutting operations. It accepts VB..331. series inserts secured by a screw-lock clamping method, providing repeatable positioning and rigid insert retention during turning passes. The shank measures 0.75 inches wide by 0.75 inches tall with an overall length of 4.5 inches. The toolholder is manufactured from steel and is rated for universal primary workpiece material compatibility, covering common material groups including ferrous, non-ferrous, and exotic alloys. This style of toolholder is typically installed by machinists and CNC operators in production and job-shop turning environments.

The 00071940 is suited for external turning applications on both manual and CNC lathes where a neutral cutting direction is required. The 0-degree rake angle and neutral hand orientation allow the tool to be used at centerline without offset bias, making it adaptable to a variety of turning setups. The screw-lock holding method is standard in production environments where quick insert changes and consistent edge indexing are priorities. Compatible insert size code is VB33 and back-of-bar to cutting edge distance is 0.375 inches, which informs tool centerline setup during installation.

Key Features

• SVVB toolholder style with neutral hand orientation for centerline turning without directional bias
• Screw-lock insert clamping for secure, repeatable insert indexing
• Accepts VB..331. series inserts with a 0.375-inch inscribed circle diameter
• 0-degree rake angle supports a wide range of workpiece materials
• Steel construction for rigidity and durability in production turning applications
• Compact 4.5-inch overall length suits tight turret clearances on smaller lathes

Compatibility

Designed to accept VB..331. series inserts with compatible insert size code VB33. Rated for universal primary workpiece material groups including H, K, M, N, P, and S material codes, covering hardened materials, cast iron, stainless, non-ferrous, steel, and heat-resistant superalloys.

Installation Notes

Installation is performed by machinists or CNC setup technicians. Ensure the machine spindle is fully stopped and all axis motion is disabled before mounting or removing the toolholder from the turret. The shank must be clamped to the manufacturer-specified torque using the appropriate toolholder fasteners for the turret type in use. When indexing or replacing inserts, use the correct screw-lock torx or hex key as specified for VB..331. insert screws to avoid stripping the clamping screw.
