Sandvik Coromant 5731455 Indexable Turning Toolholder

Product Description

The SANDVIK COROMANT 5731455 is a DVJNR-style indexable turning toolholder designed for precision facing operations on CNC lathes and turning centers. Built with a wedge insert-holding method and a negative rake angle of -4 degrees, it secures VNMG 332 inserts with consistent clamping force across repeated index cycles. The 1.25-inch square shank and 6-inch overall length suit medium to large turning setups where rigid tool engagement and predictable insert seating are critical. The toolholder is constructed from steel and configured for right-hand cutting. It is sold individually and can serve as a multi-use tool across compatible turning applications.

This toolholder is suited for facing operations on ferrous and non-ferrous workpieces in both production and job-shop turning environments. The DVJNR geometry and negative rake make it a practical choice for shops running moderate to heavy depths of cut where insert security under load is a priority. The wedge clamping system is widely used in high-volume lathe work where quick insert changes and repeatable tool nose positioning are required. Machinists and CNC setup technicians handling external turning and facing work will recognize this as a standard T-Max P series platform configuration.

Key Features

• DVJNR toolholder style with right-hand cutting orientation
• Wedge insert-holding method for secure, repeatable clamping of VNMG 332 inserts
• Negative rake angle of -4 degrees suited for robust facing cuts
• 1.25-inch square shank (1-1/4 inch width and height) for rigid machine interface
• 6-inch overall length with 1.83-inch head length for clearance in standard lathe setups
• Multi-use tool designation allows application across compatible turning operations
• Steel construction for durability under continuous machining loads

Compatibility

Designed to accept VNMG 332 inserts with a 3/8-inch inscribed circle. Belongs to the T-Max P series platform. Verify insert grade and geometry selection against the specific workpiece material and cutting parameters before use.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the machine spindle is fully stopped and the control is in an E-stop or lockout state before mounting or removing the toolholder from the turret or tool block. Confirm shank seating and turret bore compatibility before torquing clamp bolts. Follow the machine tool manufacturer's torque specifications for the turret clamping screws; do not use impact tools on fine-thread clamp hardware.
