Sandvik Coromant 7572085 Indexable Turning Toolholder

Product Description

The SANDVIK COROMANT 7572085 is a right-hand indexable turning toolholder in the T-Max QS series, designed for screw-clamp retention of CNMG 120408 inserts. The toolholder features a 1 inch by 1 inch steel shank with a negative rake angle of -6 degrees, making it suited for stable, high-precision turning operations on CNC lathes and turning centers. At 1.219 pounds, the holder is built for rigid clamping in the QS-PCLNR 16 4C configuration, which positions the insert at a compound negative cutting geometry. Machinists and tooling technicians working with external turning applications will find this holder a direct fit within the T-Max QS quick-change system.

This toolholder is intended for external turning operations where consistent insert positioning and repeatable tool changes are required. The QS quick-change interface reduces setup time on turning centers by allowing insert and holder swaps without removing the entire toolholder assembly from the turret. It is a single-use, non-multi-purpose holder designated for right-hand cutting direction. Typical applications include general-purpose turning of steel, cast iron, and similar workpiece materials using CNMG-style inserts.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Power down and lock out the machine spindle before seating or removing the toolholder in the turret. Verify insert seating and screw torque according to the machine tool and tooling system documentation before resuming cuts. Do not exceed the rated depth of cut or feed rate for the insert grade in use.
