Kennametal 7090635 Vnmg Turning Insert Altin Carbide

Product Description

The KENNAMETAL 7090635 is a VNMG-style indexable turning insert designed for precision metal cutting on CNC lathes and turning centers. Built from carbide substrate in a diamond (V) insert shape with a 35-degree included angle, this insert carries an AlTiN coating and KENNAMETAL grade KCU10B for elevated heat resistance and wear life in demanding turning operations. The corner radius measures 0.80 mm (0.0313 inches), and with four cutting edges per insert, it delivers extended tool life per unit. Licensed machinists and CNC operators working in production turning environments are the primary users of this insert.

This insert is suited for external and internal turning applications where a sharp, narrow-angle diamond insert geometry is required for profiling, shoulder turning, or contour cuts. The MS chip breaker geometry is designed to control chip flow across a range of depths of cut and feed rates, making it appropriate for both roughing and finishing passes depending on setup. It fits neutral-hand toolholders accepting VNMG 432 inserts with a 0.5000-inch (12.70 mm) inscribed circle.

Key Features

• VNMG insert style with V-shape (35-degree included angle) for profiling and contour turning
• AlTiN coating on KCU10B carbide grade for heat and abrasion resistance
• 0.80 mm corner radius for controlled surface finish and edge strength
• Four indexable cutting edges per insert maximize cost efficiency
• MS chip breaker geometry for active chip control across varied cutting conditions
• Neutral hand orientation for broad toolholder compatibility

Compatibility

Designed for use in VNMG 432 neutral-hand toolholders accepting a 0.5000-inch inscribed circle. Verify toolholder pocket tolerance and seat dimensions before installation.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Ensure the machine spindle is fully stopped and the toolholder is secured in the turret before indexing or replacing the insert. Use the correct torque wrench for the clamping screw to avoid insert cracking or seat damage — refer to the toolholder manufacturer specifications for torque values. Inspect the insert pocket and seat for debris or wear before seating the new insert.
