Kennametal 1159662 VNMG332P KC730 Turning Insert

Product Description

The KENNAMETAL 1159662 is a solid carbide turning insert in the KENLOC series, designated VNMG332P with manufacturer grade KC730. It features a 35-degree diamond (rhombic) insert shape, a TiN PVD coating, and a neutral hand orientation. The inscribed circle measures 3/8 inches (0.3750 inches), the corner radius is 1/32 inches (0.0313 inches), and the insert thickness is 3/16 inches (0.1875 inches). The cutting edge style is honed with a negative rake angle of 10 degrees and negative side clearance. This insert is engineered for high wear-resistance to moderate wear-resistance and toughness across steel, stainless steel, and cast iron workpiece materials. Machinists and CNC turning specialists install this insert in production and job-shop environments.

The 1159662 is suited for turning, facing, boring, back turning, and back boring operations. The P chip breaker geometry supports roughing and medium machining applications. Primary workpiece material categories include steel (P), stainless steel (M), and superalloys and titanium (S). Secondary workpiece material codes are M and S. The insert conforms to ANSI size code 332 and ISO size code 160408, making it appropriate for standard VNMG toolholders used in both manual and CNC turning centers in residential shop, commercial production, and heavy manufacturing settings.

Key Features

Compatibility

Designed as an OEM-style replacement for VNMG332P-style turning inserts used in KENLOC series toolholders conforming to ANSI and ISO standards for VNMG insert geometry.

Installation Notes

Installation is performed by machinists or CNC tool-setup technicians. Power down and lock out the machine spindle before changing inserts. Inspect the insert pocket and clamp or pin for wear or debris before seating the new insert. Do not exceed the maximum depth of cut of 0.0492 inches (1.25 mm) as specified for this insert geometry.
