Kennametal 1160330 TNMG332K KC850 Turning Insert

Product Description

The KENNAMETAL 1160330 is a TNMG332K KC850 grade solid carbide turning insert designed for precision external and internal turning operations on CNC and manual lathes. The insert features a multilayer CVD coating of TiC, TiCN, and TiN applied over a carbide substrate, delivering a balance of wear resistance and toughness suited to interrupted and continuous cuts. At 0.375 inches inscribed circle diameter, 0.6496 inches in length, and a 0.0312-inch corner radius, this triangular insert fits standard KENLOC toolholders with clamp and pin retention. Licensed machinists and CNC operators install this insert in production and job-shop turning environments.

This insert is rated for use on steel (P), stainless steel (M), cast iron (K), and special or super alloys (S) workpiece materials, making it a versatile choice across material grades C5 and C6. The K chip breaker geometry suits moderate to high toughness cutting demands. Maximum depth of cut is 1.25 mm (approximately 0.049 inches). The neutral hand orientation allows use on both right- and left-hand tooling setups, and the negative side clearance (clearance code N, tolerance code M) ensures secure seating in the pocket.

Key Features

• CVD multilayer coating: TiC, TiCN, and TiN for extended tool life across varied workpiece materials
• 60-degree triangular insert shape (TNMG) with negative rake geometry for rigid, stable cutting
• KC850 grade balances moderate wear resistance and toughness for steel, stainless, cast iron, and super alloys
• K chip breaker geometry controls chip formation at moderate to high feed rates
• Clamp and pin retention compatible with KENLOC series toolholders
• Neutral hand orientation works in right- and left-hand holder configurations

Compatibility

Designed as an OEM-style replacement insert for KENLOC series toolholders. ANSI insert code TNMG332; ISO insert code TNMG160408. Compatible with toolholder pockets dimensioned for a 0.375-inch inscribed circle, 0.1875-inch insert thickness, and 0.150-inch hole diameter.

Installation Notes

Insert replacement is performed by licensed machinists or CNC technicians. Power down and lock out the machine before changing inserts. Inspect the toolholder pocket and clamping pin for wear or debris before seating the new insert. Torque clamping screws according to the toolholder manufacturer specifications - do not estimate by feel on high-speed applications.
