Kennametal 1161883 CCGT2151LF KC730 Turning Insert

Product Description

The KENNAMETAL 1161883 is a solid carbide turning insert with a TiN (titanium nitride) PVD coating, designed for precision finishing and light machining operations on steel, stainless steel, cast iron, and superalloys. Identified by industry standard code CCGT2151LF, this insert features an 80-degree diamond (rhombic) shape, a neutral hand orientation, and a positive rake and side clearance geometry. The inscribed circle measures 0.25 inches, the corner radius is 0.0156 inches (1/64 inch), and insert length is 0.2539 inches (6.45 mm). It is held in place via screw-on mounting and delivers two usable cutting edges per insert. The KC730 grade provides high to moderate wear resistance combined with toughness across its target material range.

This insert is suited for turning, facing, and boring operations in CNC and manual lathe applications. The LF chip breaker geometry is optimized for finishing and light machining passes where surface finish and dimensional accuracy are the priority. Primary workpiece materials include steel (P), stainless steel (M), and cast iron (K), with secondary suitability for superalloys and titanium (S, M). The positive cutting geometry reduces cutting forces, making it a practical choice for slender workpieces or setups where vibration control is important. Licensed machinists and toolroom technicians are the typical end users for this class of insert.

Key Features

• CCGT2151LF geometry with 80-degree diamond shape and positive rake for reduced cutting forces
• KC730 grade with TiN PVD coating for high wear resistance across steel, stainless steel, and cast iron
• LF chip breaker optimized for finishing and light machining passes
• Screw-on insert holding method for secure, repeatable seating in compatible toolholders
• Two cutting edges per insert; honed cutting edge style for consistent edge integrity
• Multi-use application: turning, facing, and boring

Compatibility

Designed for use in screw-on style toolholders accepting CCGT2151 inserts per ANSI and ISO standards (ISO size code 060204). Confirm toolholder pocket geometry and screw hole diameter (0.1142 inches) before installation.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician with the machine powered down and all energy sources locked out per applicable OSHA lockout/tagout procedures. Seat the insert fully into the toolholder pocket before tightening the clamping screw to the toolholder manufacturer's specification. Inspect the cutting edge and coating condition before each use; do not use an insert that shows edge chipping or coating delamination. Handle carbide inserts with care to avoid impact damage to the cutting edges.
