Kennametal 1114887 Grooving Insert NG2062K KC850

Product Description

The KENNAMETAL 1114887 is a solid carbide grooving insert designed for external grooving and turning operations on CNC lathes and turning centers. It carries the NG2062K geometry in the KC850 grade, featuring a CVD-applied multilayer coating of TiC, TiCN, and TiN for wear resistance across a range of workpiece materials. The insert is left-hand oriented with a 1.58 mm cutting width and a maximum depth of cut of 2.79 mm. With a positive rake angle of 10 degrees and a K-style chip breaker, it promotes controlled chip flow during grooving passes. This insert is suited for use by machinists and CNC operators working in production or job-shop environments.

This insert is intended for external grooving applications on turning equipment. It fits toolholders in the Top Notch series, which is a common platform for indexable grooving systems used in both light and medium-duty metal removal. It is applicable to workpiece materials falling within the C5 and C6 material grade classifications, which cover cemented carbides and coated carbide applications on steel, stainless, and cast iron. The K chip breaker geometry is optimized for finishing and light roughing groove profiles where chip control is a priority.

Key Features

• KC850 grade solid carbide with CVD multilayer TiC, TiCN, TiN coating for extended tool life
• 1.58 mm cutting width with a maximum depth of cut of 2.79 mm
• Positive rake angle of 10 degrees reduces cutting forces during grooving
• K-style chip breaker promotes reliable chip evacuation in finishing passes
• Corner radius of 0.19 mm (0.0075 inches) for controlled groove profile
• Left-hand insert orientation for compatibility with left-hand Top Notch toolholders

Compatibility

Designed for use in Top Notch series indexable grooving toolholders. Fits systems accepting the NG insert style in size 2062. Material grade ratings of C5 and C6 indicate suitability for steel, stainless steel, and cast iron workpiece materials.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician with the machine in a locked-out, zero-energy state before indexing or replacing inserts. Use the appropriate torx or clamping key specified by the toolholder manufacturer to seat the insert securely in the pocket. Inspect the pocket and clamping components for wear or debris before seating the new insert. Do not exceed the cutting parameters recommended for the KC850 grade and the specific workpiece material being machined.
