Kennametal 1163034 Turning Insert T220F K68 Solid Carbide

Product Description

The KENNAMETAL 1163034 is a solid carbide turning insert designed for precision metal-cutting operations on CNC lathes and turning centers. Manufactured in the T220F geometry with grade K68, this uncoated insert features a triangular shape with a 60-degree included angle, a 0.25-inch inscribed circle, and a 0.004-inch corner radius. The bright, uncoated carbide surface suits applications where coating adhesion would hinder chip flow or where sharp-edge integrity is critical. With a neutral hand orientation and screw-on holding method, it mounts securely in compatible toolholders for repeatable positioning. Licensed machinists and CNC operators working in job shops or production environments install this insert for finishing and light roughing passes.

This insert is suited for turning stainless steel, cast iron, aluminum, and other non-ferrous materials, corresponding to ISO material groups M, K, and N. The F chip breaker geometry and positive rake promote controlled chip formation at moderate-to-high cutting speeds. It is appropriate for light-duty to medium-duty turning operations where wear resistance is the primary requirement. The maximum depth of cut is 1.25 mm (0.0492 inches), making it best applied in finishing and semi-finishing passes rather than heavy stock removal. CNC machinists and tool-and-die professionals are the primary end users.

Key Features

• Grade K68 solid carbide with bright, uncoated finish for sharp cutting-edge integrity
• T220F geometry: 60-degree triangle insert with 0.004-inch corner radius
• F chip breaker promotes controlled chip formation during finishing cuts
• Positive rake with negative side clearance for stable screw-on clamping
• Maximum depth of cut of 1.25 mm for finishing and semi-finishing passes
• Compatible with ISO material groups M (stainless steel), K (cast iron), and N (aluminum and non-ferrous)

Compatibility

Designed for use with screw-on toolholders accepting ANSI insert code T220 and ISO insert code T110301. Compatible with workpiece materials classified under ISO codes P, M, K, N, and S per the grade characteristics stated by the manufacturer.

Installation Notes

Installation is performed by qualified machinists or CNC operators following standard turning insert replacement procedures. Power down and lock out the machine spindle before handling inserts. Use the manufacturer-specified torque driver for the clamping screw to avoid over-torquing the carbide body. Inspect the insert pocket and seating surface for chips or debris before seating the new insert.
