Kennametal 1152082 Grooving Insert NG3M450K KC730 4.5mm

Product Description

The KENNAMETAL 1152082 is a solid carbide grooving insert with a TiN finish, designed for precision grooving and parting operations on CNC lathes and turning centers. It carries the NG3M450K designation within the Top Notch series and is coated via a PVD process for wear resistance. The insert delivers a 4.5 mm cutting width, a maximum depth of cut of 3.81 mm, and a positive rake angle of 10 degrees, making it well suited for consistent chip control in medium to semi-finish grooving applications. The KC730 grade falls within the C2, C3, and C4 material grades, targeting a range of steel and alloy machining applications. Machinists and CNC operators in production and job-shop environments typically specify this insert.

This insert is intended for right-hand grooving operations on lathes and turning centers using Top Notch compatible toolholders. With a 0.32 mm corner radius, a 55-degree included angle, and a K-style chip breaker, it is suited for controlled chip evacuation during groove profiling. The metric insert size designation is 3M450, and the measurement type is metric. It is a single-use, non-multi-use insert without a full radius nose geometry.

Key Features

• 4.5 mm cutting width with a maximum depth of cut of 3.81 mm
• KC730 grade solid carbide with PVD-applied TiN coating for extended tool life
• Positive rake angle of 10 degrees for reduced cutting forces
• K-style chip breaker for controlled chip formation in grooving operations
• 0.32 mm corner radius and 55-degree included angle for precise groove geometry
• Right-hand insert orientation for standard OD grooving setups

Compatibility

Designed for use with Top Notch series compatible grooving toolholders that accept NG-style inserts. Verify toolholder seat geometry and insert pocket dimensions before installation.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Power down and lock out the machine before seating or replacing the insert. Use the appropriate torx or hex key to secure the insert clamp to the manufacturer-specified procedure without over-torquing the clamping screw. Inspect the insert pocket and clamping components for wear or debris before seating a new insert.
