Kennametal 1114270 Grooving Insert NRP3062K KC730 Carbide

Product Description

The KENNAMETAL 1114270 is a solid carbide grooving insert in the Top Notch series, designed for precision grooving and parting operations on CNC lathes and turning centers. Manufactured in the NRP3062K style with a KC730 grade and a PVD-applied TiN finish, this left-hand insert delivers consistent edge integrity and wear resistance in demanding metal-cutting environments. It features a 3.18 mm cutting width, a maximum depth of cut of 3.81 mm, and a full corner radius of 1.59 mm. The positive rake geometry and 5-degree rake angle reduce cutting forces and help control chip formation. Machinists and CNC operators working in production turning applications install this insert as a direct, high-performance tooling component.

This insert is suited for grooving, undercutting, and parting operations on ferrous and non-ferrous workpiece materials falling within material grades C2, C3, and C4. The KC730 carbide grade with TiN coating is particularly effective in interrupted cuts and moderate-speed turning applications. Its K chip breaker geometry supports chip control in medium to finish-depth grooves. The Top Notch series system is a common platform on production turning setups where repeatable insert indexing and secure clamping are required.

Key Features

• Full corner radius of 1.59 mm for smooth groove floor geometry
• KC730 solid carbide grade with PVD TiN finish for extended wear life
• Positive rake at 5 degrees reduces cutting forces and heat generation
• K chip breaker design supports chip control in grooving and parting cuts
• Left-hand orientation for compatible Top Notch series toolholders

Compatibility

Designed for use in KENNAMETAL Top Notch series toolholders configured for NRP-style grooving inserts with left-hand orientation and a 3062 insert size designation.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician with the machine powered down and all axes at a safe home position before insert change. Seat the insert fully into the Top Notch toolholder pocket and secure the clamping mechanism according to the toolholder manufacturer torque specifications. Inspect the insert seating surface and clamp for debris before securing. Verify left-hand orientation and correct insert size before resuming operations.
