Kennametal 1114321 Grooving Insert KC730 Carbide Tin

Product Description

The KENNAMETAL 1114321 is a solid carbide grooving insert in the Top Notch series, designed for precision grooving and parting operations on CNC lathes and turning centers. It carries a KC730 manufacturer grade with a PVD-applied TiN coating, offering a positive rake angle of 10 degrees and a right-hand cutting orientation. The insert delivers a cutting width of 2.39 mm and a maximum depth of cut of 3.81 mm, making it suitable for moderate-depth grooving passes. Machinists and CNC operators install this insert into compatible Top Notch toolholders as a precision consumable in production turning environments.

This insert is used in external grooving and profiling applications on turning centers handling materials in the C2, C3, and C4 material grade categories. Its positive rake geometry and K-style chip breaker help manage chip flow during interrupted and continuous grooving cuts. The 55-degree included angle and 0.19 mm corner radius make it appropriate for tight-tolerance groove profiles in general metalworking and production machining operations. It is sold individually but subject to a minimum order quantity of 5 units per purchase.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator with the machine powered down and in a safe, locked-out state. Seat the insert fully in the toolholder pocket and verify clamping torque per the toolholder manufacturer specifications before resuming cuts. Inspect the insert seating surface and clamp for wear or debris before each insert change. Confirm correct hand orientation and depth stop setting before taking the first pass.
