Kennametal 4114348 Grooving Insert KCU25 Solid Carbide

Product Description

The KENNAMETAL 4114348 is a solid carbide grooving insert in the A4 series, designed for external grooving operations on CNC lathes and turning centers. Coated with AlTiN via a PVD process, it operates in the KCU25 manufacturer grade, which targets a broad range of steel, stainless, and cast iron workpiece materials. The insert carries a neutral hand orientation and features a GMN chip breaker geometry. Cutting width is 0.1594 inches, maximum depth of cut is 0.1339 inches, and the full-radius corner radius measures 0.0797 inches. Machinists and CNC operators working in production or job-shop environments will find this insert suitable for consistent, repeatable groove profiles.

The 4114348 is suited for grooving and parting applications on turning equipment where a neutral, full-radius insert style is required. The A4 insert seat size and GMN chip breaker make it appropriate for moderate feed and depth conditions across a range of ferrous and non-ferrous materials. It is rated as a multi-use tool, supporting applications beyond straight grooving where the geometry fits. This insert is sold individually but carries a minimum order quantity of 10 units, making it a standard replenishment item for shops running A4-series toolholders.

Key Features

• AlTiN coating applied via PVD process for elevated heat resistance and extended tool life
• GMN chip breaker geometry for controlled chip formation in grooving operations
• Full radius profile with 0.0797 inch corner radius for smooth groove floor finish
• Neutral hand orientation compatible with straight-plunge grooving setups
• Multi-use designation supports grooving, profiling, and face grooving where geometry applies
• KCU25 grade targets a broad material range including steels and cast irons

Compatibility

Designed for use in A4-series insert seats with an insert seat size of 4. Compatible with toolholders specifying the A4 insert style. Catalog reference number A4R0405M04U00GMN may be used to cross-reference equivalent holder and insert pairings.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Power down and lock out the machine spindle before seating or removing inserts. Use the appropriate torx or hex key as specified by the toolholder manufacturer to achieve proper clamping force without over-torquing the insert screw. Inspect the insert pocket and seating surface for chips or debris before installing a new insert.
