Kennametal 4175952 Grooving Insert NR3047 KCU10 Solid Carbide

Product Description

The KENNAMETAL 4175952 is a solid carbide grooving insert designed for precision turning and grooving operations on CNC lathes and turning centers. Manufactured in the Top Notch series, this left-hand insert carries a KCU10 grade designation and an AlTiN coating applied via PVD process. The AlTiN finish improves heat resistance and tool life when cutting ferrous and hardened materials. With a cutting width of 2.39 mm and a maximum depth of cut of 3.81 mm, this insert suits fine grooving and parting applications where dimensional accuracy is critical. Machinists and toolroom technicians working in production or job-shop environments are the primary users.

This insert is suited for external grooving and recessing operations on lathes handling small to medium workpieces. The full-radius geometry with a corner radius of 1.19 mm (0.0469 inches) produces a consistent groove profile. The clamp-style holding method pairs with compatible Top Notch toolholders. Typical applications include groove turning on steel, cast iron, and similar ferrous alloys where the KCU10 grade and AlTiN coating deliver consistent edge performance across repeat cuts.

Key Features

• Solid carbide construction, KCU10 manufacturer grade for wear resistance in ferrous machining
• AlTiN coating via PVD process for elevated heat resistance and extended tool life
• Left-hand insert orientation for specific toolholder and cut-direction compatibility
• Full radius geometry with 1.19 mm corner radius for consistent groove profile
• Clamp-style insert holding for secure seating in Top Notch series toolholders
• Cutting width of 2.39 mm and max depth of cut range of 3.00 to 4.00 mm for fine grooving work

Compatibility

Designed for use with Top Notch series clamp-style grooving toolholders that accept the NR3047 insert size. The MSC/Manufacturer cross-reference number is NR3047R/L. Verify toolholder hand orientation and insert seat dimensions before installation.

Installation Notes

Installation is performed by a qualified machinist or toolroom technician. Power down and lock out the machine spindle before seating or removing any insert. Use the correct clamp screw torque as specified by the toolholder manufacturer documentation — do not estimate. Inspect the insert pocket and clamp for chips or damage before installing a new insert to ensure proper seating and safe operation.
