Kennametal 1114630 Grooving Insert NRP3031 K68 Carbide

Product Description

The KENNAMETAL 1114630 is a solid carbide grooving insert in the Top Notch series, designed for precision grooving and parting operations on CNC lathes and turning centers. This right-hand insert carries a K68 grade uncoated carbide substrate with a positive rake angle of 5 degrees, making it well suited for cutting non-ferrous materials, cast iron, and other abrasive workpiece materials where sharp, clean cutting action is required. The insert measures 1.58 mm in cutting width with a maximum depth of cut of 2.39 mm, and features a full radius corner geometry with a corner radius of 0.79 mm for consistent groove profiles.

This insert is used in light to medium grooving applications on manual and CNC turning equipment, typically in production and job shop environments. The Top Notch series is a recognized tooling platform for external grooving and cutoff work. It is installed and changed out by machinists and CNC operators as part of routine insert indexing. The uncoated bright finish is preferred for applications where coating adhesion to the chip or workpiece material would be a concern, such as when machining aluminum, copper alloys, and similar non-ferrous metals.

Key Features

• Solid carbide K68 grade substrate for wear resistance in abrasive and non-ferrous applications
• 1.58 mm cutting width for precise, narrow groove profiles
• Maximum depth of cut of 2.39 mm, rated for the 2.00 to 3.00 mm depth range
• Full radius corner geometry with 0.79 mm corner radius for smooth groove bottoms
• Positive 5-degree rake angle reduces cutting forces and improves chip flow
• Uncoated bright finish suitable for non-ferrous and abrasive material cutting

Compatibility

Designed as an OEM-style replacement insert for Top Notch series grooving toolholders that accept NRP-style inserts in size 3031.

Installation Notes

Insert installation and indexing should be performed by a qualified machinist or CNC operator with the machine powered down, spindle locked, and all moving axes secured. Use the appropriate Top Notch insert clamp and torque the clamping screw only with the designated wrench to avoid insert seat damage. Inspect the insert pocket and seating surface for chips or debris before seating the new insert. Follow all applicable shop safety procedures and machine manufacturer guidelines when changing cutting inserts.
