Kennametal 1796112 Threading Insert NTP4L KC5010 Tialn

Product Description

The KENNAMETAL 1796112 is a carbide threading insert designed for both internal and external thread cutting operations. Finished with a TiAlN PVD coating, it carries the KC5010 grade designation and conforms to a 60-degree partial profile thread form. The left-hand NTP4L insert style seats into Top Notch series toolholders. It covers an external pitch range of 1.25 to 6.25 mm (4 to 20 TPI) and an internal pitch range of 2.00 to 6.25 mm (4 to 12 TPI), making it a versatile choice for machinists threading a wide range of fastener standards on turning centers and manual lathes.

This insert is suited for production and job-shop environments where consistent thread form and tool life are critical. The KC5010 grade with PVD TiAlN coating is engineered for threading ferrous and non-ferrous workpiece materials classified under material grades C3 and C4. Typical applications include external threading on shafts and studs as well as internal threading in bored features, installed by machinists and CNC operators in both high-volume and low-volume turning operations.

Key Features

• TiAlN PVD finish coating for wear resistance and extended tool life
• 60-degree partial profile form covers both internal and external threading in a single insert
• Left-hand cutting geometry (NTP4L insert style) for Top Notch series toolholders
• External pitch range: 1.25 to 6.25 mm (4 to 20 TPI)
• Internal pitch range: 2.00 to 6.25 mm (4 to 12 TPI)
• Compact insert size 4 with a corner radius of 0.17 mm (0.0065 inches) for precise thread root definition

Compatibility

Designed for use with Top Notch series threading toolholders that accept the NTP insert style. Confirm toolholder seat geometry and clamping system compatibility before installation.

Installation Notes

Indexable threading inserts should be installed and indexed by a qualified machinist following the toolholder manufacturer's seating and clamping torque guidelines. Ensure the machine spindle is at a full stop before changing or indexing the insert. Verify insert orientation and hand of cut match the programmed threading cycle direction before engaging the workpiece. Consult applicable shop safety standards and machine tool documentation for proper handling of carbide inserts.
