Kennametal 1796090 Threading Insert NTP2R KC5010 Carbide

Product Description

The KENNAMETAL 1796090 is a carbide threading insert in the Top Notch series, designed for precision thread-turning operations on CNC lathes and manual turning centers. Coated with TiAlN via a PVD process, this insert handles both internal and external threading on a partial profile 60-degree thread form. It is sized for right-hand cuts and covers an external pitch range of 0.70 to 3.00 mm (8 to 36 TPI) and an internal pitch range of 1.25 to 3.50 mm (7 to 20 TPI). The KC5010 grade carbide substrate delivers wear resistance suited to steel and cast iron applications. Machinists and CNC programmers specify this insert for high-volume threading in production environments.

This insert fits turning and threading operations requiring a partial profile 60-degree thread standard, accommodating both internal and external thread types in a single insert geometry. The NTP2R style is matched to Top Notch toolholders. Typical applications include threading on ferrous workpieces across a wide pitch range, making it suitable for job shops and production facilities running mixed threading schedules. The insert is sold individually with a minimum order quantity of 5 units.

Key Features

• TiAlN finish applied via PVD process for improved surface hardness and heat resistance
• Handles both internal and external threading from a single insert geometry
• External pitch range: 0.70 to 3.00 mm (8 to 36 TPI)
• Internal pitch range: 1.25 to 3.50 mm (7 to 20 TPI)
• Partial profile 60-degree included angle covers unified and metric thread forms
• Corner radius of 0.1 mm (0.004 inches) for precise thread root definition

Compatibility

Designed for use with Top Notch series threading toolholders accepting NTP2R insert style inserts. Verify toolholder designation against the Top Notch insert size 2 specification before ordering.

Installation Notes

Threading inserts are installed and replaced by machinists using the appropriate torx or hex key as specified by the toolholder manufacturer. Ensure the machine spindle is fully stopped and the toolholder is securely mounted before seating or removing the insert. Confirm insert orientation matches the right-hand designation before engaging the workpiece. Follow the toolholder manufacturer's clamping torque guidance to avoid insert fracture or movement during the cut.
