Kennametal 1796107 Threading Insert NTP3R KC5410 Carbide

Product Description

The KENNAMETAL 1796107 is a carbide threading insert in the Top Notch series, designed for precision thread-cutting on CNC lathes and turning centers. Featuring a titanium diboride (TiB2) finish applied via PVD coating, the insert delivers a hard, low-friction surface that extends tool life in demanding threading operations. It carries a partial profile 60-degree thread form and is suited for right-hand cutting. The KC5410 grade positions it for general-purpose threading in materials classified as C3 and C4. External pitch range is 1.25 to 4.00 mm (6 to 20 TPI) and internal pitch range is 2.00 to 5.00 mm (5 to 12 TPI), covering a wide span of common thread sizes in a single insert style.

This insert is used in production and job-shop turning environments where both internal and external threading operations are required. The NTP3R style fits Top Notch-compatible toolholders and is appropriate for threading ferrous and non-ferrous materials where a 60-degree partial profile form is specified. Machinists and CNC operators working with metric and unified thread standards will find the dual pitch coverage useful for reducing changeovers on mixed-threading jobs.

• Internal pitch: 2.00 to 5.00 mm (5 to 12 TPI)
• Right-hand cutting orientation
• KC5410 grade, material classification C3 and C4

Compatibility

Designed for use with Top Notch series NTP3R-compatible toolholders. Consult the toolholder documentation to confirm proper insert seat geometry before installation.

Installation Notes

Threading inserts of this type are seated and clamped by a qualified machinist or CNC tooling technician. Ensure the machine spindle is fully stopped and the turret is in a safe index position before changing inserts. Confirm the insert is fully seated in the pocket and the clamping mechanism is engaged per the toolholder specification before resuming operations. Inspect the insert and pocket for wear or damage at each tool change interval.
