Kennametal 1795791 Threading Insert NTF2R KC5025 Carbide

Product Description

The KENNAMETAL 1795791 is a carbide threading insert in the Top Notch series, designed for precision thread-cutting on both internal and external applications. Manufactured to the NTF insert style with a KC5025 grade substrate, it features a PVD-applied TiAlN finish that supports extended tool life in demanding threading operations. The insert covers a partial profile 60-degree thread standard and handles external pitches from 0.60 to 1.75 mm (14 to 44 TPI) and internal pitches from 1.00 to 2.00 mm (12 to 24 TPI). It is a right-hand insert with a corner radius of 0.08 mm and a tip-to-top dimension of 2.79 mm. Machinists and CNC operators working in production or job-shop environments install this insert into compatible Top Notch toolholders.

This insert is suited for threading operations on a range of materials classified under material grades C2 and C6, covering a broad spectrum from cast irons to non-ferrous alloys. It is used in both internal bore threading and external OD threading setups, making it versatile across turning centers and manual lathes. The partial profile geometry allows a single insert to cover multiple thread pitches within its range, reducing the need for dedicated pitch-specific tooling. Typical applications include production threading of fittings, fasteners, and precision components in industrial machining environments.

Key Features

• PVD TiAlN coating for wear resistance and thermal stability in threading cuts
• Covers external pitches 0.60 to 1.75 mm (14 to 44 TPI) and internal pitches 1.00 to 2.00 mm (12 to 24 TPI)
• Partial profile 60-degree thread form accommodates multiple pitch ranges with one insert
• Right-hand cutting geometry in NTF insert style for Top Notch series toolholders
• Corner radius of 0.08 mm (0.0031 inches) for controlled thread root form
• Carbide substrate with KC5025 grade for toughness and edge integrity

Compatibility

Designed for use in Top Notch series toolholders accepting NTF2R insert style, size 2. Verify toolholder seat geometry and clamping method before installation.

Installation Notes

Threading inserts of this type are installed and replaced by machinists or tooling technicians on CNC turning centers or manual lathes. Always index or replace the insert with the machine powered down and the spindle fully stopped. Use the appropriate torque wrench for the clamping screw as specified by the toolholder manufacturer, and inspect the insert seat for chips or debris before seating the insert. Handle carbide inserts with care to avoid edge chipping prior to use.
