Kennametal 4175932 Threading Insert 3010 Njp KCU10 16 Tpi

Product Description

The KENNAMETAL 4175932 is a solid carbide threading insert designed for external thread cutting on UNJ-standard workpieces. Built to NJP style geometry in the Top Notch series, it cuts right-hand external threads at 16 TPI with a 60-degree included angle. The insert carries a KCU10 grade designation and an AlTiN finish applied via PVD coating, providing thermal resistance and extended tool life in demanding cutting conditions. At 0.022 pounds, it is a precision-ground, single-piece carbide insert intended for use in compatible Top Notch threading toolholders. Machinists and CNC operators working in aerospace, defense, and precision manufacturing will find this insert suited to tight-tolerance UNJ thread profiles.

This insert is intended for external threading operations on materials where UNJ thread standards are specified, commonly found in aerospace fastener and structural applications. The NJP style geometry and 16 TPI pitch make it appropriate for threading passes on shafts, fittings, and precision components. The AlTiN PVD coating performs well in dry or near-dry cutting environments and on harder ferrous and exotic alloy workpieces. It is sized at 3010 and fits Top Notch series threading toolholders designed for that insert size.

Key Features

• Solid carbide construction with KCU10 grade for wear resistance in threading applications
• AlTiN finish via PVD coating for thermal stability and extended tool life
• NJP style geometry engineered for UNJ external thread profiles
• 16 TPI external pitch with 60-degree included angle for precise thread form
• Right-hand cut orientation; 3010 insert size for Top Notch series holders
• Corner radius of 0.0099 inches (0.25 mm) for controlled thread root geometry

Compatibility

Designed for use in Top Notch series threading toolholders accepting 3010 size NJP style inserts. Cuts UNJ standard external right-hand threads at 16 TPI.

Installation Notes

Threading inserts should be installed by a qualified machinist or CNC operator with the machine fully powered down and the spindle locked before insert change. Use the appropriate torque wrench and insert screw specified for the Top Notch toolholder to avoid cracking the carbide substrate. Inspect the insert seat and clamping surfaces for chips or debris before seating the insert. Do not exceed the recommended depth of cut or feed rate specified for the toolholder and workpiece material combination.
