Kennametal 1114369 Threading Insert 16 Tpi Left Hand KC730

Product Description

The KENNAMETAL 1114369 is a carbide threading insert in the Top Notch series, designed for external thread turning on CNC lathes and turning centers. The insert carries a Titanium Nitride (TiN) finish applied via PVD coating, which improves wear resistance and tool life on ferrous and non-ferrous materials. It is configured for left-hand cutting with a 60-degree included angle and a 16 TPI pitch, conforming to the UNJ thread standard. The KC730 grade carbide substrate and C2-C4 material grade range make this insert well suited for general-purpose threading operations where consistent thread form and edge integrity are required. Machinists and toolroom operators working on precision threaded components select this insert for reliable single-pass or multi-pass threading cycles.

This insert is intended for external threading applications on turning equipment. The NJP insert style and 3010 insert size place it in KENNAMETAL Top Notch toolholders designed for that geometry. Left-hand orientation suits configurations where the spindle rotation or toolholder approach requires a left-hand cutting edge. Typical applications include threading aerospace, hydraulic, and industrial fastener components where UNJ thread forms are specified. The 0.25 mm corner radius supports clean thread root geometry at 16 TPI.

Key Features

• Left-hand cutting configuration for compatible Top Notch toolholders
• 16 TPI external pitch conforming to the UNJ thread standard
• 60-degree included angle for standard unified thread form geometry
• Insert size 3010 with a corner radius of approximately 0.0099 inches (0.25 mm)
• Thickness of 0.1949 inches (4.95 mm) for rigid seating in the pocket

Compatibility

Designed for use in KENNAMETAL Top Notch series toolholders accepting the NJP insert style in size 3010. Verify toolholder insert pocket geometry and hand orientation before installation.

Installation Notes

Threading inserts of this type are installed and replaced by machinists or toolroom personnel on CNC or manual turning equipment. Power down and lock out the machine before accessing the turret or toolholder pocket. Use the correct torque wrench and clamp screw specified by the toolholder manufacturer to seat the insert without cracking the carbide. Inspect the pocket and clamp for wear or debris before seating a new insert.
