Kennametal 1724414 Threading Insert KC5010 48-16 Tpi

Product Description

The KENNAMETAL 1724414 is a solid carbide laydown threading insert designed for internal threading operations. Manufactured to the LT11NRA60 insert style in the KC5010 grade, it features a TiAlN coating applied via PVD process for improved wear resistance and thermal stability at the cutting edge. The insert cuts a partial profile 60-degree thread form, covering a range of 48 to 16 threads per inch (TPI) with a pitch range of 0.50 to 1.50 mm. At 0.1260 inches thick with a 1/4-inch inscribed circle, this insert is sized for precision threading work on lathes and CNC turning centers. Machinists and toolroom technicians are the primary users.

This insert is suited for right-hand internal threading applications on CNC lathes and manual turning equipment. The partial profile 60-degree thread form makes it versatile across a wide TPI range without requiring a separate insert for each pitch. Typical applications include threading bores in ferrous and non-ferrous workpieces where consistent thread form accuracy and tool life are priorities. The KC5010 carbide grade with TiAlN PVD coating is well matched to a variety of steel and stainless steel threading operations.

Key Features

• Solid carbide construction with TiAlN PVD coating for extended tool life
• Partial profile 60-degree thread form covers 48-16 TPI in a single insert
• Right-hand orientation for standard internal threading on CNC or manual lathes
• 1/4-inch (6.35 mm) inscribed circle for secure seating in LT-style toolholders
• Corner radius of 0.0020 inches (0.05 mm) for precise thread root geometry
• Hole diameter of 0.1280 inches (3.25 mm) for positive mechanical clamping

Compatibility

Designed as an OEM-style replacement or direct-use threading insert for LT11 style internal threading toolholders accepting inserts with a 1/4-inch inscribed circle and 11NR insert style designation.

Installation Notes

Threading inserts should be installed by a qualified machinist or toolroom technician with the machine spindle fully stopped and the toolholder secured in the turret. Torx or hex keys appropriate to the clamping screw size should be used to seat the insert flush against the toolholder pocket. Inspect the pocket for chips or debris before seating the insert to avoid rocking or improper contact. Always verify thread form and pitch against the workpiece drawing before initiating a threading pass.
