Kennametal 1817512 Threading Insert 4 Tpi Api Carbide

Product Description

The KENNAMETAL 1817512 is a solid carbide laydown threading insert designed for external API Rotary Shoulder Connections threading applications. It carries the manufacturer grade KC5010 and features a Physical Vapor Deposition (PVD) applied TiAlN coating, which provides thermal resistance and wear protection during demanding threading operations. The insert runs at 4 threads per inch (TPI) and has a 1/2 inch inscribed circle diameter. At 0.1880 inches thick, it seats in standard LT22ER-style toolholders. This insert is used by machinists and turning specialists working in oil and gas, energy, or heavy-equipment sectors where API-standard threaded connections are required.

This insert is suited for precision external threading of API Rotary Shoulder Connections on components such as drill collars, subs, and other downhole tubular fittings. The right-hand cutting orientation matches standard lathe rotation for external thread profiles. The KC5010 carbide grade with TiAlN PVD coating is matched to threading applications involving alloy steels and high-strength materials common in oilfield manufacturing environments. It is sold individually with a minimum order quantity of 10 units.

Key Features

• Solid carbide construction in KC5010 grade for wear resistance in demanding threading operations
• TiAlN coating applied via PVD process for thermal protection and extended tool life
• Right-hand external thread geometry at 4 TPI for API Rotary Shoulder Connections profiles
• 1/2 inch inscribed circle with 0.1921 inch hole diameter for secure clamping in compatible toolholders
• Insert style 22ER for use in standard LT22ER-designated toolholding systems
• Thickness of 0.1880 inches (4.64mm) for consistent seating and repeatable thread form

Compatibility

Designed for use in LT22ER-style laydown threading toolholders. Specific compatible model or system data was not provided in the available product information; verify toolholder compatibility using the 22ER insert style designation and inscribed circle size before ordering.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician following the toolholder manufacturer's clamping specifications. Power down the machine and lock out the spindle before changing inserts. Ensure the insert pocket is clean and free of chips or debris before seating the insert. Handle carbide inserts carefully to avoid chipping the cutting edge prior to use.
