Sandvik Coromant 5907010 Threading Insert Npt 14 Tpi

Product Description

The SANDVIK COROMANT 5907010 is a laydown threading insert from the CoroThread 266 series, designed for cutting right-hand internal NPT threads. Built from solid carbide with a PVD-applied TiCrAlN/TiN finish, this insert delivers consistent thread form and extended tool life in demanding threading operations. It is engineered for a 14 threads per inch (TPI) pitch with a 60-degree included angle, a 3/8-inch (9.53 mm) inscribed circle, and a thickness of 5/32 inch (3.97 mm). Licensed machinists, toolroom technicians, and CNC operators working in metalworking and pipe fabrication environments are the primary installers of this insert.

This insert is suited for internal NPT thread applications in production and job-shop environments where pipe fitting and fluid-connection threads must meet tight dimensional standards. The single-tooth-per-side geometry and C chipbreaker designation make it appropriate for controlled, repeatable threading passes on lathes and turning centers. It is a strong fit for shops producing threaded pipe connectors, fittings, and fluid-system components in steel and other machinable metals where a PVD-coated solid carbide grade is specified.

Key Features

• Solid carbide substrate with PVD TiCrAlN/TiN coating for wear resistance and heat stability
• Right-hand internal NPT thread form at 14 TPI with a 60-degree included angle
• CoroThread 266 series insert style with C chipbreaker for controlled chip formation
• 3/8-inch inscribed circle and 0.1732-inch hole diameter for secure seating in compatible toolholders
• Manufacturer grade 1135 matched to PVD coating process for optimal cutting performance
• Single tooth per side design for precise, repeatable thread profiles

Compatibility

Designed for use in SANDVIK COROMANT CoroThread 266 series toolholders that accept insert style 266RL-16NT01C140M. Confirm toolholder and pocket geometry match the 16 insert size code before installation.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician following the machine tool manufacturer's insert-seating procedures. Power down and lock out the machine before changing inserts. Use the correct torx or insert-clamping wrench to seat the insert fully and evenly in the pocket without over-torquing the clamping screw. Inspect the toolholder pocket for debris or wear before seating a new insert to ensure proper contact and repeatability.
