Seco 00075891 Threading Insert 26NR CP300 Solid Carbide

Product Description

The SECO 00075891 is a laydown threading insert designed for right-hand internal trapezoidal thread cutting. Built from solid carbide and finished with a PVD-applied TiAlN/TiN coating, this insert delivers wear resistance and heat dissipation suited to demanding threading operations. It carries the CP300 manufacturer grade and features a 15.88 mm inscribed circle with a thickness of 7.88 mm (0.3102 inches). Machinists and CNC operators in production and job-shop environments rely on this insert for consistent thread form accuracy on internal trapezoidal profiles. The 26NR style designation governs geometry and seating for compatible toolholders.

This insert is applied to internal trapezoidal threading operations at a pitch of 10.00 mm. Trapezoidal thread forms are common in lead screws, linear actuators, power transmission components, and industrial machinery. The right-hand cutting orientation suits the majority of standard threading cycles. This insert is sold individually with a minimum order quantity of two units, making it appropriate for tooling stock replenishment or initial setup in high-volume threading applications across metalworking, maintenance, and precision machining operations.

Key Features

• Solid carbide construction for rigidity and extended tool life in threading applications
• PVD TiAlN/TiN coating provides thermal resistance and reduced flank wear
• CP300 grade optimized for internal threading performance
• 26NR insert style with 15.88 mm inscribed circle for precise toolholder seating
• Right-hand cutting geometry for standard internal trapezoidal thread cycles
• 10.00 mm pitch matches common lead screw and power transmission thread standards

Compatibility

Designed for use in toolholders accepting the 26NR laydown insert style for internal trapezoidal threading at 10.00 mm pitch. Confirm toolholder designation and insert pocket geometry before installation.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Power down and lock out the machine before changing inserts. Use the correct torque wrench and insert screw to seat the insert fully against the pocket without over-torquing, which can fracture solid carbide. Verify thread form and pitch against part drawing requirements before running production cuts.
