Sandvik Coromant 5735938 Carbide Threading Insert Un 24 Tpi

Product Description

The SANDVIK COROMANT 5735938 is a carbide threading insert designed for internal UN thread cutting applications. It belongs to the CoroCut MB series and carries the ISO code MB07TH240UN10R1025. The insert features a TiAlN/TiN finish applied by PVD coating process, which supports heat resistance and edge wear performance in threading operations. At insert size 7 with a 60-degree included angle and a 24 TPI internal pitch, this right-hand insert is suited for precision thread production on CNC lathes and turning centers. Machinists and tool-and-die professionals are the primary users of this type of tooling.

This threading insert is used in internal UN thread turning operations on CNC and manual lathes. The CoroCut MB series is engineered for small-part threading and parting applications where close tolerances and surface finish quality are critical. Typical installation scenarios include threading bores in aerospace, medical, and general machining workpieces. The right-hand configuration and 24 TPI pitch make it appropriate for standard UN fastener thread profiles in production and job-shop environments.

Key Features

• Carbide substrate with TiAlN/TiN PVD coating for wear resistance in threading operations
• 24 TPI internal pitch for UN thread standard applications
• 60-degree included angle matched to UN thread form geometry
• Right-hand cut orientation for standard lathe threading setups
• CoroCut MB series insert size 7 for small-bore and precision threading
• ISO code MB07TH240UN10R1025 for exact cross-reference identification

Compatibility

Designed as an OEM-style replacement or direct-use insert for CoroCut MB series toolholders accepting size 7 threading inserts in UN internal thread configurations.

Installation Notes

Threading inserts of this type are installed and replaced by machinists or toolroom technicians on CNC or manual turning equipment. Power down and lock out the machine spindle before indexing or replacing inserts. Use the correct torque wrench and insert clamp screw as specified by the toolholder manufacturer — do not overtighten by hand. Inspect the seating pocket for chips or debris before seating a new insert to ensure proper support and thread accuracy.
