Sandvik Coromant 6012452 Threading Insert 8-16 Tpi Solid Carbide

Product Description

The SANDVIK COROMANT 6012452 is a solid carbide laydown threading insert from the CoroThread 266 series, designed for internal right-hand 60-degree V-thread cutting applications. The insert carries manufacturer grade 7015 with a PVD-applied TiN coating for edge wear resistance and extended tool life in demanding threading operations. It covers a thread range of 8-16 TPI (1.50-3.00 mm pitch), has an inscribed circle of 3/8 inches (9.53 mm), and measures 5/32 inches (3.97 mm) thick. Licensed machinists and CNC lathe operators install this insert into compatible CoroThread 266 toolholders for precision internal thread production on lathes and machining centers.

This insert is suited for internal threading operations on CNC turning centers and lathes in industrial machining environments. Its 60-degree included angle covers the most common unified and metric V-thread profiles in the 8-16 TPI range. The chipbreaker designation A and a corner radius of 0.0035 inches (0.09 mm) make it appropriate for fine-pitch threading where edge geometry and chip control are critical. It is typically used in production shops, job shops, and maintenance machining where consistent thread form and repeatable insert indexing are required.

Key Features

• Solid carbide substrate with PVD TiN coating for wear resistance and edge integrity
• Covers 8-16 TPI (1.50-3.00 mm pitch) for versatile internal threading across common V-thread profiles
• Right-hand internal 60-degree V-thread geometry matches unified and metric thread standards
• CoroThread 266 series insert with A chipbreaker for controlled chip evacuation
• Corner radius of 0.0035 inches (0.09 mm) supports precise thread root form
• Mounting hole diameter of 0.1732 inches (4.40 mm) for secure clamping in compatible toolholders

Compatibility

Designed for use in SANDVIK COROMANT CoroThread 266 series toolholders that accept 16-size right-hand internal threading inserts. Verify toolholder compatibility using the manufacturer catalog number 266RL-16VM01A002EE 7015 when selecting the appropriate holder.

Installation Notes

Insert installation and indexing should be performed by a qualified machinist or CNC tooling technician. Power down and lock out the machine spindle before removing or seating any cutting insert. Use the appropriate Torx or clamping key specified for the CoroThread 266 toolholder to seat the insert securely without overtightening. Inspect the insert pocket for debris or damage before each installation to ensure correct seating and thread form accuracy.
