Sandvik Coromant 5907045 Laydown Threading Insert 12-24 Tpi

Product Description

The SANDVIK COROMANT 5907045 is a solid carbide laydown threading insert designed for internal right-hand 60-degree V thread cutting across a range of thread pitches. Part of the CoroThread 266 series, this insert carries a PVD-applied TiCrAlN/TiN coating that supports wear resistance and tool life in demanding threading operations. It covers 12 to 24 TPI with a pitch range of 1.00 to 2.00 mm, making it suitable for a broad span of standard unified and metric-equivalent thread applications. The inscribed circle measures 3/8 inches and the insert thickness is 5/32 inches. Installation is performed by machinists and toolroom technicians using compatible CoroThread 266 toolholders.

This insert is suited for internal threading operations in ferrous and non-ferrous materials where a 60-degree V thread form is required. The right-hand cutting geometry and C chipbreaker designation make it appropriate for through-hole and blind-hole applications in production turning and general machining environments. The 266RL-16VM01C001M designation within the CoroThread 266 series identifies the insert geometry, size code 16, and grade 1135 substrate. Grade 1135 is a PVD-coated carbide grade commonly applied in threading of steel and stainless steel at moderate to high cutting speeds.

Key Features

• Solid carbide substrate with PVD TiCrAlN/TiN coating for extended tool life in threading operations
• Right-hand internal cutting geometry for standard unified and metric 60-degree V threads
• Thread range of 12 to 24 TPI (1.00 to 2.00 mm pitch) covers a wide range of common fastener threads
• C chipbreaker for controlled chip formation in internal threading
• Inscribed circle of 3/8 inches (9.53 mm) and thickness of 5/32 inches (3.97 mm) in CoroThread 266 laydown format
• Corner radius of 0.0024 inches (0.06 mm) for sharp, accurate thread profile engagement

Compatibility

Designed for use with compatible SANDVIK COROMANT CoroThread 266 series toolholders accepting size code 16 laydown threading inserts with the corresponding insert style designation.

Installation Notes

This insert is seated and secured by a machinist or toolroom technician in a CoroThread 266-compatible toolholder; confirm the toolholder insert pocket and clamping screw are in serviceable condition before seating the insert. Ensure the machine spindle is fully stopped and the turret or toolpost is de-energized before changing inserts. Use the manufacturer-specified torque tool for the clamping screw to avoid insert fracture or improper seating. Do not use damaged or chipped inserts, as solid carbide threading inserts are brittle and should be handled carefully to prevent edge damage before installation.
