Sandvik Coromant 5954570 Threading Insert Carbide Tialn

Product Description

The SANDVIK COROMANT 5954570 is a carbide threading insert in the Top Lok series, designed for cutting internal and external threads on CNC lathes and turning centers. Carrying the ISO code TLTF-3L 1125, it features a TiAlN finish applied via PVD coating and a left-hand cutting orientation. The 1125 grade carbide substrate combined with TiAlN coating supports threading operations across a pitch range of 0.60 to 2.50 mm (9 to 44 TPI) on a 60-degree V thread form. This insert is installed by machinists and CNC turning specialists in job shops, production environments, and maintenance machining applications.

This insert handles both internal and external threading on a 60-degree V thread standard, covering a wide pitch range suitable for metric and unified thread forms. The left-hand configuration makes it appropriate for reverse-thread or left-hand-thread applications where standard right-hand inserts cannot be used. It seats in Top Lok-style toolholders designed for this insert series and size. Typical applications include threading steel, stainless, and similar machinable alloys in production turning setups.

Key Features

• Carbide substrate with TiAlN PVD finish for wear resistance in threading operations
• Left-hand cutting orientation for reverse-thread and left-hand-thread applications
• Covers 0.60 to 2.50 mm and 9 to 44 TPI pitch range on internal and external threads
• 60-degree included angle for standard V-form thread profiles
• Insert size 3 with a tip-to-top height of 0.3440 inches (8.74 mm) and cutting tip width of 0.1950 inches (4.95 mm)
• Corner radius of 0.0030 inches (0.08 mm) for precise thread root geometry

Compatibility

Designed for use with Top Lok series threading toolholders that accept a size 3 TLTF-style insert. Consult the toolholder manufacturer specification to confirm seat geometry and clamping compatibility before installation.

Installation Notes

Threading inserts should be installed by qualified machinists or CNC turning technicians. Power down and lock out the machine spindle before seating or replacing any insert. Use the correct Top Lok clamping hardware and verify the insert is fully seated and clamped before running. Inspect the insert seat and clamping screw for wear or debris prior to installation to ensure secure engagement.
