Sandvik Coromant 5753711 Threading Insert Carbide Tialn

Product Description

The SANDVIK COROMANT 5753711 is a carbide threading insert in the Top Lok series, designed for cutting both internal and external threads on CNC lathes and threading machines. The insert carries a TiAlN finish applied via PVD coating, which provides thermal resistance and extended tool life in demanding cutting conditions. It covers an internal and external pitch range of 1.25 to 6.25 mm (4 to 20 TPI) and is ground to a 60-degree V thread standard. The ISO designation is TLTP-4R 1125, indicating a right-hand insert with a size 4 body. This insert is installed and indexed by machinists and CNC tooling technicians performing precision threading operations.

This insert is suited for threading applications in job shops, production turning cells, and maintenance machining environments. It handles both inch-series and metric thread forms within its pitch range, making it a versatile choice for shops running mixed work. The right-hand configuration fits standard Top Lok toolholders. It is appropriate for threading steel, alloy, and similar machinable materials where a PVD TiAlN-coated carbide grade performs reliably.

Key Features

• Carbide substrate with PVD TiAlN coating for extended wear resistance
• Covers 1.25 to 6.25 mm and 4 to 20 TPI pitch range in a single insert
• 60-degree V thread form for both internal and external threading
• Right-hand cutting orientation; ISO code TLTP-4R 1125
• Corner radius of 0.10 mm (0.0040 inches) for precise thread root geometry
• Top Lok series interface for secure, repeatable seating in compatible toolholders

Compatibility

Designed for use with Top Lok series threading toolholders that accept size 4 TLTP-style inserts. Consult the toolholder documentation to confirm seat geometry and clamping compatibility before installation.

Installation Notes

Threading inserts of this type are indexed or replaced by machinists with the machine powered off and the spindle fully stopped. Use the appropriate Top Lok torx or hex key to the toolholder manufacturer's specified seating procedure when clamping the insert. Inspect the insert pocket and clamping screw for wear or debris before seating a new insert. Handle carbide inserts carefully to avoid chipping the cutting edge prior to use.
