Sandvik Coromant 5735678 Threading Insert Carbide Corocut Mb

Product Description

The SANDVIK COROMANT 5735678 is a left-hand, internal threading insert in the CoroCut MB series, designed for precision thread-cutting operations on CNC lathes and turning centers. Built from carbide with a PVD-applied TiAlN/TiN finish, it delivers consistent wear resistance and thermal stability during interrupted and continuous threading passes. The insert follows a partial profile 60-degree thread standard with an internal pitch of 0.50 mm, making it suited for fine-pitch internal threading in ferrous and non-ferrous materials. Grade 1025 carbide provides a balance of toughness and edge retention for medium-duty threading applications. Installation and handling require standard insert tooling for the MB07 seat size.

This insert is intended for internal threading applications in precision machining environments, including CNC turning and Swiss-type machines where the CoroCut MB system is in use. The left-hand cutting geometry suits specific spindle direction and bore orientation requirements common in production machining. It is appropriate for shops running fine-pitch metric threading operations where consistent thread form and surface finish are required on internal features.

Key Features

• Carbide substrate with PVD TiAlN/TiN coating for wear resistance and thermal protection
• Partial profile 60-degree thread form for internal metric threading at 0.50 mm pitch
• Left-hand cutting geometry for specific bore and spindle orientation setups
• Grade 1025 carbide balances toughness with edge retention in medium-duty applications
• CoroCut MB series insert style, size 7, for use in compatible MB07 toolholders
• Compact insert dimensions suited for tight-bore and small-diameter threading operations

Compatibility

Designed for use with compatible MB07-series toolholders in the SANDVIK COROMANT CoroCut MB system. Confirm seat geometry and clamping compatibility with the specific toolholder before installation.

Installation Notes

This insert should be installed and replaced by a qualified machinist or CNC tooling technician. Power down and lock out the machine before changing inserts. Use the correct torque wrench and insert key specified for the MB07 clamping system to avoid seat damage. Inspect the pocket and clamping screw for wear before seating a new insert.
