Sandvik Coromant 6765584 Threading Insert Metric External

Product Description

The SANDVIK COROMANT 6765584 is a solid carbide on-edge threading insert engineered for external metric threading operations on CNC lathes and turning centers. Manufactured to MATR insert style with a size code 3 designation, this insert features an AlTiN coating applied via PVD process, delivering strong oxidation resistance and extended tool life at elevated cutting temperatures. The insert measures 0.25 inches in length, 0.25 inches in width, and 0.1250 inches in thickness, with a 0.1890-inch hole diameter for secure clamping. Machining professionals and CNC operators use this insert for high-precision thread-turning applications where dimensional accuracy and surface finish consistency are critical.

This insert is designed for right-hand cutting direction and conforms to the metric thread standard, making it suitable for producing external metric threads on steel, stainless steel, and similar workpiece materials in both job shop and production environments. The solid carbide substrate paired with the PVD AlTiN coating supports higher cutting speeds and improved wear resistance compared to uncoated grades. It carries manufacturer grade designation 1105, indicating its intended cutting material and application range within the SANDVIK COROMANT grade system. Installation is performed by CNC machinists and tool-room technicians in precision machining environments.

Key Features

• Solid carbide substrate with PVD AlTiN coating for heat and wear resistance
• MATR insert style, size code 3, for on-edge threading geometry
• Right-hand cutting direction for external metric thread profiles
• 0.1250-inch insert thickness and 0.1890-inch hole diameter for positive seating
• Corner radius of 0.0043 inch for accurate thread form generation
• Manufacturer grade 1105 optimized for threading performance

Compatibility

Designed as an OEM-style on-edge threading insert compatible with toolholders and cartridges accepting MATR-style size code 3 inserts for external metric threading applications.

Installation Notes

Installation should be performed by a qualified CNC machinist or toolroom technician with the machine spindle fully stopped and all axis movement locked out per facility lockout/tagout procedures. Use the correct torx or hex key specified by the toolholder manufacturer to achieve proper clamping torque — do not overtighten the clamping screw as this may fracture the carbide insert. Inspect the insert seat and clamping components for debris or wear before seating a new insert. Handle solid carbide inserts carefully to avoid chipping the cutting edges prior to use.
