Sandvik Coromant 5765635 Indexable Drill Insert 880 Square

Product Description

The SANDVIK COROMANT 5765635 is a solid carbide indexable drill insert designed for use in compatible 880-series indexable drilling systems. Built to the 880 insert style with a square shape and GR chipbreaker geometry, this insert is PVD-coated with TiAlN for improved heat resistance and extended tool life in demanding drilling operations. It measures 0.7047 inches inscribed circle diameter (17.90 mm), with a thickness of 0.2165 inches and a corner radius of 0.0315 inches (0.80 mm). Installation is performed by CNC machinists and toolroom technicians working in metalcutting environments where precise hole tolerances and consistent chip evacuation are required.

This insert is suited for use in the 880-series indexable drill bodies in industrial metalcutting applications including steel, alloy steel, and similar materials. The TiAlN PVD coating supports higher cutting speeds and provides oxidation resistance at elevated temperatures. The GR chipbreaker promotes reliable chip control during through-hole and blind-hole drilling operations. It is sized to the 09C insert seat designation with a hole diameter of 0.1850 inches (4.70 mm) for secure mechanical clamping in the drill body.

Key Features

• 880 insert style with square shape and GR chipbreaker geometry for controlled chip evacuation
• Solid carbide substrate with TiAlN PVD coating for heat and wear resistance
• Inscribed circle of 0.7047 inches (17.90 mm) and 09C insert size designation
• Corner radius of 0.0315 inches (0.80 mm) for edge strength in drilling applications
• Mounting hole diameter of 0.1850 inches (4.70 mm) for positive mechanical clamping
• Thickness of 0.2165 inches for dimensional consistency across compatible 880-series holders

Compatibility

Designed as a replacement insert for compatible 880-series indexable drill bodies accepting 09C seat size, square-style inserts with a 0.7047-inch inscribed circle and 0.1850-inch mounting hole. Verify seat designation and clamping geometry against the drill body specification before installation.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Power down and lock out the machine spindle before seating or removing inserts. Use the appropriate torx or hex key torque driver as specified by the drill body manufacturer for the clamping screw. Inspect the insert pocket for debris or wear before seating a new insert to ensure proper seating and runout.
