Sandvik Coromant 6633704 Indexable Drill Insert 880LM

Product Description

The SANDVIK COROMANT 6633704 is a solid carbide indexable drill insert designed for use with compatible 880-series indexable drills. Manufactured to the 4334 grade with a CVD-applied TiCN/Al2O3/TiN multilayer coating, this insert delivers wear resistance and thermal stability during high-feed drilling operations in steel and cast materials. The square insert profile features an LM chipbreaker geometry suited for light to medium cutting conditions. Key dimensions include a 5.10 mm (0.2008 inches) inscribed circle, 0.0945 inches thickness, and a 0.50 mm (0.0197 inches) corner radius. Installation is performed by licensed machinists or tooling technicians on CNC or manual drill platforms.

This insert is intended for use in 880-style indexable drill bodies requiring square inserts with the LM chipbreaker and 4334 carbide grade. Typical applications include through-hole and blind-hole drilling in ferrous and alloyed workpiece materials in general machining, job-shop, and production environments. Right-hand cutting direction suits standard spindle rotation. The 2.20 mm (0.0866 inches) mounting hole diameter must align with the insert pocket and clamping screw of the host drill body.

Key Features

• Solid carbide substrate with CVD multilayer TiCN/Al2O3/TiN coating for extended tool life
• 4334 manufacturer grade formulated for wear resistance in steel and cast iron drilling
• LM chipbreaker geometry optimized for light to medium chip formation and evacuation
• Square insert shape with 0.50 mm corner radius reduces edge stress at entry and exit
• Right-hand cutting direction for use with standard clockwise spindle rotation
• Insert size 020205 for precise pocket seating in compatible 880-series drill bodies

Compatibility

Designed as an OEM-style replacement insert for 880-series indexable drill bodies requiring a square, LM-chipbreaker insert in the 4334 grade with a 5.10 mm inscribed circle and 2.20 mm mounting hole. Confirm pocket dimensions and clamping screw size against the host drill body specification before ordering.

Installation Notes

Insert seating and clamping should be performed by a qualified machinist or tooling technician with the spindle locked and machine power isolated before any insert change. Use the correct Torx or hex key as specified by the drill body manufacturer for the clamping screw. Inspect the insert pocket for debris, damage, or wear before seating the new insert. Never force an insert into a pocket; improper seating can cause insert fracture or workpiece damage during operation.
