Sandvik Coromant 6633722 Indexable Drill Insert 880

Product Description

The SANDVIK COROMANT 6633722 is a solid carbide indexable drill insert designed for use in indexable drilling operations requiring precise, repeatable cutting performance. This insert carries the 880 style designation with a GM chipbreaker geometry and is coated via CVD process with a TiCN/Al2O3/TiN multilayer stack. The square insert shape features a 0.498-inch (12.65 mm) inscribed circle, a thickness of 0.1575 inches (4.00 mm), and a corner radius of 0.0236 inches (0.60 mm). Manufacturer grade 4334 indicates a wear-resistant substrate suited for demanding drilling applications in ferrous and other machinable materials. Installation and changeout are performed by machinists and tool-crib technicians in production machining environments.

This insert is intended for use in 880-series indexable drill bodies where a square insert seat is required. The GM chipbreaker geometry is optimized for chip control in through-hole and blind-hole drilling operations. Right-hand cutting direction means it is compatible with standard spindle rotation on CNC machining centers, turning centers with live tooling, and manual drill presses configured for conventional drilling. Insert size designation 070406 allows cross-referencing against toolholder seat specifications to confirm fit before installation.

Key Features

• Solid carbide substrate with manufacturer grade 4334 for wear resistance in demanding drilling applications
• CVD-applied TiCN/Al2O3/TiN multilayer coating for thermal and abrasion resistance
• GM chipbreaker geometry for effective chip control in through-hole and blind-hole drilling
• Square insert shape with 0.498-inch inscribed circle and 0.60 mm corner radius
• Right-hand cutting direction for use with standard spindle rotation
• Insert size 070406 for straightforward seat-size verification

Compatibility

Designed as an OEM-style replacement insert for 880-series indexable drill bodies requiring a square-seat insert with a 12.65 mm inscribed circle. Confirm toolholder seat geometry and insert size designation 070406 against the drill body specification before ordering.

Installation Notes

Insert changeout should be performed by qualified machinists or tooling technicians with the machine spindle fully stopped and locked out per applicable lockout/tagout procedures. Use the correct Torx or hex key torque driver as specified by the drill body manufacturer for the clamping screw to avoid seat damage or insert cracking. Inspect the insert pocket and clamping screw for wear or debris before seating the new insert. Never force an insert into a damaged or undersized pocket.
