Sandvik Coromant 6633715 Indexable Drill Insert 880GT

Product Description

The SANDVIK COROMANT 6633715 is a solid carbide indexable drill insert designed for use in compatible indexable drill bodies requiring an 880-style square insert. Carrying grade 4334 with a multilayer TiCN/Al2O3/TiN coating applied via the CWD process, this insert is engineered for high-wear resistance and thermal stability in demanding drilling operations. The inscribed circle measures 8.90 mm (0.3504 inches), thickness is 0.1181 inches, and the corner radius is 0.80 mm (0.0315 inches). It features the GT chipbreaker geometry and is ground for right-hand cutting direction. Installation is performed by machinists and tooling technicians working in metal-cutting environments.

This insert is intended for use in CNC machining centers, lathes with live tooling, and dedicated drilling machines where the 880-style indexable drill system is specified. The square insert shape and size designation 05P make it a peripheral or central seat replacement depending on the drill body configuration. Typical applications include hole-making in ferrous and non-ferrous workpieces at moderate to high cutting speeds where coating durability and edge consistency are required.

Key Features

• Solid carbide substrate with multilayer TiCN/Al2O3/TiN coating for extended tool life
• CWD coating process for uniform layer adhesion and thermal resistance
• GT chipbreaker geometry for controlled chip evacuation in drilling operations
• 0.80 mm corner radius reduces edge stress and supports surface finish consistency
• Right-hand cutting direction, square shape, insert size 05P
• Mounting hole diameter of 3.20 mm (0.1260 inches) for secure clamping in compatible drill bodies

Compatibility

Designed as an OEM-style replacement insert for indexable drill bodies accepting 880-style square inserts with an 05P size designation and a 3.20 mm mounting hole.

Installation Notes

Insert replacement should be performed by a qualified machinist or tooling technician with the machine fully stopped and locked out per applicable machine safety procedures. Use the correct torx or hex key to the drill body manufacturer's clamping specification when seating the insert. Inspect the insert pocket and clamping screw for wear or debris before installing a new insert. Do not exceed the cutting parameters specified for grade 4334 and the 880 drill body in use.
