Sandvik Coromant 6633709 Indexable Drill Insert Grade 4334

Product Description

The SANDVIK COROMANT 6633709 is a solid carbide indexable drill insert engineered for use in compatible 880-series indexable drilling systems. Built to grade 4334 with a multilayer TiCN/Al2O3/TiN coating applied via the CWD process, this insert delivers wear resistance and thermal stability under demanding cutting conditions. The square insert shape features a 6.00 mm (0.2362 inches) inscribed circle, a 0.60 mm (0.0236 inches) corner radius, and a GR chipbreaker geometry. It is sized at insert size 03P with a thickness of 0.1024 inches. Right-hand cutting direction is standard. Installation is handled by machinists and tooling technicians in production machining environments.

This insert is suited for indexable drilling operations in both shop floor production and job-shop environments. The GR chipbreaker geometry promotes chip control during through-hole and blind-hole drilling in a range of workpiece materials. The 2.50 mm (0.0984 inches) mounting hole accommodates standard clamping hardware for the corresponding toolholder. Typical applications include CNC machining centers and turning centers equipped with live tooling. The minimum order quantity for this insert is 10 pieces.

Key Features

• Multilayer TiCN/Al2O3/TiN coating via CWD process for extended tool life
• GR chipbreaker geometry designed for controlled chip formation during drilling
• Square insert shape, insert size 03P, with 6.00 mm inscribed circle
• 0.60 mm corner radius reduces stress concentration at the cutting edge
• Right-hand cutting direction, compatible with standard 880-series toolholder configurations

Compatibility

Designed as an OEM-style replacement insert for SANDVIK COROMANT 880-series indexable drill toolholders requiring a square, 03P-size solid carbide insert with GR chipbreaker geometry and a 2.50 mm mounting hole.

Installation Notes

Installation is performed by qualified machinists or tooling technicians. Power down and lock out the machine spindle before seating or removing inserts. Use the correct torx or hex key specified by the toolholder manufacturer when tightening the clamp screw; do not overtighten, as this can crack the insert or damage the pocket. Inspect the insert pocket and seating surfaces for chips or debris before installing a new insert.
