Ingersoll Cutting Tools 6104898 Indexable Drill Insert

Product Description

The INGERSOLL CUTTING TOOLS 6104898 is a square indexable drill insert in the SOMT-SK series, designed for use in QR-compatible indexable drill bodies. Manufactured from solid carbide and finished with a PVD-applied TiCN coating, this insert is built for cutting steel, stainless steel, superalloys, and titanium. It carries manufacturer grade IN1030 and features a positive rake geometry that reduces cutting forces during hole-making operations. With four usable cutting edges, the insert delivers extended tool life per unit. The inscribed circle measures 0.362 inches, thickness is 0.166 inches, and the corner radius is 0.031 inches. Machinists and toolroom professionals in metalworking and aerospace supply environments are the primary installers of this insert.

This insert is suited for drilling operations in both production machining and job-shop environments where steel, stainless steel, and high-temp alloys are common workpiece materials. The SOMT09T308SK geometry and SK chipbreaker are optimized for controlled chip evacuation in these material groups. The insert mounts in QR-style indexable drill bodies and is identified by insert size code 09T308. Applications span general metalcutting, aerospace component work, and structural fabrication where consistent hole geometry and surface finish are required.

Key Features

• Positive rake geometry reduces cutting forces and heat generation
• SK chipbreaker promotes controlled chip formation and evacuation
• Square SOMT09T308SK form with 90-degree included angle for consistent hole entry
• Compatible with QR-style indexable drill bodies

Compatibility

Designed for use in QR-style compatible indexable drill bodies. ANSI and ISO designation SOMT09T308SK. Insert size code 09T308.

Installation Notes

Insert seating and torquing should be performed by a qualified machinist or toolroom technician following the drill body manufacturer's clamping specifications. Power down and lock out the machine spindle before indexing or replacing inserts. Inspect the insert pocket and clamping screw for wear or damage before seating a new insert. Do not exceed the recommended cutting parameters published by the drill body manufacturer for this insert geometry.
