Ingersoll Cutting Tools 3031431 Face Mill 2 Inch KJ5G

Product Description

The INGERSOLL CUTTING TOOLS 3031431 is a 2-inch indexable square-shoulder face mill built around the KJ5G cutter style. It accepts 5 indexable inserts held by screw-clamp retention and runs a positive rake geometry for reduced cutting forces. The arbor hole measures 0.75 inches in diameter with a 5/16-inch keyway for secure spindle mounting. Right-hand cutting direction and a 90-degree lead angle make this tool suited to true square-shoulder work. Maximum depth of cut is 0.41 inches, and close pitch insert spacing supports stable material removal across facing, ramping, and shouldering operations. Compatible insert size code is 1005, with full insert compatibility listed as THES1005.

This face mill is intended for general-purpose machining on a universal range of workpiece materials, making it a practical choice for job shops and production environments alike. The KJ5G series is designed for three primary operations: facing flat surfaces, ramping into a workpiece at angles up to 1.5 degrees, and generating true 90-degree shoulders. Coolant-through capability allows cutting fluid to be delivered directly to the cutting zone, which is particularly useful in deep or continuous facing passes. A licensed machinist or tooling technician typically sets up and qualifies this cutter on CNC vertical or horizontal machining centers.

Key Features

• 2-inch cutting diameter with 90-degree lead angle for true square-shoulder capability
• 5-insert close-pitch configuration for stable, productive material removal
• Positive rake geometry reduces cutting forces and heat generation
• Coolant-through design delivers fluid directly to the cutting zone
• Maximum ramping angle of 1.5 degrees supports plunge and ramp-entry strategies
• Screw-clamp insert retention for repeatable insert indexing and secure holding

Compatibility

Designed for use with THES1005 indexable inserts (size code 1005). Mounts via a 0.75-inch arbor hole with a 5/16-inch keyway. No additional model-specific compatibility data was provided in the product information.

Installation Notes

A qualified machinist or CNC tooling technician should mount and qualify this cutter. Power down and lock out the spindle drive before installing or indexing inserts. Verify arbor and keyway fit before torquing the arbor bolt, and confirm insert seating and screw engagement before the first cut. Follow the machine tool manufacturer guidelines and applicable shop safety procedures when setting cutting parameters.
