Kennametal 1192237 Indexable Thread Mill 0.79in Internal External

Product Description

The KENNAMETAL 1192237 is an indexable thread mill designed for both internal and external threading operations on CNC machining centers. It accepts a single STN16-style insert held by screw, with a cutting diameter of 0.79 inches and a neck diameter of 0.65 inches. The tool has an overall length of 3.75 inches and supports a maximum hole depth of 1.68 inches. Through-coolant capability is built in, helping to evacuate chips and manage heat during threading cycles. This tool is intended for machinists and tooling specialists working in production or job-shop environments where thread milling is preferred over tapping.

This thread mill suits applications requiring precise thread generation in both through and blind holes across internal and external configurations. The single-flute design with a 3/8-inch insert inscribed circle and Toolholder Style K079 makes it appropriate for threading operations where controlled engagement and repeatability are critical. It is used in aerospace, automotive, die-and-mold, and general precision machining environments where thread quality and tool life consistency are priorities.

Key Features

• Cutting diameter of 0.79 inches for consistent thread profile engagement
• Maximum hole depth capacity of 1.68 inches
• Accepts one STN16 insert with 3/8-inch inscribed circle, secured by screw clamp
• Through-coolant design for chip evacuation and thermal management
• Compatible with internal and external thread milling in a single tool
• Neck diameter of 0.65 inches reduces interference in tight-bore applications

Compatibility

Designed for use with STN16 insert style and Toolholder Style K079. Accepts a single threading insert with a 3/8-inch inscribed circle. Verify spindle interface and insert availability before ordering for your specific machine setup.

Installation Notes

Thread mill installation and setup should be performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully stopped and the tool changer is in a safe state before mounting or removing the holder. Confirm insert seating and screw torque per the insert manufacturer's guidelines before running. Program thread milling cycles using helical interpolation appropriate to the thread specification being cut.
