Iscar 3199254 Milling Tip Threaded Extension T12

Product Description

The ISCAR 3199254 is a milling tip threaded extension designed for use in modular tooling systems where reach beyond the standard holder length is required. It features a T12 thread connection on both the tip and shank ends, allowing it to integrate seamlessly into T12-compatible tooling chains. The extension measures 1.5 inches in length with a maximum diameter of 0.72 inches. It belongs to the Multimaster series, a modular milling platform that allows quick interchange of cutting heads and extensions without removing the entire assembly from the spindle. Machinists and tooling technicians use this component to extend cutting reach in tight-clearance or deep-pocket milling applications.

This extension is suited for CNC milling operations in job shop, production, and tool room environments. The T12 modular interface supports a range of Multimaster cutting heads, making this extension applicable across multiple materials and milling strategies. Its compact diameter of 0.72 inches allows access to narrow workpiece features while maintaining rigidity appropriate for the extension length. It is typically installed by tooling technicians or CNC machinists as part of a configured tooling assembly.

Key Features

• T12 thread connection on both tip and shank ends for full compatibility within the Multimaster modular system
• 1.5 inch extension length provides added reach for deep-pocket or restricted-access milling
• 0.72 inch maximum diameter maintains clearance in tight workpiece features
• Multimaster series interface enables rapid head changes without full toolholder removal
• Lightweight construction at 0.01 pounds minimizes added mass in the tooling stack

Compatibility

Designed for use with T12 Multimaster series tooling assemblies. Compatible cutting heads and shanks must use the T12 modular thread interface. Specific compatible heads and holders were not identified in the available product data.

Installation Notes

Installation is performed by tooling technicians or CNC machinists during tool assembly. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before handling any tooling components. Thread the extension onto the T12 shank connection hand-tight before using the appropriate torque tool specified by the tooling system manufacturer. Inspect all threaded interfaces for debris or damage before assembly to maintain concentricity and avoid premature wear.
