Allied Machine TM18150 Thread Mill M18x1.50 4 Flute Carbide

Product Description

The ALLIED MACHINE AND ENGINEERING TM18150 is a solid carbide helical flute thread mill designed for cutting both internal and external metric threads in a single setup. It produces M18 x 1.50 threads and is coated with TiAlN for extended tool life in ferrous and hardened materials. The 4-flute, right-hand helical design provides efficient chip evacuation during thread milling operations on CNC machining centers. With a 0.49-inch cutting diameter and 1.25-inch length of cut, it handles the full thread depth required for M18 applications. This tool is used by machinists and tooling technicians working in precision manufacturing, job shops, and production environments.

This thread mill is suited for metric thread applications requiring M18 x 1.50 pitch in both through and blind-hole configurations. Its ability to cut internal and external threads with one tool reduces tooling inventory and changeover time. The minimum nominal diameter of 0.7087 inches (18.00 mm) defines the smallest bore it can enter for internal threading. Right-hand flute direction is standard for conventional CNC thread milling programs. It is appropriate for use in steel, alloy steel, cast iron, and similar materials where TiAlN coating provides heat and wear resistance.

Key Features

• Cuts M18 x 1.50 metric internal and external threads with a single tool
• Solid carbide construction for rigidity and dimensional stability
• TiAlN coating provides elevated heat resistance and extended tool life in ferrous materials
• 4 right-hand helical flutes for efficient chip evacuation
• 0.5-inch shank diameter for secure collet or end mill holder retention
• No coolant-through requirement - compatible with flood or external coolant delivery

Compatibility

Designed for CNC machining centers using standard 0.5-inch collet chucks or end mill holders. Suitable for M18 x 1.50 metric thread applications per standard metric thread specifications.

Installation Notes

Installation and operation should be performed by qualified machinists familiar with CNC thread milling cycles. Confirm spindle speed, feed rate, and helical interpolation parameters in the CNC program before running the tool. Secure the 0.5-inch shank in a properly sized collet or end mill holder torqued to the holder manufacturer's specification. Inspect the cutting edges for damage before each use and replace the tool if chipping or coating breakdown is observed.
