Allied TM14150 Thread Mill M14x1.5 4 Flute Solid Carbide

Product Description

The ALLIED MACHINE AND ENGINEERING TM14150 is a helical flute thread mill designed for cutting M14x1.5 metric threads in both internal and external applications. Built from solid carbide and finished with a TiAlN coating, this tool delivers the wear resistance and heat tolerance required for production threading in steel, stainless, and hard alloys. The 4-flute right-hand configuration supports efficient chip evacuation while maintaining thread form accuracy. The cutting diameter is 0.3700 inches with a length of cut of 0.8750 inches, making it well suited for threading operations where a single tool must handle both bore threading and external boss threading in one setup.

This thread mill is used in machining centers and CNC milling applications where metric M14x1.5 threads are required. It is appropriate for job shops, aerospace, automotive, and general metalworking environments that demand consistent thread quality across internal and external features. The helical flute geometry allows the tool to interpolate the full thread form in a single helical pass, reducing cycle time compared to single-point threading. At 3.5000 inches overall length with a 3/8-inch shank, it fits standard ER and end mill holders common in most CNC spindles.

Key Features

• Cuts M14x1.5 metric threads in both internal and external configurations with a single tool
• Solid carbide construction provides rigidity and dimensional stability at elevated cutting speeds
• TiAlN coating extends tool life in ferrous materials and elevated-temperature cutting conditions
• 4-flute right-hand helical geometry promotes clean chip flow and consistent thread finish
• No coolant-through design simplifies setup on standard machining centers without high-pressure coolant systems
• 3/8-inch shank diameter fits widely available ER collet chucks and end mill holders

Compatibility

Designed for use in CNC machining centers capable of helical interpolation for M14x1.5 metric thread milling in internal and external applications.

Installation Notes

Thread milling with this tool requires a CNC machining center programmed for helical interpolation — verify G-code thread milling cycles are supported by the control before use. Secure the 3/8-inch shank in a properly sized collet or end mill holder and confirm runout before cutting. Follow the tool manufacturer feed, speed, and interpolation radius recommendations for the workpiece material; do not exceed the rated cutting diameter offset. Inspect the cutting edges before each use, as carbide tooling is susceptible to chipping if dropped or improperly stored.
