Micro 100 TM-375X Thread Mill 12-32 Tpi 4 Flute Carbide

Product Description

The MICRO 100 TM-375X is a single profile thread mill designed for cutting internal and external threads across a range of 12 to 32 TPI, covering thread sizes from 1/2-12 through 1/2-32. The tool is constructed from brazed solid carbide and features an AlTiN coating for extended tool life in ferrous and hard materials. With a 0.25-inch shank diameter and an overall length of 2.6 inches, the TM-375X is suited for CNC machining centers running helical interpolation cycles. Four flutes provide chip clearance and stable cutting action. This tool is installed and operated by machinists and CNC programmers working in production or job-shop environments.

The TM-375X is well suited for threading operations on both internal bores and external diameters where a single tool must handle multiple thread pitches within the 12 to 32 TPI range. Its compact neck diameter of 0.21 inches allows access into tight bore geometries. Applications include ferrous metals, stainless steels, and other hard materials common in aerospace, industrial, and precision machining work.

Key Features

• Covers 12 to 32 TPI in a single tool, reducing tooling inventory
• Cuts both internal and external threads with one setup
• Brazed solid carbide construction for rigidity and wear resistance
• AlTiN coating improves performance in ferrous and abrasive materials
• Four-flute geometry supports efficient chip evacuation
• 0.21-inch neck diameter provides access to confined bore profiles

Compatibility

Designed as an OEM-style single profile thread mill for use in CNC machining centers capable of helical interpolation, covering the 1/2-12 through 1/2-32 thread size range with a standard 0.25-inch shank interface.

Installation Notes

Installation and operation of this thread mill requires a CNC machining center with helical interpolation capability and a collet or chuck rated for a 0.25-inch shank. Confirm spindle speed, feed rate, and interpolation radius in the CAM program or G-code before cutting. Inspect the brazed joint and cutting edges for damage before each use. Follow shop safety protocols and machine guarding requirements during all threading operations.
