Carmex S0375C101.75ISO Thread Mill M12x1.75 Solid Carbide

Product Description

The CARMEX S0375C101.75ISO is a helical flute thread mill designed for cutting internal metric coarse threads to the M12x1.75 standard. Built from solid carbide and coated with TiAlN for heat and wear resistance, this mini-style thread mill is suited for precision threading operations in ferrous and non-ferrous materials. It runs on a 0.375-inch shank, offers a 0.354-inch cutting diameter, and delivers a 1.02-inch length of cut. Licensed machinists and CNC programmers will find this tool well-matched to tight-tolerance internal thread applications on machining centers and CNC mills.

This thread mill is intended for internal threading of M12x1.75 metric coarse holes in production and job-shop environments. Its mini thread mill classification makes it appropriate for applications where tool clearance is limited or bore geometry is constrained. The three-flute configuration supports balanced cutting forces and smooth chip evacuation. It is installed by qualified machinists on CNC machining centers capable of helical interpolation, which is required for thread milling operations.

Key Features

• Solid carbide construction in material grade MT7 for rigidity and long tool life
• TiAlN coating provides thermal barrier and reduces wear at elevated cutting temperatures
• Three helical flutes for balanced cutting load and efficient chip removal
• Mini thread mill type suits tight bore clearances and constrained geometries
• Cuts M12x1.75 metric coarse internal threads in a single helical interpolation pass
• No coolant-through design - external coolant or cutting fluid applied at the spindle

Compatibility

Designed for use on CNC machining centers capable of helical interpolation for cutting M12x1.75 metric coarse internal threads.

Installation Notes

Thread milling requires a CNC machining center programmed for helical interpolation - confirm the control supports this cycle before setup. Secure the 0.375-inch shank in a precision collet or end mill holder and verify runout before cutting. Apply appropriate external cutting fluid for the workpiece material. Never use this tool in a conventional drill press or manual mill; thread milling is a CNC-specific operation.
