Carmex MT0500C1410UN Thread Mill 3/4-10 Solid Carbide

Product Description

The CARMEX MT0500C1410UN is a solid carbide helical flute thread mill designed for cutting internal UNC threads at a 3/4-10 specification. Built from Material Grade MT7 carbide and finished with a TiAlN coating, it delivers heat resistance and wear life suited to production and job-shop environments. The tool runs with a right-hand flute direction, carries three flutes, and produces a 0.4720-inch cutting diameter with a 1.3500-inch length of cut. It is installed and operated by CNC machinists and tool-and-die professionals working with machining centers capable of helical interpolation.

This thread mill is intended for internal thread milling operations on UNC 3/4-10 threads in materials compatible with MT7-grade solid carbide tooling. It fits standard 1/2-inch shank tool holders and is suited for use in vertical and horizontal machining centers. The 3.5000-inch overall length provides clearance for deeper workpiece setups. Applications span precision part manufacturing, fixture work, and repair threading where tap breakage risk makes thread milling the preferred method.

Key Features

• Solid carbide MT7 grade construction for rigidity and long tool life in difficult materials
• TiAlN coating improves heat resistance and reduces tool wear at elevated cutting speeds
• Three right-hand helical flutes for efficient chip evacuation during internal thread milling
• 0.4720-inch cutting diameter with 1.3500-inch length of cut for full UNC 3/4-10 thread profile
• No coolant-through design - external coolant or minimum quantity lubrication applied at spindle
• 10 teeth per inch matching the 3/4-10 UNC thread standard

Compatibility

Designed for internal UNC 3/4-10 thread milling operations using standard 1/2-inch shank tool holders on CNC machining centers with helical interpolation capability.

Installation Notes

Thread mills are installed by qualified CNC machinists - verify that the machining center control supports helical interpolation before programming. Secure the 1/2-inch shank in a matched collet or end mill holder torqued per the toolholder manufacturer specification. Confirm workpiece is fixtured and machine is in a safe ready state before spindle engagement. Follow the tooling manufacturer feed and speed recommendations for the specific workpiece material and do not exceed the rated cutting diameter.
