Carmex B0625E1414UN Thread Mill 7/8-14 Unf 5 Flute Carbide

Product Description

The CARMEX B0625E1414UN is a solid carbide helical flute thread mill designed for cutting internal 7/8-14 UNF threads in a single helical pass. It features a 5-flute, right-hand configuration with a 0.625-inch cutting diameter and a 1.46-inch length of cut. The TiAlN coating improves heat resistance and tool life in ferrous and high-strength materials. Coolant-through capability supports chip evacuation at depth. This tool is used by machinists and CNC operators in production and job-shop environments where thread milling is preferred over tapping for accuracy, thread quality, or difficult materials.

This thread mill is suited for internal UNF threading operations on CNC machining centers. It handles the 7/8-14 thread size in materials classified under grade MT7. With a 0.625-inch shank diameter and a 4-inch overall length, it fits standard toolholders used in vertical and horizontal machining centers. The 2.54-inch shank length provides adequate grip depth for secure clamping. Thread milling with this tool allows a single cutter to produce the finished thread form in one interpolated path, reducing tool count in mixed-thread jobs.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard and abrasive materials
• TiAlN coating for elevated heat resistance and extended tool life in ferrous alloys
• Coolant-through design directs coolant to the cutting zone for effective chip evacuation
• 5 right-hand flutes provide smooth cutting action and improved surface finish
• 14 TPI UNF thread form matches standard 7/8-14 internal thread specifications
• 4-inch overall length with 0.625-inch shank fits common CNC toolholder styles

Compatibility

Designed as an OEM-style thread milling tool for internal 7/8-14 UNF thread applications on CNC machining centers using standard 0.625-inch bore toolholders.

Installation Notes

Installation and operation of this tool should be performed by qualified machinists or CNC programmers. Secure the shank fully into a collet or milling chuck to the recommended grip depth before running spindle. Program the tool path using helical interpolation per the machine control and thread specification requirements. Verify coolant flow through the spindle before engaging the cut, and confirm spindle speed and feed rate match the workpiece material and tool manufacturer recommendations.
