Accupro C911-10008 Thread Mill 1-8 Unc 4 Flute Solid Carbide

Product Description

The ACCUPRO C911-10008 is a helical flute thread mill designed for cutting internal UNC threads in a 1-8 thread size. Built from micrograin solid carbide and coated with TiAlN, it delivers reliable performance in demanding CNC milling applications. The tool features 4 flutes, a 0.735-inch cutting diameter, and a 3/4-inch shank diameter. With 8 teeth per inch and a 1-inch length of cut, it is suited for full-depth internal thread milling in a single helical pass. Machinists and toolroom professionals specify this tool for its rigidity and coating durability in ferrous and high-temperature alloy workpieces.

This thread mill is used in CNC machining centers for producing internal UNC threads in production and jobshop environments. It is appropriate for threading operations in materials where TiAlN coating provides thermal resistance and extended tool life. The 1-inch length of cut accommodates typical thread depths encountered in general machining. No coolant-through capability means external coolant or air blast is used during the operation. Applications include aerospace, automotive, and general industrial component manufacturing where precise internal threads are required.

Key Features

• Micrograin solid carbide construction for rigidity and edge retention
• TiAlN coating provides thermal resistance and extended tool life in ferrous materials
• 4-flute helical design for efficient chip evacuation during internal thread milling
• 0.735-inch cutting diameter with 1-inch length of cut for full-depth UNC thread production
• 3/4-inch shank diameter for secure toolholder retention
• 8 TPI UNC thread form for standard unified coarse thread applications

Compatibility

Designed for use in CNC machining centers equipped with standard 3/4-inch tool holders; produces internal UNC 1-8 threads per the unified coarse thread standard.

Installation Notes

Installation and operation should be performed by a qualified machinist or CNC toolroom professional. Secure the 3/4-inch shank in an appropriate collet or end mill holder and verify runout before cutting. Program the CNC control for a helical interpolation toolpath matched to the 1-8 UNC thread form. Because this tool has no coolant-through capability, confirm that external flood coolant or air blast is directed at the cutting zone to manage heat and chip evacuation.
