Accupro 930-00632 Thread Mill 6-32 Unc 2 Flute Solid Carbide

Product Description

The ACCUPRO 930-00632 is a solid carbide helical flute thread mill designed for cutting internal 6-32 UNC threads. It runs 2 flutes in a helical geometry to generate clean, accurate thread profiles in a single interpolated pass. The cutting diameter is 0.115 inches and the length of cut is 0.25 inches, making it well suited for shallow-depth internal thread applications. The tool is ground from micrograin carbide stock and finished with a TiAlN coating to extend wear life at elevated cutting temperatures. Machinists and tool and die professionals install this tool in CNC machining centers equipped with helical interpolation capability.

This thread mill is used for producing 6-32 UNC internal threads in materials where the TiAlN coating provides a thermal barrier advantage, such as hardened steels, stainless alloys, and high-temp materials. The 1/4-inch shank diameter fits standard collets and tool holders commonly found in vertical and horizontal machining centers. Its compact cutting diameter allows thread milling in tight-clearance bores and close-proximity features where a traditional tap would create interference or breakage risk.

Key Features

• 6-32 UNC internal thread profile, 32 teeth per inch
• 0.115 inch cutting diameter for tight-bore applications
• 0.25 inch length of cut for shallow internal thread engagement
• 2-flute helical geometry for chip evacuation in interpolated threading passes
• TiAlN coating for extended tool life in abrasive and high-temperature materials
• Micrograin solid carbide construction for dimensional stability and edge retention

Compatibility

Designed for use in CNC machining centers with helical interpolation capability and standard 1/4-inch collet or tool holder systems for internal 6-32 UNC thread milling operations.

Installation Notes

Installation and operation of this tool is performed by machinists or CNC operators. Secure the 1/4-inch shank in a balanced collet or shrink-fit holder with appropriate runout tolerance before use. Program the machine for helical interpolation at the correct pitch and diameter offset per the 6-32 UNC thread specification. Do not use this tool as a tap or in non-interpolating machines, as straight plunge loading will damage the flute geometry and may fracture the carbide body.
