Walter-prototyp 6580450 Thread Mill 5/16-24 Internal Carbide

Product Description

The WALTER-PROTOTYP 6580450 is a solid carbide helical flute thread mill designed for cutting internal UNF threads to a 5/16-24 specification. It runs 4 right-hand flutes with a TiAlN coating for heat and wear resistance at elevated cutting speeds. The shank diameter measures 0.236 inches and the cutting diameter is also 0.236 inches, giving it a consistent profile from shank to cutting zone. Coolant-through capability helps evacuate chips and manage heat during deep or tight-tolerance thread milling operations. Machinists and tool-and-die professionals use this tool on CNC machining centers where single-point thread milling is preferred over tapping.

This thread mill is suited for internal thread generation in ferrous and non-ferrous workpiece materials where thread quality and tool life are priorities. At 24 teeth per inch and a 0.625-inch length of cut, it handles standard 5/16-24 UNF thread depths found in precision mechanical assemblies, aerospace components, and general manufacturing fixtures. The 2.244-inch overall length provides adequate clearance for most standard tool holders and spindle setups.

Key Features

• Solid carbide construction for rigidity and extended tool life
• TiAlN coating provides thermal protection and wear resistance at high cutting speeds
• 4 right-hand helical flutes for efficient chip evacuation
• Coolant-through design supports high-feed internal thread milling
• Cuts 5/16-24 UNF internal threads at 24 TPI
• Consistent 0.236-inch shank and cutting diameter for straightforward tool holder setup

Compatibility

Designed for CNC machining centers capable of helical interpolation; cuts internal 5/16-24 UNF threads and is intended as a direct-use or replacement thread mill for applications requiring that thread form and pitch.

Installation Notes

Installation is performed by qualified machinists or CNC programmers. Secure the shank in a compatible collet or end mill holder rated for the 0.236-inch shank diameter before use. Verify spindle speed, feed rate, and helical interpolation path in the CNC program before engaging the workpiece. Confirm coolant-through supply is active and at adequate pressure prior to initiating the cut.
