Walter-prototyp 6580452 Thread Mill 9/16-18 Unf 5 Flute

Product Description

The WALTER-PROTOTYP 6580452 is a solid carbide helical flute thread mill designed for cutting internal UNF threads to a 9/16-18 specification. It runs 5 right-hand flutes with an 18 TPI profile and carries a TiAlN coating for heat resistance and extended tool life in ferrous and non-ferrous materials. The shank diameter is 10.00 mm (0.394 inches), the cutting diameter is 10.00 mm (0.394 inches), and the overall length is 80.00 mm (3.15 inches). Coolant-through capability supports chip evacuation in deep or blind-hole applications. This tool is sized for CNC machining centers and is installed by machinists and tool-and-die professionals working in precision threading operations.

This thread mill is suited for internal thread milling on CNC vertical and horizontal machining centers in production and job-shop environments. The 9/16-18 UNF thread form makes it appropriate for aerospace, automotive, hydraulic, and general mechanical assembly applications where fine-thread internal features are required. The helical flute geometry and TiAlN coating support use in a range of work materials including alloy steels, stainless steels, and aluminum. Coolant-through delivery aids in chip management when threading blind holes or holes with limited clearance.

Key Features

• Solid carbide construction for rigidity and wear resistance in precision threading
• TiAlN coating extends tool life and supports higher cutting temperatures
• Coolant-through design improves chip evacuation in blind and deep-hole applications
• 5 right-hand helical flutes for smooth thread form and reduced cutting forces
• 10.00 mm shank diameter with 40.00 mm shank length (1.575 inches) for secure toolholder engagement
• 29.63 mm (1.167 inches) length of cut accommodates standard thread depth requirements for 9/16-18 UNF features

Compatibility

Designed for use in CNC machining centers with ER or shrink-fit toolholders accepting a 10.00 mm shank diameter. Intended for internal thread milling of 9/16-18 UNF features in precision machined components.

Installation Notes

Installation and operation are performed by qualified machinists on CNC machining equipment. Confirm toolholder runout is within acceptable tolerance before use, as excessive runout will degrade thread quality and tool life. Ensure the coolant-through circuit in the spindle is active and delivering adequate pressure before starting the cut. Never use this tool in a manual machine or handheld application.
