Walter-prototyp 7611462 Helical Flute Thread Mill 3/4-10

Product Description

The WALTER-PROTOTYP 7611462 is a solid carbide helical flute thread mill engineered for cutting internal 3/4-10 UNC threads. With 5 flutes and an AlTiN coating, this tool delivers high cutting performance in ferrous and hardened materials. The 1-1/2 inch length of cut (LOC) suits a range of hole depths common in production machining. At 10 TPI, the tool is purpose-built for standard UNC thread profiles and is well suited to CNC machining centers running interpolated thread milling cycles. Machinists and toolroom technicians working in aerospace, die and mold, or general manufacturing will find it appropriate for both through and blind hole applications where tap breakage risk must be minimized.

This thread mill is designed for internal thread milling on CNC machining centers using helical interpolation. It is appropriate for production and job-shop environments where a single tool must handle threading in materials such as steel, stainless, cast iron, and hardened alloys. The 5-flute geometry supports efficient chip evacuation while maintaining edge stability, making it a practical choice for medium-to-high volume runs as well as prototype work where thread quality and repeatability are critical.

Key Features

• 3/4-10 UNC internal thread profile at 10 TPI for standard UNC fastener compatibility
• 5-flute helical geometry promotes chip evacuation and reduces cutting forces in deep holes
• AlTiN coating provides heat resistance and extended tool life in ferrous and hardened materials
• Solid carbide construction maintains rigidity and accuracy during helical interpolation cycles
• 1-1/2 inch LOC accommodates common hole depth requirements for 3/4-10 threaded fastener applications

Compatibility

Designed as an OEM-style solid carbide thread mill for use on CNC machining centers capable of helical interpolation programmed for internal 3/4-10 UNC thread milling operations.

Installation Notes

Thread mills are installed and run by machinists on CNC machining centers using G-code helical interpolation routines. Ensure the spindle and toolholder are clean and within runout spec before mounting, as excess runout will directly affect thread quality and tool life. Program feed, speed, and stepover values per the manufacturer cutting data for the specific workpiece material. Never use a thread mill in a manual or non-interpolating machine.
