Vargus 80063 Straight Flute Thread Mill 1/2-12 Solid Carbide

Product Description

The VARGUS 80063 is a straight flute thread mill designed for cutting 1/2-12 BSW threads in both external and internal applications. Built from micrograin solid carbide and coated with TiAlN, it handles demanding thread milling operations where tool life and surface finish matter. The cutter runs 3 flutes with a 0.31 inch cutting diameter and a 0.75 inch length of cut, delivering consistent thread geometry across a range of materials. Overall length is 2.48 inches. This tool is installed and operated by machinists and CNC programmers working in precision machining, toolroom, or production environments.

The 80063 suits CNC machining centers running thread mill cycles on ferrous and non-ferrous workpieces where a single tool must handle both external boss threads and internal bore threads. With a 5/16 inch shank diameter and compact 2.48 inch overall length, it fits standard ER collet chucks and small-bore tool holders common in vertical and horizontal machining centers. The TiAlN coating improves heat resistance during dry or minimum-quantity lubrication cutting, making it a practical choice for production runs as well as prototype work.

Key Features

• Cuts 1/2-12 BSW threads externally and internally with a single tool
• Micrograin solid carbide substrate for rigidity and wear resistance
• TiAlN coating for elevated heat resistance and extended tool life
• 3-flute geometry with 0.31 inch cutting diameter and 0.75 inch length of cut
• 5/16 inch shank diameter compatible with standard ER collet systems
• No coolant-through design suited for external coolant or MQL delivery

Compatibility

Designed for use in CNC machining centers with standard collet or milling chuck toolholders accepting a 5/16 inch straight shank. Suitable for thread milling 1/2-12 BSW threads in external and internal configurations.

Installation Notes

Thread mills must be loaded into a runout-checked collet or chuck and programmed with a helical interpolation cycle matched to the 1/2-12 thread pitch. Verify shank seating depth and tool projection before running. Confirm spindle speed, feed rate, and radial step-over are set per the tool manufacturer recommendations for the workpiece material. Always confirm the machine tool path direction matches the intended thread hand before cutting.
