Iscar 5603930 Thread Mill 3 Flute Tialn 8 Tpi Solid Carbide

Product Description

The ISCAR 5603930 is a solid carbide helical flute thread mill designed for external UN thread milling operations. It features 3 right-hand flutes and cuts at 8 teeth per inch (TPI) with a cutting diameter of 0.630 inches and a length of cut of 1.700 inches. The tool carries a TiAlN coating for improved wear resistance and heat tolerance at elevated cutting speeds. With an overall length of 4.000 inches and a shank diameter of 5/8 inch, it is sized for rigid setups on CNC machining centers. Licensed machinists and tooling specialists working in precision threading applications are the primary users of this tool.

This thread mill is suited for external UN thread milling on ferrous and non-ferrous workpiece materials. The helical flute geometry allows the tool to engage progressively along the thread form, reducing cutting forces compared to single-point threading tools. It is appropriate for use in production environments where repeatable thread quality and tool life are priorities. The minimum nominal diameter this tool can produce is 0.900 inches.

Key Features

• Solid carbide construction for rigidity and wear resistance in demanding thread milling operations
• TiAlN coating extends tool life at higher cutting temperatures
• 3 right-hand helical flutes for progressive thread engagement and reduced cutting forces
• 8 TPI cutting geometry for UN external thread standard
• 0.630 inch cutting diameter with 1.700 inch length of cut for threading depth flexibility
• No coolant-through design — suitable for flood or external coolant delivery setups

Compatibility

Designed for external UN thread milling with a minimum nominal diameter of 0.900 inches. Intended for use in CNC machining centers with appropriate toolholding for a 5/8 inch shank diameter.

Installation Notes

This tool should be installed in a properly sized collet or toolholder rated for the 5/8 inch shank diameter and secured to the torque specification recommended by the toolholder manufacturer. Verify CNC program thread mill cutter compensation and helical interpolation settings before first cut. Inspect the cutting edges for chips or coating damage before mounting. Handle solid carbide tooling carefully to avoid edge damage from contact with hard surfaces.
