Scientific Cutting Tools TM600-16N Thread Mill 3/4-16 Unf

Product Description

The SCIENTIFIC CUTTING TOOLS TM600-16N is a straight flute thread mill designed to cut 3/4-16 UNF threads in both external and internal configurations. Built from powdered metal and finished with a TiCN coating, it delivers hardness and heat resistance suited for production threading in ferrous and non-ferrous materials. The tool runs a 0.6-inch cutting diameter, a 1.088-inch length of cut, and a 4-inch overall length, making it a capable choice for threading operations on CNC machining centers. Machinists and toolroom professionals use this mill where tap breakage is a concern or where a single tool must handle both internal and external thread forms.

This thread mill is suited for CNC milling operations requiring 3/4-16 UNF threads at production volumes. The 5/8-inch shank diameter provides rigid tool holding in standard ER and end mill collet systems. Its straight flute geometry works well in through-hole and blind-hole applications where chip evacuation can be managed through programmed feed and speed parameters. The TiCN coating extends tool life when cutting mild steel, alloy steel, aluminum, and similar materials commonly encountered in general machining and repair work.

Key Features

• Cuts 3/4-16 UNF threads in both external and internal configurations with a single tool
• TiCN coating increases surface hardness and reduces heat buildup during cutting
• Powdered metal substrate provides consistent grain structure and wear resistance
• 6-flute straight design supports stable cutting action across a range of materials
• 1.088-inch length of cut accommodates standard thread engagement depths
• 5/8-inch shank fits common collet and end mill holder systems on CNC machining centers

Compatibility

Designed for use in CNC machining centers with helical interpolation capability. Fits standard 5/8-inch collet chucks and end mill holders. Intended for 3/4-16 UNF thread milling applications in external and internal configurations.

Installation Notes

Thread milling requires a CNC machining center with helical interpolation; verify control compatibility before programming. Secure the shank fully in a matched collet or end mill holder and confirm runout before cutting. Follow the tool manufacturer and machine builder guidelines for spindle speed, feed rate, and depth of cut for the workpiece material. Coolant-through is not available on this tool, so direct flood or mist coolant at the cutting zone to manage chip evacuation and heat.
