Scientific Cutting Tools SPTM488 Thread Mill 5/8-11 to 5/8-32

Product Description

The SCIENTIFIC CUTTING TOOLS SPTM488 is a single profile thread mill designed to cut both internal and external threads across a wide range from 5/8-11 to 5/8-32, covering 11 to 32 TPI. Built from submicron-grade solid carbide, it delivers the wear resistance and edge stability required for accurate thread forming in hard or abrasive materials. With 5 flutes and a 0.488-inch cutting diameter, the tool produces clean thread profiles in a helical interpolation path using a standard CNC machining center. The bright, uncoated finish makes it well suited for non-ferrous metals and materials where coating adhesion is not a priority.

This thread mill is suited for machine shops, tool rooms, and production environments where a single tool must cover a broad TPI range without a tool change. The 1/2-inch shank diameter fits standard ER or side-lock holders common in CNC machining centers. The 3.5-inch overall length and 0.85-inch neck length provide clearance for threading blind or through holes where reach is a factor. It handles both internal and external thread profiles, reducing tooling inventory in shops running mixed threading operations.

Key Features

• Cuts internal and external threads from 5/8-11 to 5/8-32 with a single tool
• Submicron-grade solid carbide construction for extended edge life
• 5-flute geometry supports efficient chip evacuation during thread milling
• 0.488-inch cutting diameter with 0.34-inch neck diameter for clearance in tight bores
• Bright/uncoated finish suitable for non-ferrous and other compatible workpiece materials
• 3.5-inch overall length accommodates applications requiring additional reach

Compatibility

Designed for use in CNC machining centers with helical interpolation capability; fits standard 1/2-inch shank toolholders and covers thread sizes from 5/8-11 to 5/8-32 for internal and external applications.

Installation Notes

Thread mills of this type are installed and run by machinists on CNC milling or machining center equipment programmed for helical interpolation. Confirm that the toolholder is clean and the shank is fully seated before clamping. Verify spindle speed, feed rate, and helical pitch in the CAM program against the specific workpiece material before cutting. Do not use this tool in manual milling machines or without proper CNC thread milling cycles.
