Scientific Cutting Tools SPTM695LA Thread Mill 6 Flutes

Product Description

The SCIENTIFIC CUTTING TOOLS SPTM695LA is a single profile thread mill engineered for cutting both internal and external threads in the 7/8-8 to 7/8-24 thread size range, covering 8 to 24 TPI. Built from submicron solid carbide and finished with an AlTiN+ coating, this tool delivers wear resistance and thermal stability in demanding machining environments. It features 6 flutes, a 0.695-inch cutting diameter, a 3/4-inch shank diameter, and a 5-inch overall length with a 2.5-inch length of cut. Licensed machinists and CNC operators rely on this tool for precision thread milling in ferrous and hard materials.

This thread mill is suited for use in CNC machining centers where a single tool must produce multiple thread pitches across the 7/8 thread size family, eliminating the need for multiple taps. It performs in both internal thread applications such as blind holes and through holes, and external thread applications on shafts or bosses. The 0.490-inch neck diameter provides clearance for deep-reach thread milling operations, making it a practical choice for aerospace, mold and die, and precision parts manufacturing environments.

Key Features

• Covers 7/8-8 to 7/8-24 thread range (8 to 24 TPI) with a single tool
• Cuts both internal and external threads
• Submicron solid carbide construction for rigidity and long tool life
• AlTiN+ coating for high-temperature resistance and reduced wear
• 6 flutes for improved surface finish and chip evacuation
• 0.490-inch neck diameter provides clearance for deep-reach applications

Compatibility

Designed for use in CNC machining centers with a 3/4-inch tool holder or collet; suitable for producing 7/8-series threads across the 8 to 24 TPI range in a single setup.

Installation Notes

Installation and operation should be performed by a qualified CNC machinist or tooling specialist. Secure the 3/4-inch shank in a properly sized collet or end mill holder rated for milling applications before use. Verify spindle speed, feed rate, and helical interpolation parameters in the CNC program prior to cutting. Inspect the cutting edge and coating condition before each use and replace the tool if chipping or coating breakdown is observed.
