Scientific Cutting Tools SPTM695 Thread Mill 7/8 6 Flute Carbide

Product Description

The SCIENTIFIC CUTTING TOOLS SPTM695 is a single profile thread mill designed for cutting both internal and external threads in the 7/8-8 to 7/8-24 range, covering 8 to 24 TPI. Built from submicron-grade solid carbide with a bright/uncoated finish, it delivers consistent thread geometry across a wide pitch range from a single tool. The 6-flute design supports efficient material removal and smooth surface finish. With a 0.695-inch cutting diameter and a 3/4-inch shank, this tool mounts directly into standard CNC milling setups. Machinists and toolroom professionals use it to thread mill a full thread pitch range without changing tools, reducing setup time on CNC machining centers.

This thread mill is suited for production and job-shop environments running CNC milling machines or machining centers where helical interpolation is available. The single-profile design makes it practical for threading applications where multiple pitch requirements exist within the same bore diameter family. It handles both through and blind-hole internal threads as well as external thread profiles, making it a versatile choice for general-purpose precision machining work across a variety of ferrous and non-ferrous materials when used with appropriate feeds and speeds for the workpiece material.

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 thread profiles
• 6-flute geometry for efficient chip evacuation and surface finish
• Submicron-grade solid carbide construction for rigidity and tool life
• Bright/uncoated finish suitable for a wide range of workpiece materials
• 0.695-inch cutting diameter with 0.490-inch neck for clearance in bored features

Compatibility

Designed for use in CNC machining centers capable of helical interpolation with a 3/4-inch tool holder or collet chuck. Threads cut range from 7/8-8 to 7/8-24 per the tool geometry; confirm compatibility with the target thread standard and material before use.

Installation Notes

Installation and operation of this thread mill should be performed by a qualified CNC machinist or toolroom professional. Secure the 3/4-inch shank in a properly sized collet or end mill holder, ensuring adequate runout tolerance for thread quality. Program helical interpolation paths per the target thread pitch and confirm G-code thread milling cycles before cutting. Never exceed the tool manufacturer's recommended cutting parameters for the workpiece material.
