Scientific Cutting Tools SPTM695L Thread Mill 6 Flute Carbide

Product Description

The SCIENTIFIC CUTTING TOOLS SPTM695L is a single profile thread mill designed to cut 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, this tool delivers consistent thread geometry across a broad pitch range without requiring a tool change. The 6-flute configuration supports efficient chip evacuation and smooth cutting action. With a 0.695-inch cutting diameter, a 3/4-inch shank, and a 5-inch overall length, it is sized for CNC machining centers performing precision threading operations in production and job-shop environments.

This thread mill is suited for machinists and CNC operators working in general manufacturing, aerospace, automotive, and tooling applications where 7/8-inch threaded features are required. The single profile design allows one tool to produce multiple pitches within its TPI range on internal bores or external bosses, reducing tooling inventory. The 2.5-inch length of cut and 0.49-inch neck diameter provide clearance for threading deeper features without interference. Licensed machinists and CNC programmers familiar with helical interpolation will find this tool a direct fit for standard threading cycles.

Key Features

• Single profile design covers 8 to 24 TPI - one tool handles multiple pitches in the 7/8-inch thread size range
• Cuts both internal and external threads without changing tools
• Submicron-grade solid carbide construction for rigidity and wear resistance
• 6 flutes for improved chip removal and surface finish
• Bright/uncoated finish suitable for a wide range of workpiece materials
• 0.49-inch neck diameter provides clearance for deeper threaded features

Compatibility

Designed for use in CNC machining centers with helical interpolation capability, compatible with 7/8-inch thread applications ranging from 8 to 24 TPI on both internal and external features.

Installation Notes

This tool is installed by CNC machinists into a compatible tool holder matching the 3/4-inch shank diameter. Confirm runout and tool holder clamping before operation. Threading is performed using a helical interpolation cycle programmed to the specific pitch being cut. Follow the machine tool manufacturer guidelines and applicable shop safety procedures when setting up cutting tools.
