Scientific Cutting Tools SPTM595LA Thread Mill 6 Flute Carbide

Product Description

The SCIENTIFIC CUTTING TOOLS SPTM595LA is a single profile thread mill engineered for cutting both internal and external threads in the 3/4-10 to 3/4-32 range, covering 10 to 32 TPI. Built from submicron-grade solid carbide and finished with an AlTiN+ coating, this tool delivers high-heat resistance and extended tool life in demanding machining environments. The 6-flute geometry provides efficient chip evacuation and stable cutting action. With a 0.595-inch cutting diameter, a 0.430-inch neck diameter, and a 2-inch length of cut, it handles a wide thread pitch range from a single tool, reducing the need for multiple dedicated thread mills in a job setup.

This thread mill is suited for CNC machining centers performing precision threading operations on ferrous and hard materials in both production and job-shop environments. The single profile design allows one tool to cover the full 3/4-inch thread size range across both coarse and fine pitches, making it practical for shops that machine varied thread specifications in steel, stainless, and similar alloys. Its 5/8-inch shank diameter and 4-inch overall length are compatible with standard ER and hydraulic collet toolholders commonly found in vertical and horizontal machining centers.

Key Features

• Cuts internal and external threads from 3/4-10 to 3/4-32 with a single tool
• AlTiN+ coating provides high-temperature resistance and wear protection
• Submicron-grade solid carbide substrate for rigidity and edge retention
• 6-flute design supports efficient chip evacuation during thread milling operations
• 0.430-inch neck diameter provides clearance for deep thread milling in bores
• 2-inch length of cut accommodates a full range of thread engagement depths

Compatibility

Designed for use in CNC machining centers with standard 5/8-inch collet or toolholder systems capable of helical interpolation; compatible with 3/4-inch thread specifications spanning 10 to 32 TPI on both internal and external features.

Installation Notes

Thread milling requires a CNC control capable of helical interpolation; verify the machine program and toolpath before cutting. Secure the shank fully in a balanced collet or hydraulic holder to minimize runout, which directly affects thread quality. Follow the tool manufacturer recommended speeds and feeds for the specific workpiece material and coating type. Inspect the cutting edges before each use and replace at the first sign of chipping or coating wear.
