Scientific Cutting Tools TMLR100-32EL Thread Mill 6-32

Product Description

The SCIENTIFIC CUTTING TOOLS TMLR100-32EL is a solid carbide helical flute thread mill designed for cutting internal UNC threads in a CNC milling environment. It produces 6-32 threads at 32 teeth per inch with a 0.1 inch cutting diameter and a 0.4 inch length of cut. The long-reach geometry and 3-flute right-hand configuration make it well suited for threading small-diameter holes where tap access is limited or where thread quality and tool life must be consistent across production runs. Machinists and CNC operators working in precision manufacturing, aerospace, and mechanical assembly rely on this tool for accurate internal thread production.

This thread mill is intended for internal threading operations on 6-32 UNC holes in a variety of workpiece materials. The submicron carbide grade provides the hardness and edge retention needed for demanding cuts in steel, aluminum, and engineered plastics. The bright, uncoated finish works across a broad range of materials without the risk of built-up edge from coating interactions. At 2.5 inches overall length with a 0.25 inch shank diameter, it fits standard CNC machining center collets and tool holders commonly used in job shop and production floor setups.

Key Features

• Cuts 6-32 UNC internal threads at 32 TPI with a 0.1 inch cutting diameter
• 3-flute right-hand helical design for smooth chip evacuation in small bores
• Long-reach configuration allows threading in recessed or deep hole applications
• Submicron solid carbide grade delivers consistent edge life across production runs
• Bright, uncoated finish suitable for use in a wide range of workpiece materials
• No coolant-through requirement simplifies setup on standard machining centers

Compatibility

Designed as an OEM-style thread mill for CNC machining centers equipped with standard collet or end mill tool holders accepting a 0.25 inch shank diameter, used to produce 6-32 UNC internal threads.

Installation Notes

This tool is installed and operated by CNC machinists or toolroom personnel on CNC milling machines or machining centers. Confirm proper shank clamping torque per the tool holder manufacturer specifications before running. Program the helical interpolation path in the CNC control to match the 6-32 thread pitch and cutting diameter. Verify spindle speed, feed rate, and depth of cut against the tool manufacturer cutting data before beginning production cuts.
