Scientific Cutting Tools TM28027NPTTIN/C Thread Mill 1/8-27 Npt

Product Description

The SCIENTIFIC CUTTING TOOLS TM28027NPTTIN/C is a straight flute thread mill designed to cut 1/8-27 NPT threads in both external and internal applications. Built from submicron-grade solid carbide and coated with TiAlN for heat and wear resistance, this tool delivers consistent thread quality in ferrous and non-ferrous materials. It runs 4 flutes with a 0.28-inch cutting diameter, a 0.758-inch length of cut, and a 3/8-inch straight shank. Machinists and tool-and-die professionals use this mill on CNC machining centers where helical interpolation is available. The NPT taper thread profile makes it well suited for pipe fitting applications across plumbing, pneumatic, and hydraulic work.

This thread mill is intended for shops producing or repairing 1/8-27 NPT threaded connections in production or maintenance environments. At 3.5 inches overall length with a 3/8-inch shank, it fits standard ER and side-lock toolholders common to vertical and horizontal machining centers. The straight flute geometry and submicron carbide substrate make it a reliable choice when threading materials that demand tool rigidity and edge integrity. No coolant-through capability means external flood or mist coolant is the standard approach for chip evacuation and thermal management during the cut.

Key Features

• Cuts 1/8-27 NPT threads in both external and internal configurations in a single tool
• Submicron-grade solid carbide substrate for rigidity and edge retention
• TiAlN coating improves heat resistance and extends tool life in demanding materials
• 4 straight flutes with 27 TPI for consistent NPT thread form
• 0.758-inch length of cut accommodates standard NPT thread engagement depths
• 3/8-inch shank diameter fits common ER collet and side-lock toolholder systems

Compatibility

Designed for use on CNC machining centers capable of helical interpolation. Cuts 1/8-27 NPT thread form in external and internal applications. The 3/8-inch straight shank is compatible with standard ER collet chucks and side-lock toolholders.

Installation Notes

Thread milling requires a CNC control with helical interpolation capability - confirm machine compatibility before setup. Secure the shank fully within the toolholder to the recommended gauge depth to minimize runout and deflection. Use external flood or mist coolant directed at the cutting zone for chip evacuation, as this tool does not have coolant-through capability. Verify programmed thread pitch and interpolation direction before running the first part.
