Scientific Cutting Tools TM27527NPTTIN/C Thread Mill 1/8-27 Npt

Product Description

The SCIENTIFIC CUTTING TOOLS TM27527NPTTIN/C is a straight flute thread mill designed to cut 1/8-27 NPT threads in both external and internal configurations. Built from submicron-grade solid carbide and finished with a TiN coating, this tool delivers consistent thread form in ferrous and non-ferrous materials. It features 4 staggered flutes and a 0.275 inch cutting diameter with a length of cut of 0.758 inches. The 3/8 inch shank diameter accepts standard toolholder collets common in CNC machining centers. Machinists and tool-and-die professionals working with pipe thread applications will find this mill ready for demanding production environments.

This thread mill is suited for CNC machining operations requiring accurate NPT pipe threads in tight-tolerance components. The 1/8-27 NPT designation makes it appropriate for fluid and gas fittings, valve bodies, and instrumentation ports common in plumbing, HVAC, and industrial assembly. Its straight flute geometry and staggered tooth design support stable cutting in a range of workpiece materials. Overall length of 3.5 inches provides clearance for most standard setups.

Key Features

• Cuts 1/8-27 NPT threads in both external and internal applications
• Submicron-grade solid carbide construction for rigidity and wear resistance
• TiN coating extends tool life and reduces friction during cutting
• Staggered tooth geometry promotes chip evacuation and cutting stability
• 4 straight flutes with 27 teeth per inch for accurate thread form
• No coolant-through design - suitable for flood or mist coolant applied externally

Compatibility

Designed for use in CNC machining centers with 3/8 inch collet or end mill toolholders capable of helical interpolation for NPT pipe thread milling operations.

Installation Notes

Thread milling requires a CNC machining center with helical interpolation capability. Secure the tool in a properly sized 3/8 inch collet or toolholder and verify runout before cutting. Program the correct helical interpolation path for the 1/8-27 NPT thread form per the machine control and tool manufacturer guidelines. Apply appropriate flood or mist coolant externally, as this tool does not support coolant-through delivery.
