Scientific Cutting Tools SPTM060L Thread Mill 56-80 Tpi

Product Description

The SCIENTIFIC CUTTING TOOLS SPTM060L is a single profile thread mill designed to cut both internal and external threads across a range from 2-56 to 2-80, covering 56 to 80 TPI. Built from submicron-grade solid carbide with a bright/uncoated finish, this tool delivers precise thread forms in a single helical pass. The cutting diameter is 0.060 inches, the neck diameter is 0.034 inches, and the neck length is 0.200 inches, making it suited for fine-pitch, small-diameter threading work. With 3 flutes and a 0.200-inch length of cut, it is a compact, rigid solution for machinists and tool-and-die professionals running CNC milling operations.

This thread mill is intended for use on CNC machining centers capable of helical interpolation. It handles both internal and external thread applications in a single tool, reducing the need for multiple taps or dies. Typical applications include precision component manufacturing, aerospace and medical part production, and any operation requiring accurate fine-pitch threads in the 2-56 to 2-80 range. The solid carbide construction supports use in ferrous and non-ferrous materials where tight tolerances are required.

Key Features

• Cuts internal and external threads from 2-56 to 2-80 in a single tool
• Submicron-grade solid carbide construction for rigidity and wear resistance
• 3-flute geometry for balanced cutting and chip evacuation in fine-pitch applications
• 0.060-inch cutting diameter with 0.034-inch neck for access to tight bore profiles
• Bright/uncoated finish suitable for a wide range of workpiece materials
• 0.200-inch length of cut optimized for shallow, precise thread engagement

Compatibility

Designed as an OEM-style single profile thread mill for CNC machining centers capable of helical interpolation, suitable for threading operations in the 2-56 to 2-80 thread size range on both internal and external features.

Installation Notes

Installation and operation should be performed by qualified machinists or CNC programmers familiar with helical interpolation thread milling routines. Ensure the tool is properly seated and secured in a compatible collet or toolholder before spindle engagement. Verify CNC program pitch and helix parameters match the target thread specification before cutting. Follow all machine guarding and workholding procedures in accordance with applicable shop safety standards.
