Scientific Cutting Tools Tm 450-10 Thread Mill 3/4-10 Unc

Product Description

The SCIENTIFIC CUTTING TOOLS TM 450-10 is a straight flute thread mill designed for cutting internal UNC threads at 3/4-10 (10 teeth per inch). Built from submicron-grade solid carbide, it delivers consistent thread geometry in demanding machining environments. The tool features a 0.45-inch cutting diameter, 1.14-inch length of cut, and a 0.5-inch shank diameter, making it a rigid, single-point-style solution for CNC milling operations. The bright, uncoated finish suits a wide range of work materials where coating interaction is a concern. Machinists and CNC programmers in job shops, production facilities, and aerospace or industrial manufacturing environments are the primary users.

This thread mill is suited for internal threading operations where a single tool must produce a full 3/4-10 UNC thread profile in a pre-drilled bore. It is used on CNC machining centers capable of helical interpolation. The 4-flute straight flute design provides clean chip evacuation for the length of cut. With an overall length of 3.5 inches, the tool has the reach needed for standard fixture setups without excessive overhang. It is appropriate for threading in aluminum, steel, stainless, and other machinable alloys where carbide tooling is specified.

Key Features

• Submicron-grade solid carbide construction for rigidity and edge retention
• Straight flute design with 4 flutes for stable cutting action on internal threads
• Cuts 3/4-10 UNC internal threads at 10 TPI in a single helical pass
• Bright uncoated finish compatible with a broad range of workpiece materials
• 0.45-inch cutting diameter with 1.14-inch length of cut for standard bore depths
• No coolant-through requirement simplifies tool setup on standard spindles

Compatibility

Designed for use on CNC machining centers capable of helical interpolation to produce 3/4-10 UNC internal threads. No specific machine model compatibility is stated by the manufacturer.

Installation Notes

Installation and use of this tool should be performed by qualified machinists or CNC programmers familiar with thread milling operations and helical interpolation routines. Ensure the tool is properly seated and torqued in an appropriate collet or end mill holder before spindle engagement. Verify that the machine spindle is fully stopped before changing or inspecting the tool. Follow all applicable shop safety protocols and machine tool manufacturer guidelines when programming thread milling cycles.
