Value Collection 70124 Thread Mill 3/4-12 Internal Solid Carbide

Product Description

The VALUE COLLECTION 70124 is a straight flute thread mill designed for cutting internal UNC threads in a single helical pass. Built from solid carbide grade K20C, this tool delivers consistent thread geometry in ferrous and non-ferrous materials where tapping is impractical or where thread quality requirements are high. It carries a 3/4-12 thread profile with 12 teeth per inch, a 0.47 inch cutting diameter, and a 1.1667 inch length of cut. The bright, uncoated finish suits general-purpose applications. Machinists and toolroom operators on CNC machining centers are the primary users of this tool.

This thread mill is suited for producing 3/4-12 UNC internal threads in workpieces machined on CNC vertical or horizontal machining centers with helical interpolation capability. The 1/2 inch shank fits standard ER or precision collet chucks. With five flutes and a 1.1667 inch length of cut, it handles thread depths common in structural and mechanical assemblies. The solid carbide construction makes it appropriate for hardened steels, cast iron, aluminum, and stainless steel applications where tool rigidity is critical.

Key Features

• Solid carbide grade K20C construction for rigidity and wear resistance
• 5 straight flutes for balanced cutting forces during helical interpolation
• 3/4-12 UNC internal thread profile at 12 teeth per inch
• 0.47 inch cutting diameter with 1.1667 inch length of cut
• Bright uncoated finish suitable for a wide range of workpiece materials
• 1/2 inch shank diameter for compatibility with standard collet and end mill holders

Compatibility

Designed for use in CNC machining centers capable of helical interpolation for cutting 3/4-12 UNC internal threads. Accepts 1/2 inch collet or end mill holders.

Installation Notes

Thread milling requires a CNC control with helical interpolation and a correctly programmed thread milling cycle. Ensure the spindle and tool holder are clean and properly torqued before use. Verify that the programmed cutting diameter offsets match the 0.47 inch cutting diameter of this tool. Do not use this tool in manual mills or without a properly configured thread milling subroutine.
