Accupro 930-01024 Thread Mill 10-24 Internal Solid Carbide

Product Description

The ACCUPRO 930-01024 is a solid carbide helical flute thread mill designed for cutting internal UNC threads in a single helical pass. Built from micrograin solid carbide and coated with TiAlN for heat and wear resistance, this tool handles 10-24 thread profiles with a cutting diameter of 0.12 inches and a length of cut of 0.3125 inches. The 1/4-inch shank diameter keeps the tool compact and compatible with standard collet chucks and toolholders. With 3 flutes and 24 teeth per inch, it produces clean, accurate threads in ferrous and non-ferrous materials across CNC machining centers.

This thread mill is suited for precision internal threading operations in job shops, production machining, and toolroom environments. The helical interpolation method allows a single tool to produce a range of thread depths and eliminates the risk of tap breakage in blind holes. It is most commonly applied in CNC milling centers programmed with helical thread interpolation cycles. Typical workpiece materials include steel, stainless steel, aluminum, and cast iron where a UNC 10-24 internal thread is required.

Key Features

• Solid micrograin carbide construction for rigidity and long tool life
• TiAlN coating provides thermal protection and extended wear resistance in ferrous materials
• 3-flute design balances chip clearance and cutting stability
• 0.12 inch cutting diameter with 0.3125 inch length of cut for 10-24 UNC internal threads
• 1/4 inch shank diameter fits standard collet chucks and shrink-fit holders
• No coolant-through requirement simplifies setup on standard CNC machines

Compatibility

Designed for CNC milling machines capable of helical thread interpolation and producing UNC 10-24 internal threads in the appropriate pre-drilled or bored hole size.

Installation Notes

Installation and operation should be performed by a qualified CNC machinist or tooling specialist. Ensure the tool is properly seated and secured in the collet or toolholder to the correct clamping torque per holder manufacturer specifications before running. Program the CNC controller with a helical interpolation cycle matched to the 10-24 UNC thread pitch and verify the pre-drill diameter is correct for the thread form before engaging the cutter. Inspect the cutting edge condition before each use and replace the tool at the first sign of edge wear to maintain thread quality.
