Accupro C911-01024 Thread Mill 10-24 Unc 3 Flute Solid Carbide

Product Description

The ACCUPRO C911-01024 is a solid carbide helical flute thread mill designed for cutting internal 10-24 UNC threads. It runs three right-hand flutes with a 0.14 inch cutting diameter and a 0.3125 inch length of cut, making it suited for tight-tolerance internal thread milling in ferrous and non-ferrous materials. The micrograin carbide substrate supports rigidity and edge retention at higher feed rates. A TiAlN coating reduces heat buildup and extends tool life in demanding machining environments. Machinists and toolroom professionals use this mill where tap breakage is a concern or where thread milling is preferred for process control.

This thread mill is applied in CNC machining centers capable of helical interpolation. It targets internal 10-24 UNC threaded holes in production and job-shop settings across industries including aerospace, automotive, and general manufacturing. The 3/16 inch shank diameter fits standard ER collet chucks and end mill holders common to most vertical and horizontal machining centers. No coolant-through capability is present, so flood or mist coolant applied externally is the standard approach.

Key Features

• Solid micrograin carbide construction for rigidity and edge retention
• TiAlN coating reduces thermal load and extends tool life
• Three right-hand helical flutes for chip evacuation in internal bores
• 0.14 inch cutting diameter sized for 10-24 UNC internal threads
• 0.3125 inch length of cut accommodates standard thread depth requirements
• 3/16 inch shank diameter fits common ER and end mill holder setups

Compatibility

Designed for CNC machining centers with helical interpolation capability; compatible with standard 3/16 inch shank collet chucks and end mill holders used for internal 10-24 UNC thread milling applications.

Installation Notes

Thread milling requires a CNC control programmed for helical interpolation — confirm G-code support before running this tool. Secure the shank fully in a balanced toolholder and verify runout before starting the cut, as excess runout degrades thread quality and shortens tool life. Apply external flood or mist coolant directed at the cutting zone since this tool has no coolant-through provision. Follow your shop's standard lockout procedure before changing or inspecting tooling in the spindle.
