Accupro C931-06100 Internal Thread Mill 3 Flute Solid Carbide

Product Description

The ACCUPRO C931-06100 is a solid carbide internal helical flute thread mill designed for producing metric coarse internal threads in a single helical pass. Built from micrograin solid carbide and finished with a TiAlN coating, this tool delivers hardness and heat resistance suited to production and job-shop environments. It features 3 right-hand flutes, a cutting diameter of 0.17 inches (4.50 mm), a shank diameter of 3/16 inches (6.00 mm), and a length of cut of 0.5 inches. Machinists and toolroom technicians install this tool in CNC machining centers capable of helical interpolation.

This thread mill is configured for M6 x 1.00 metric coarse internal threads with a minimum nominal bore diameter of 0.2362 inches (6.00 mm). It is suited for use in ferrous and non-ferrous materials where TiAlN coating provides thermal protection during high-speed cutting cycles. Typical applications include threading operations in production machining, mold and die work, and general metalworking where a solid carbide tool and helical interpolation strategy are required. Coolant-through is not supported on this tool.

Key Features

• Micrograin solid carbide substrate for rigidity and wear resistance in threading applications
• TiAlN coating provides heat resistance and extends tool life in dry and semi-dry cutting conditions
• 3 right-hand helical flutes for efficient chip evacuation during internal thread milling
• M6 x 1.00 metric coarse thread profile with 1.00 mm pitch
• Shank diameter tolerance of 0.0003 inches for accurate toolholder fitment
• No coolant-through design keeps setup straightforward for standard toolholders

Compatibility

Designed for use in CNC machining centers capable of helical interpolation and compatible with standard toolholders accepting a 3/16 inch (6.00 mm) shank diameter. Suited for M6 x 1.00 metric coarse internal threading applications.

Installation Notes

Installation and operation of this thread mill should be performed by a qualified machinist or toolroom technician familiar with CNC helical interpolation programming. Ensure the toolholder is clean and the shank is fully seated and torqued to the holder manufacturer's specification before running. Verify spindle speed, feed rate, and helical pitch values in the CNC program prior to cutting. Do not use this tool for external threading or in manual machining setups not capable of helical interpolation.
