Sandvik Coromant 5743832 Thread Mill 7/16-20 Internal Tialn

Product Description

The SANDVIK COROMANT 5743832 is a solid carbide helical flute thread mill designed for cutting internal UNF threads to a 7/16-20 specification. With 4 flutes in a right-hand helix configuration and a TiAlN coating, this tool delivers consistent thread form in demanding machining environments. The cutting diameter measures 8.00 mm (0.3150 inches), matched to the 8.00 mm shank diameter for balanced setup in standard toolholders. A 0.75-inch length of cut covers typical thread depths for this thread size. Licensed machinists and CNC tool crib technicians working in precision manufacturing, aerospace, and automotive applications will recognize this as a production-grade thread milling tool.

This thread mill is suited for CNC machining centers performing internal thread milling on materials compatible with the 1630 material grade designation. The 63.00 mm (2.48 inch) overall length provides clearance for most standard spindle setups. The right-hand flute direction and 20 teeth per inch correspond directly to UNF 7/16-20 thread standards. It is applicable in shops requiring helical interpolation capability where tapping is not preferred, including blind-hole applications and materials prone to tap breakage.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard materials
• TiAlN coating for elevated heat resistance and extended tool life
• 4-flute helical design optimized for internal UNF thread milling
• Right-hand flute direction compatible with standard CNC helical interpolation cycles
• No coolant-through design — suitable for external coolant delivery setups
• 8.00 mm shank diameter fits common ER and shrink-fit toolholders

Compatibility

Designed for internal UNF thread milling at 7/16-20, 20 TPI. Intended for use in CNC machining centers capable of helical interpolation with an 8.00 mm shank toolholder. No specific machine model compatibility was provided in the product data.

Installation Notes

Installation and operation should be performed by qualified CNC machinists or tooling technicians. Ensure the spindle is fully stopped and the machine is in a safe state before installing or removing the tool from the toolholder. Confirm runout is within acceptable limits after clamping, as excessive runout will degrade thread quality and shorten tool life. Always program helical interpolation moves at the feed rates and depths of cut recommended by the tooling manufacturer for the specific workpiece material.
