Description
Carmex’s Through-Coolant Thread Mill is a carbide tool engineered for precision threading in through-holes. Designed for shops that need reliable imperial threads (UNC, UNF, UNEF, UNS) with a versatile MT7 shank, it delivers coolant directly to the cutting edge for smoother, more efficient machining.
- Material: Carbide construction for rigidity and wear resistance in demanding threading operations.
- Coolant delivery: Through-coolant design routes coolant through the flutes directly to the cutting edge, improving heat management and chip control.
- Thread forms: Compatible with UNC, UNF, UNEF, and UNS threading standards for versatile applications.
- Size and interface: 9/16" diameter with 12 TPI thread pitch; MT7 shank fits a wide range of CNC machines.
- Application: Optimized for threading through-holes with direct chip evacuation to minimize clogging and re-cutting.
- Machine compatibility: Effective even on setups without external coolant systems, expanding where you can reliably thread.
This tool excels in bring-your-own-coolant setups, delivering consistent thread quality on through-holes and enabling longer tool life through effective heat dissipation. It’s well-suited for manufacturing environments that require durable threading in metal components such as housings, fixtures, and assemblies where through-holes are common. Expect clean thread profiles, reduced cycle times, and reliable performance across a range of materials thanks to its robust carbide core and integrated coolant delivery.
