Description
Carmex Thread Mills Mini Type - Through Coolant is a precision metric thread mill designed for small-diameter holes, delivering reliable M6 x 1 and M8 x 1 threading. Its solid carbide construction and integrated through-coolant bore optimize cutting performance in demanding applications.
- Material: Solid carbide construction for rigidity and wear resistance in threading operations.
- Coolant delivery: Internal through-coolant bore delivers high-pressure coolant through the tool into the pre-hole, washing away chips as you cut.
- Thread compatibility: Supports metric threads M6 x 1 and M8 x 1 for common applications.
- MT7 tolerance: Engineered to MT7 accuracy for consistent, repeatable thread profiles.
- Mini-type geometry: Compact flute and shank design optimized for tight holes and confined spaces.
- Pre-hole suitability: Specifically designed to operate within pre-drilled holes, enhancing chip evacuation during the threading circle.
This through-coolant thread mill excels in maintaining cutting edge temperature, improving surface finish, and extending tool life by efficiently flushing chips and reducing built-up edge. The combination of coolant through the tool and carbide rigidity supports stable, precise threads in small-diameter holes—ideal for high-precision assemblies and production environments where consistency matters.
