Learn more about Klarna
The Carmex Thread Mills Carbide—Single Point Through Coolant is a precision threading tool designed for both internal and external threads, built for reliability in demanding metalworking environments. With a 60-degree partial-profile and a through-coolant design, it delivers consistent cuts and extended tool life in a compact footprint, ideal for workshop and production settings.
- Through-Coolant: Internal coolant delivered through the flutes cools the cutting edges and evacuates chips for cleaner finishes and longer tool life.
- Profile: 60° partial-profile optimized for deep or constrained threading where full-profile tools can’t reach.
- Threading Capability: Supports both internal and external threads, reducing tool changes and expanding job options.
- Pitch Range: Internal threads down to 0.5 mm pitch and external threads down to 0.4 mm pitch for versatile applications.
- Depth Capability: Capable of cutting threads up to 50 mm deep, enabling long-thread runs in a single pass.
- Flutes & Coating: 4–5 flutes on a carbide body with MT8 sub-micron grade and an advanced PVD triple coating (ISO K10–K20) for superior wear resistance and heat tolerance.
- Shank: MT11 shank provides solid compatibility with standard tool holders and high-precision setups.
- Materials Versatility: General-purpose threading tool designed to perform reliably across a wide range of metals and alloys.
The through-coolant design minimizes chip buildup and overheating, delivering smooth, stable cuts and helping preserve surface quality on threaded features. Its 60° partial profile enables clean threads in tight cavities, while the dual capability to machine both internal and external threads makes it a flexible choice for complex assemblies. With a robust carbide core and advanced coating, this tool maintains cutting performance across metals—from plastics-leaning alloys to harder steels—making it a dependable option for aerospace, automotive, mold & die, and general manufacturing applications. The long 50 mm depth capacity supports efficient, single-pass threading workflows, reducing cycle times and improving throughput.
