High Hardness Steel Thread Mill Solid Carbide Metric Thread Milling Cutter for Blind & Through Hole
Bullet Points
Super Toughness & Durability:Made of ultra-fine grain solid carbide, it has significantly higher toughness and wear resistance than standard taps. It adapts to interrupted steel cutting without easy chipping or fracture, ensuring extremely stable machining performance.
Advanced Wear-resistant Coating:Equipped with premium TiAlN/AlCrN coating, featuring high temperature resistance, oxidation resistance and wear resistance. It is suitable for heavy cutting of high-hardness steel, greatly extending tool life and reducing frequent tool replacement costs.
Optimized Flute Geometry:Optimized helical and straight flute design reduces cutting load and avoids chip clogging. It is applicable to both through holes and blind holes with high thread forming accuracy and smooth surface finish.
Applications
Aerospace Components:Ideal for thread machining of high-strength alloy components such as landing gear and turbine parts, maintaining stable cutting and lasting precision under high-stress working conditions.
Mold & Die Making:Specially designed for heat-treated high-hardness tool steels of injection molds and stamping dies, suitable for long-term batch processing with low tool loss.
Hot Q&A
Why choose thread mill over tap for high-hardness steel?
Thread mills generate lower cutting heat and fundamentally avoid chipping and breakage risks. Meanwhile, one tool fits multiple thread specifications with stronger versatility, delivering far better comprehensive efficiency and cost performance than traditional taps.
Optimal cutting speed for HRC50+ steel?
The standard recommended cutting speed is 60–80 SFM (18–24 m/min) with moderate feed rate. Parameters can be fine-tuned according to coating type and coolant working conditions.
Can it handle interrupted cuts on tough steel?
Yes. The tool features high overall rigidity and impact-resistant wear coating, which perfectly adapts to unstable interrupted cutting scenarios with performance far superior to brittle taps.
