Deep Hole Series Thread Milling Tools

Deep hole series thread milling tools are made from ultra-fine grain carbide substrate with a specialized PVD coating, optimized for the demanding conditions of deep hole threading. The tool features an extended design with a reinforced core and unique internal coolant channels, effectively addressing chip evacuation and vibration challenges in deep holes. With precisely ground thread profiles and strict dynamic balance control, these tools reliably produce high-precision threads for M8-M42 sizes in holes with depth-to-diameter ratios ≥ 3D. Excellent vibration resistance and reliable cutting performance can increase deep hole threading efficiency by over

● Optimized for Deep Holes: Large length-to-diameter ratio design, supports threading up to 5D deep holes, ensuring machining stability.
● Superior Chip Evacuation: Internal coolant channels combined with an optimized groove design enable efficient chip removal in deep holes.
● Excellent Rigidity: Reinforced core structure and specially treated extended shank effectively suppress vibration during deep hole machining.

● Reliable Machining Accuracy: Precisely ground thread profile ensures dimensional accuracy and high surface quality of threads in deep holes.

● Energy Industry: Threading deep hole components in energy equipment manufacturing.
● Automotive Manufacturing: Threading deep holes in engine blocks, transmission cases, etc.
● Mold Manufacturing: Threading deep cooling channels in injection molds, die-casting molds, etc.
