Bullet Points

Super High Rigidity Straight Flute Design : Straight flute structure delivers stronger rigidity than spiral flute cutters, stable cutting for HRC45–65 hardened steel and cast iron, outstanding performance under interrupted cutting.

Smooth Chip Evacuation & Burr-Free Thread Surface : Linear straight flute channels rapidly discharge iron scraps to avoid workpiece scratching, forming clean threads without secondary deburring process.

Long Service Life with TiAlN Nano Coating : Multi-layer TiAlN coating reduces friction and heat accumulation, effectively prevent thermal cracking, tool life is 50% longer than ordinary thread mills.

High Efficiency One-Pass Integrated Machining : Skip pre-drilling bottom hole, realize drilling and threading synchronously, single rotation completes thread forming to boost mass production efficiency.

Shock & Wear Resistant Reinforced Cutting Edge: Reinforced cutting edge and anti-vibration geometry, adapt to intermittent cutting of mold, aerospace and oil-gas workpieces.

Wide Equipment & Thread Compatibility: Fits all CNC milling machines, supports full range metric thread sizes and pitches, capable of both internal and external thread processing.

Applications

Mold & Die Manufacturing: Process high-stress injection molds, stamping dies, produce precise durable threads for hard mold steel and cast iron mold bases.

Aerospace Components : Thread machining for landing gear fittings, engine mounts, meets strict precision requirements of hardened aviation steel parts.

Oil & Gas Industry: Machining drill collars, valves, downhole equipment, anti-abrasion cutting for high-strength alloy and cast iron workpieces.

General CNC Machining: Mass production of auto parts, mechanical fixtures, cast iron hardware, stable consistent thread batch processing.

Hot Q&A

Can this straight flute thread mill handle interrupted cuts on cast iron and hardened steel?

Answer: Yes. Reinforced cutting edge and shock-resistant geometry adapt well to intermittent cutting, not easy to chip or break.

What’s the difference between straight flute and spiral flute thread mill?

Answer: Straight flute has higher rigidity for hard materials (cast iron, HRC45–65 steel); spiral flute is more suitable for soft metals like aluminum and copper. Select according to workpiece hardness.
