Solid Carbide Pointed Tap for Aluminum Alloy CNC Machining Through Hole Threading Tool
Bullet Points
3× Longer Tool Life: Solid carbide withstands 70% higher cutting speed than HSS taps, reducing replacement cost.
Superior Surface Finish: Polished flutes & sharp cutting edges achieve Ra＜1.6μm, no secondary rework.
Anti-Breakage Design: Reinforced shank & fracture-resistant carbide grade tolerate misalignment.
Anti-BUE Technology: TiAlN coating reduces friction by 40%, preventing built-up edge on gummy aluminum.
Efficient Chip Evacuation: 45° helix enables downward chip removal, no tangling on shank.
Applications
Aerospace Components: Precision threading of 7075-T6 aluminum bulkheads, landing gear parts, engine housings.
Automotive Manufacturing: High-volume production of EV battery trays, transmission cases, suspension components.
Die-Cast Electronics: Clean threading in smartphone frames, heatsinks, 5G antenna enclosures (no tap seizure).
Hot Q&A
- Why choose carbide over cobalt HSS for aluminum?
Answer: Carbide maintains edge sharpness 5x longer than HSS in Si-rich alloys (e.g., A380), preventing thread galling and ensuring consistent quality.
- What coolant is recommended?
Answer: Use non-chlorinated synthetic coolants (7-10% concentration). Never run dry – carbide’s brittleness requires lubrication to prevent thermal shock.
- How to optimize feed rate and cutting speed?
Answer: Start at 25-35 SFM (7.6-10.7 m/min) with 0.8-1.2 mm/rev feed. Increase incrementally for AlSi alloys (up to 150+ SFM with flood coolant).
