Conquer Challenging Materials with Unmatched Durability
Engineered for extreme conditions, our Interrupted Thread Tap specializes in threading porous castings, welded joints, and uneven surfaces where standard taps fail. Featuring reinforced carbide construction and patented flute geometry, it eliminates chipping and breakage during interrupted cuts - ideal for automotive, foundry, and heavy equipment manufacturing.
1. Unbreakable Performance
Asymmetric Flute Design: Absorbs lateral forces during entry/exit from gaps (e.g., keyways, cross-holes).
Shock-Resistant Carbide Core: 5× higher fracture toughness vs. HSS taps (Grade K30F).
2. Precision Thread Integrity
Variable Pitch Relief: Maintains ±0.02mm pitch accuracy in cast iron (GG25), ductile iron, and sintered metals.
Full-profile threads conform to ISO 68°, UNJ, and NPT standards.
3. Optimized Chip Evacuation
Spiral Point (Gun Nose): Directs chips forward in blind holes.
Polished Flutes: Prevents chip welding in sticky alloys like aluminum.
4. Cost-Saving Longevity
Hybrid TiAlN+AlCrN Coating: Reduces friction by 40% and withstands 1,200°C for 10,000+ holes in cast iron.
Regrindable up to 3 times (supported by OEM service).
