Features
Chipless Cold Roll Forming: Forms high-strength internal threads by plastic deformation without producing metal swarf or chips.
30-50% Higher Pull-Out Strength: Preserves unbroken metal grain fibers within the extruded boss for superior torque resistance.
Wear-Resistant TiN/TiAlN Coating: Low-friction surface coating prevents material adhesion and extends tap life in tough metals.
Precision 6H Metric Tolerance: Consistently delivers smooth, accurate, burr-free thread profiles across high-volume runs.

Executive Overview
DUOMI CNC offers heavy-duty, high-precision CNC metal tapping bits engineered for rigorous industrial thread cutting across ferrous and non-ferrous metals. Designed to integrate seamlessly with automated CNC drilling and tapping centers, our metalworking & multipurpose drill bits deliver exceptional wear resistance, minimal chip loading, and high-pitch accuracy under continuous production demands.
Key Features & Technical Capabilities
- Multi-Metal Versatility: Engineered specifically for multiple metal tapping operations across soft alloys, tough steels, and exotic non-ferrous materials.
- Precision Threading Accuracy: Meets strict ISO/DIN thread tolerances (H2/H3 compliance) ensuring high repeatability across long manufacturing runs.
- Optimized Chip Flute Design: Advanced spiral flute geometry rapidly clears swarf, reducing torque build-up and preventing tap breakage during blind-hole tapping.
- High-Durability Tool Coatings: Optional TiN, TiAlN, or DLC heat-resistant coatings enhance surface hardness up to 3000 HV and double tool service life.
- OEM & Non-Standard Customization: Available in customized pitch, diameter, and shank configurations to fit specialized CNC machinery setups.
Compatible Materials & Industry Applications
Our industrial multipurpose drill and tapping bits excel in high-torque metalworking applications processing: - Structural & Ferrous Metals: Iron, Carbon Steel, Stainless Steel, Die Steel - Non-Ferrous Alloys: Aluminum, Brass, Copper, Zinc Alloy, Cast Bronze - Precious & Specialty Metals: Platinum, Titanium alloys, and engineered metals
Primary Industry Sectors
- Automotive & Aerospace: Engine block thread tapping, structural bracket fastening.
- Precision Electronics & Enclosures: Aluminum housing thread forming and heat-sink machining.
- General CNC Manufacturing: Mass-production thread cutting for heavy machinery components.
Industrial Advantages & ROI Impact
- 50% Tool Wear Reduction: Micro-grain carbide and HSS-Co matrix extend tool life under high SFM (Surface Feet per Minute).
- High Throughput Speeds: Optimized for high-RPM synchronous rigid tapping operations up to 3,000 RPM.
- Reduced Line Downtime: Consistent tap geometry minimizes machine stoppages caused by tap binding or tool fracture.
