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.

Industrial Overview
DUOMI CNC delivers high-performance tapping bits and metalworking drill bits engineered to meet the rigorous demands of modern automated production lines. Designed for precision threading across ferrying, non-ferrous, and precious metals, these tools ensure clean thread geometry, minimum burr formation, and extended tool life under high-duty cycle operations.
Whether integrated into automatic tapping machines, multi-axis machining centers, or custom CNC units, our multipurpose drill and tapping bits optimize machining throughput while reducing overall tooling operational costs.
Key Features & Technical Advantages
- Superior Thread Accuracy: Engineered to achieve precise pitch standards with tolerances within ±0.02mm.
- Optimized Chip Evacuation: Spiral and straight-flute geometries prevent chip clogging, ensuring consistent blind and through-hole tapping.
- Extended Tool Life: Special heat treatment and wear-resistant coatings enhance thermal stability, reducing tool wear by up to 35% compared to standard carbon steel bits.
- Multipurpose Metalworking Capabilities: Capable of single-pass drilling and tapping operations across diverse alloy hardness levels.
- High Machining Efficiency: Operates seamlessly at spindle speeds up to 3,000 RPM depending on target material tensile strength.
