Three Functions in One Tool
Single-Step Operation: Integrates drilling, chamfering, and tapping, reducing cycle time by 60%.
High Concentricity: Coaxial design ensures alignment between hole and thread (≤0.02mm deviation).
Material & Coating Technology
HSS-E or Carbide: Hardness up to 65-68 HRC, suitable for hardened steel and stainless steel.
TiN/TiCN Coating: Heat resistance (1000ºC+) and wear resistance, triple tool life.
DIN Standard Precision
DIN Compliance: Thread tolerance class 6H, hole diameter accuracy ≤±0.05mm.
Metric Thread Range: Compatible with DIN standard threads (M3-M12).
Efficient Chip Evacuation
Spiral Flute Design: Optimized chip flow in both drilling and tapping sections, ideal for aluminum and copper.
Multi-Environment Adaptability
Dry/Wet Cutting: Supports dry machining (carbide tools) or MQL lubrication.
