What is a Coated Drill Bit?
A coated drill bit is a cutting-edge drilling tool featuring advanced surface coatings (Titanium Nitride, Titanium Aluminum Nitride, or Tungsten Carbide) designed to enhance performance in demanding applications. Key benefits include:
- Extended Tool Life: Coatings reduce wear by up to 70% compared to uncoated bits
- Optimized Drilling Efficiency: Lower friction cuts energy consumption by 25-40%
- Thermal Stability: Withstands temperatures up to 800°C (1,472°F)
- Superior Chip Evacuation: Micro-groove design prevents chip packing in deep holes
Industries relying on coated drill bits include aerospace component manufacturing, automotive engine machining, and heavy-duty construction projects.
Key Features of Coated Drill Bits
1 300% Longer Service Life
- Titanium-based coatings (TiN/TiAlN) resist deformation in high-speed applications
- Tungsten Carbide (WC-Co) variants excel in abrasive materials like cast iron
2 40% Faster Cutting Speeds
- Reduced cutting forces allow higher feed rates without compromising precision

Selection Guide：
1 Material-Specific Coatings
➤ TiN Coating: Ideal for aluminum/steel (≤50 HRC)
➤ TiAlN Coating: For stainless steel/titanium (50-60 HRC)
➤ WC-Co Coating: Required for hardened steels (>60 HRC)
2 Depth & Diameter Matching
- Shallow Holes (≤5xD): Standard flute design
- Deep Holes (>5xD): Parabolic flutes for better chip evacuation
3 Machine Compatibility
- CNC Machines: Require balanced tools (≤0.003mm runout)
- Handheld Drills: Use reduced-shank designs for stability
