Nano-Rainbow TiAlN Coated HSS-E Machine Taps | M2-M52 & UNC/UNF | High-Performance Colorful Taps for CNC
1. Introduction: The Four Pillars of Threading Excellence
Our Nano-Rainbow & TiCN Coated Series represents the next generation of tapping technology. As a factory-direct manufacturer, we have applied advanced physical vapor deposition (PVD) technology to our premium HSSE-M35 (5% Cobalt) substrate.
These coatings are not just for aesthetics—they provide a critical thermal and friction barrier. The Rainbow Nano-Coating is specifically designed for high-speed, high-heat environments, ensuring that the tool maintains its structural integrity while producing smooth, mirror-finish threads in the toughest materials.
2. Multi-Dimensional Coating Description (The Key Dimension)
| Coating Type | Appearance | Surface Hardness | Max Service Temp | Best For... |
| Nano-Rainbow (Multi-Color) | Vibrant Rainbow Gradient | 3300 - 3500 HV | 800°C | High-tensile alloys, Titanium, and Stainless Steel. Provides extreme heat resistance. |
| TiCN (Blue-Grey/Black) | Matte Grey/Black | 3000 HV | 400°C | Abrasive materials like Cast Iron, Tool Steel, and Ductile Iron. Excellent wear resistance. |
| TiAlN (Violet/Bronze) | Deep Violet/Bronze | 3300 HV | 900°C | High-speed cutting (Dry or MQL) where heat generation is massive. |
The Advantage of Nano-Rainbow Coating:
-
Ultra-Low Friction: The smooth gradient layer reduces torque and prevents "chip welding."
-
Extreme Hardness: At ~3500 HV, it is nearly 4x harder than uncoated high-speed steel.
-
Thermal Shielding: Reflects heat into the chips rather than the tool core, preventing edge softening.

4. Strategic Engineering Features
-
HSSE-M35 Substrate: The 5% Cobalt base ensures the "toughness" required to support the hard nano-coating without chipping.
-

-
Fully Ground Precision: CNC manufactured to 6H (Metric) and Class 2B/3B (Imperial) standards.
5. Material & Manufacturing Quality
-
HSSE-M35 (5% Cobalt): Provides the thermal stability required for work-hardening materials like Inox.
-
CNC Fully Ground: Every thread is ground from solid hardened steel to ensure 6H/Class 3B precision.
-
Anti-Rust Protection: Vacuum heat-treated and oiled for a 36-month shelf life.
6. Professional FAQ
Q: Why use Rainbow Coating instead of standard Gold TiN?
A: Rainbow Nano-coating offers higher surface hardness and significantly better heat resistance (up to 800°C), making it the superior choice for high-speed CNC machining in hard alloys.
Q: Can these nano-coated taps be used for hand tapping?
A: While they will work, their performance is optimized for machine tapping. The coating's benefits are most apparent at the higher speeds and temperatures found in CNC centers.
