BEYOND 22ER 6.0 TR BY18A Threading Insert
High-Performance PVD Nano-Coating | Universal Grade for Stainless & Steel
How does PVD coating improve 6mm pitch trapezoidal threading?
The BEYOND 22ER 6.0 TR BY18A is an industrial-grade external threading insert engineered for heavy-duty Trapezoidal (TR) DIN 103 profiles. The core advantage lies in its BY18A Nano-PVD coating, which offers a technical performance profile similar to the industry-leading Mitsubishi VP15TF. This physical vapor deposition process allows for a thinner, tougher, and significantly sharper cutting edge compared to CVD coatings. With a large 22mm IC and a 6.0mm pitch capability, this insert is optimized for machining tough materials like 300-series stainless steel, carbon steel, and heat-resistant alloys where edge integrity and thermal stability are critical.
BY18A PVD Technology
A multi-layered AlTiN-based PVD coating that provides high surface hardness (HV3000+) while maintaining a sharp cutting edge, effectively preventing Built-Up Edge (BUE) in gummy materials.
Heavy-Duty TR 6.0 Profile
Precision-ground full profile geometry ensures consistent 30° thread angles and peak-to-root accuracy, meeting strict DIN 103 B2B quality standards.
Excellent Thermal Shield
The PVD layer acts as a powerful thermal barrier, protecting the micro-grain carbide substrate during the high-friction environment of large-pitch threading.

Reviews from Professional Workshops
⭐⭐⭐⭐⭐ "Excellent PVD Quality" - Markus R., Germany
"The BY18A grade works almost exactly like the VP15TF we used to use. Very stable for large TR threads in stainless steel."
⭐⭐⭐⭐⭐ "Perfect for Stainless" - James D., USA
"Threading 316 stainless with a 6mm pitch is a nightmare, but these inserts hold up. No chipping even after 20 pieces."
⭐⭐⭐⭐⭐ "Sharp and Clean" - Luca V., Italy
"The thread profile is incredibly sharp. We are getting a mirror finish on the flanks of the TR lead screws."
⭐⭐⭐⭐⭐ "Top B2B Value" - Hiroshi T., Japan
"Consistent quality across multiple boxes. We use these for our high-precision valve stems."
⭐⭐⭐⭐⭐ "Very Tough" - Pavel S., Poland
"Industrial grade is real. These handled interrupted cuts on alloy steel with ease. Highly recommended."
8. FAQ - Professional Engineering Support
Q: Is the BY18A grade better for stainless than CVD grades?
A: Yes. Because PVD is thinner and keeps the cutting edge sharper, it prevents the "rubbing" and work-hardening common when using CVD on stainless steel.
Q: How should I set the infeed for a 6.0 pitch?
A: For such a large pitch, we recommend a modified flank infeed (1-3 degrees) to ensure chips only form on one side of the edge, reducing stress on the tip.
Q: Can I use this for TR 6.0 ACME threads?
A: No. While they look similar, TR uses a 30° angle and ACME uses 29°. Using the wrong insert will result in a thread that does not fit its mating part.
Industrial Tip: The PVD Edge
For the best results with **BY18A**, treat it like a premium **VP15TF**. High cutting speeds and consistent coolant flow are your friends. The sharpness of the **Nano-PVD** layer is your greatest weapon against thread chatter. **BEYOND CNC** - The Science of Cutting.
