Verified Customer Testimonials
"Solid Reliable Grade"
We use YBC251 for 90% of our steel turning. The TCMT11 size fits perfectly in our boring bars. Great tool life.
— James T., USA 🇺🇸"Perfekt für den Preis"
Die Oberfläche ist nach dem Schlichten erstklassig. Sehr empfehlenswert für Hobby und Industrie.
— Dieter S., Germany 🇩🇪"Fast Chip Breaking"
The -52 chipbreaker really helps prevent long stringy chips on mild steel. Very happy with the results.
— Marco V., Italy 🇮🇹Expert FAQ
Q: Is YBC251 suitable for stainless steel?
A: While YBC251 can cut some ferritic stainless, we recommend the YBM series (like YBM251) for austenitic stainless (304/316) for optimal tool life.
Q: What does the -52 suffix mean?
A: The -52 refers to the chipbreaker geometry. It is specifically optimized for finishing (light depth of cut) with a sharp cutting edge to minimize work hardening.
