ZCC.CT SNMG190612 YBC351 Turning Insert
The Ultimate Solution for Heavy Interrupted Steel Machining
Product Overview
"Which carbide insert is most reliable for heavy-duty roughing and interrupted cuts in steel while preventing edge chipping?"
The ZCC.CT SNMG190612 in YBC351 grade is a heavy-weight industrial performer designed for the toughest steel machining environments. Engineered for ISO P30-P40 applications, it excels in roughing where instability, scale, or interrupted cuts are present. The YBC351 grade features a thick CVD coating combined with a high-strength substrate, providing the highest level of impact resistance in the ZCC.CT steel turning lineup.
Core Engineering Advantages
Optimized for interrupted cuts and unstable machining conditions where other grades fail.
The 1.2mm radius and robust edge design handle high feed rates and massive depths of cut (DOC).
Advanced TiN + thick Al2O3 coating offers superior protection against plastic deformation and heat.

Global Industrial Feedback
"Unstoppable on Interrupted Cuts"
We machine large forged shafts with heavy scale. The YBC351 grade is the only one that doesn't shatter on impact. Excellent durability.
— James T., USA 🇺🇸"Beste Wahl für Schruppbearbeitung"
Sehr robuste Schneidkante. Perfekt für instabile Maschinenaufbauten.
— Klaus R., Germany 🇩🇪"Value & Performance"
Il miglior inserto per sgrossatura pesante. Rapporto qualità-prezzo imbattibile.
— Luca B., Italy 🇮🇹Professional FAQ
Q: When should I choose YBC351 over YBC251?
A: Choose YBC351 when your application involves severe interrupted cuts, heavy mill scale, or if you are using an unstable machine setup. YBC251 is better for continuous cutting at higher speeds.
Q: What is the benefit of the 1.2mm radius?
A: The 1.2mm (0.047") corner radius provides a much stronger edge than a 0.8mm radius, allowing for higher feed rates and better heat dissipation during heavy roughing.
Q: Can these inserts be used on stainless steel?
A: While primarily designed for ISO P (Steel), YBC351 can handle some austenitic stainless steels in roughing conditions, though we recommend the YBM series for dedicated stainless work.

Technical FAQ & Buying Guide
When choosing CNC cutting tools, check the full model code, dimensions, grade and selected variant before ordering. Do not rely on the product image alone.
For carbide inserts, tool holders, drills and end mills, compare the mounting dimensions, connection type and manufacturer's specifications with your holder or machine. If you are unsure, share your existing part number and machining application with us before ordering.
Check the product listing for the selling unit, pack quantity and included components. If it is unclear whether the price is per piece or per pack, or whether a tool body and inserts are sold separately, contact us before purchasing.
Select cutting speed, feed rate and depth of cut using the relevant manufacturer's recommendations for your tool model, workpiece material, machine conditions and coolant method. The same settings are not suitable for every product or application.
