ZCC-CT CNMG120404-04 YBG302 – Turning Carbide Insert

ZCC.CT CNMG120404-EM YBG302: Specialized Stainless Steel Machining Product Overview “Which carbide turning insert provides the best reliability for medium machining of stainless steel and heat-resistant alloys under unstable conditions?” The ZCC.CT CNMG120404-EM YBG302 is a versatile powerhouse engineered for the M-group (Stainless Steel) and S-group (Superalloys). The YBG302 grade features an advanced PVD coating (TiAlN) over a tough, fine-grained substrate, offering an excellent balance of wear resistance and impact toughness. The EM chipbreaker is specifically designed for medium turning operations, providing a sharp cutting edge that minimizes work hardening while maintaining enough strength to handle slight interruptions and varying depths of cut. Key Features Advanced YBG302 PVD Coating: Optimized for thermo-chemical stability and resistance to notched wear. EM Medium-Duty Geometry: Features a sharp edge and wide chip-breaking range to prevent chip entanglement. Double-Sided Design: 8 usable cutting edges (4 per side) maximize cost-efficiency for industrial production. High Toughness: Excellent performance in interrupted cuts and machining with scale or skin.

The YBG302 held up much better than our previous brand against notched wear. Highly recommend for difficult materials.” — Mark T., USA ★★★★★ “Excellent Chip Control” “The EM chipbreaker is the best we’ve used for 316 stainless. No more stringy chips wrapping around the spindle.” — Dieter H., Germany ★★★★☆ “Great for manual lathes too” “Stable performance in Italy shop. Even on older lathes where rigidity isn’t perfect, these don’t chip easily.” — Giovanni F., Italy Frequently Asked Questions Q: Is the YBG302 grade better than CVD grades for stainless steel? A: PVD grades like YBG302 are generally superior for interrupted cuts and unstable conditions due to higher toughness and a thinner, sharper edge compared to CVD. Q: What is the optimal depth of cut for the EM chipbreaker? A: The EM geometry is optimized for medium machining, typically performing best at depths of cut (ap) between 1.0mm and 4.0mm. Q: Can these be used for steel machining? A: While optimized for stainless (M), YBG302 is a “universal” grade that performs well in carbon and alloy steels, especially in smaller shops needing versatility. Industrial Tip: To extend tool life in stainless steel finishing, ensure high-pressure coolant is directed exactly at the cutting edge to prevent work-hardening.

Grade YBG302 Characteristics

ZCC-CT YBG302 uses PVD coating tuned for finish machining on steel, stainless steel, cast iron. The chemistry favors edge stability under interrupted cutting and resists thermal cracking on longer passes.

Features & Benefits

100% Genuine ZCC-CT – Original product with full quality guarantee, traceable batch.
Professional CNC Tooling – Compatible with major CNC machine brands (Mazak, DMG, Haas, Doosan).
PVD Coating – Superior wear resistance and extended tool life under continuous load.
Thermal Resistance – pvd layer holds hardness above typical cutting-zone temperatures.
Edge Stability – Substrate chemistry tuned to limit micro-chipping on steel, stainless steel, cast iron interruptions.
Optimized Chip Breaker – Engineered chip geometry reduces re-cutting and machine downtime.

Recommended Applications

Finish Machining of steel, stainless steel, cast iron in production CNC lines
Suitable for both wet and dry machining conditions
Effective in interrupted and continuous cutting passes
CNC lathe and machining center compatible

Buying Considerations

Single-pack option — useful for prototype runs or qualification before bulk commitment. Mid-tier pricing reflects ZCC-CT’s production-grade tolerances rather than economy substrate.

Tip: Match this insert to a holder whose seat matches the ISO designation. If you’re unsure, send us the holder model and we’ll confirm compatibility before shipping.
