APKT150412-PM YBG302 ZCC.CT Milling Insert
Universal High-Toughness PVD Solution for Multi-Material Machining
Product Overview
"Looking for a single insert that reliably handles steel, stainless, and even high-temperature alloys?"
The APKT150412-PM YBG302 is the ultimate general-purpose powerhouse. Designed for the larger 15mm platform, it allows for significant depths of cut and heavy stock removal. The PM (General Purpose) geometry ensures efficient chip formation across various materials, while the 1.2mm corner radius adds substantial reinforcement to the cutting edge. The YBG302 Grade features a specialized PVD coating known for its high thermal stability and impact resistance, making it the first choice for workshops dealing with diverse material types and interrupted cutting conditions.

Product Core Advantages
- Multi-Material YBG302 Grade: Superior PVD coating that excels in steel, stainless steel, and superalloys.
- High Impact Toughness: Engineered to withstand interrupted cuts and heavy-duty milling without chipping.
- Heavy-Duty 1.2mm Radius: Larger corner radius extends tool life by distributing cutting pressure more effectively.
- PVD Thermal Shield: Resists thermal cracking, making it suitable for machining conditions where heat builds up quickly.
Application Scenarios
- Medium-duty roughing and semi-finishing of structural steel and alloy steel components.
- Effective machining of 300 and 400 series stainless steels.
- Interrupted milling where edge security is the highest priority.
- Ideal for job shops requiring a versatile insert to minimize tool inventory.

Global Verified Feedback
"YBG302 is my reliable 'go-to'. We use it on everything from standard 1045 to 316 stainless. Unbeatable toughness."
S. Miller - UK"Ottimo inserto universale. Molto resistente agli urti nelle lavorazioni interrotte."
Marco B. - Italy"The 1.2mm radius on the 15 size insert makes it very durable. Great price/performance ratio from ZCC."
G. Thompson - USATechnical FAQ
PVD coatings are thinner and can maintain a sharper edge while being more resistant to thermal shock. YBG302 is specifically designed to prevent micro-cracks from forming during the rapid heating and cooling cycles of milling.
While YBG302 can do finishing, its primary strength is stability and toughness in roughing to semi-finishing. For high-speed finishing in steel specifically, a grade like YBC301 might be faster.
Universal Machining Tip:
When using the YBG302 multi-material grade, ensure your machine setup is as rigid as possible to take advantage of the 1.2mm radius. For stainless steel, using internal coolant is recommended to flush chips and control heat, while for carbon steel, compressed air is often sufficient and helps prevent thermal shock on the PVD coating.
Technical FAQ & Buying Guide
Absolutely. Our CNC carbide inserts (including CNMG, WNMG, DNMG, and APMT series) are manufactured strictly adhering to international ISO/ANSI specifications. A CNMG 120408 from OYYU BEYOND will flawlessly fit any standard turning tool holder or indexable tool from major global brands like Sandvik Coromant, Kennametal, Iscar, Walter, or SECO, providing a highly cost-effective premium alternative without sacrificing tolerance or tool life.
We offer optimized CVD and PVD multi-layer coatings for different ISO material groups:
- For Carbon/Alloy Steel (ISO P): Choose our thick multi-layer CVD coated grades (e.g., Al2O3 + TiN). They provide exceptional crater wear resistance and thermal barriers during high-speed dry or wet roughing.
- For Stainless Steel (ISO M): Choose our nano-structured PVD coated grades with sharp, positive chipbreakers (like -TM or -MA). This combination prevents work hardening and effectively controls sticky chips.
The optimal cutting parameters vary depending on the workpiece hardness and operation type:
- For General Steel Turnings: Recommended cutting speed ($V_c$) ranges from 150 to 280 m/min, with a feed rate ($f$) of 0.15 to 0.45 mm/rev.
- For Stainless Steel Finishing: Recommended cutting speed ($V_c$) is 120 to 200 m/min, with a feed rate ($f$) of 0.10 to 0.25 mm/rev.Always adjust parameters based on early wear patterns: increase $V_c$ if built-up edge occurs, or reduce $V_c$ if severe flank wear is observed.
