APKT150412-HT YBG202 ZCC.CT Milling Insert
High-Efficiency Universal Roughing for Steel & Stainless Steel
Product Overview
"Looking for a reliable roughing insert that handles both alloy steel and stainless steel with a perfect surface finish?"
The APKT150412-HT YBG202 is a multi-purpose 90° shoulder milling insert. The HT chipbreaker is specifically engineered with a reinforced negative land to prevent edge collapse during heavy-duty roughing. Coupled with the YBG202 Grade—a nano-structured TiAlN PVD coating—it provides a smooth cutting action and excellent wear resistance in ISO P (Steel), ISO M (Stainless Steel), and even ISO S (Superalloys).

Global Verified Reviews
"YBG202 is my favorite grade. It works on almost everything in my shop. The HT chipbreaker makes roughing 304 stainless much easier."
Steve H. - USA"Sehr zuverlässige Wendeschneidplatte. Gute Standzeit in legiertem Stahl."
Andreas W. - Germany"Ottima per sgrossatura. Resistenza all'usura molto alta. Spedizione veloce."
Luca M. - Italy"汎用性が高く、コストパフォーマンスが素晴らしい。ステンレス鋼でも安定して使えます。"
Hiroshi K. - Japan"Standard ZCC quality. Never failed me in 10 years of machining."
David G. - UKTechnical FAQ
It depends on the goal. YBG202 is harder and better for finishing or medium cutting at higher speeds. YBG302 is tougher and better for heavy interrupted cuts or vibration-prone setups.
While the HT chipbreaker is designed for Roughing, the YBG202 grade provides a very clean finish. For precision finishing, consider the -PM or -EM geometries.
Every box of ZCC.CT inserts we sell contains a factory label with a unique QR code and serial number for global verification.
Machining Efficiency Tip:
To maximize the tool life of YBG202 in stainless steel, maintain a steady feed rate to prevent work hardening. If you observe Built-Up Edge (BUE), increase your cutting speed (Vc) slightly to generate enough heat for the chip to flow smoothly.
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.
