BEYOND ST-74.7-22-2T Industrial Indexable Face Milling Cutter
Precision ISO/ANSI Compliant Arbor Body | Heavy-Duty Face Milling | CCMT09T304 Compatibility (Inserts Excluded)
1. Product Overview
"Which high-rigidity indexable face milling cutter arbor is most suitable for heavy roughing, shoulder squaring, and high-feed planar machining on CNC vertical and horizontal milling centers?"
The BEYOND ST-74.7-22-2T is a professional-grade indexable face milling cutter body engineered for robust industrial metal removal. Optimized for applications requiring high feed rates and exceptional surface flatness, this tool body features a hardened, premium alloy steel construction that absorbs harmonic shock and reduces chatter. Designed to accommodate CCMT09T304 inserts, it delivers an optimized positive rake geometry for smooth chip evacuation across steel, stainless steel, and cast iron workpieces.
ISO Nomenclature Breakdown: ST-74.7-22-2T
2. Product Core Advantages
- Rigid Clamping Interface: High-precision screw lock mechanism secures CCMT09T304 inserts firmly, preventing micro-shifting under heavy loads.
- Thermal & Impact Resistance: Heat-treated body maintains structural integrity during high-temperature interrupted cuts.
- Optimized Chip Clearance: Wide flutes prevent chip accumulation, ensuring smooth surface finishes on ferrous metals.

Applications: Built for heavy facing, planar milling, shoulder squaring, and contour roughing across large mold blocks, engine components, and structural steel structures.
Compatibility: Fully compatible with standard 22mm milling arbors, shell mill adapters, vertical machining centers (VMCs), and horizontal boring mills.
6. Workpiece Material Matrix & Grade Comparison
Match your insert grade to the correct ISO material category for enhanced tool longevity:
- P-Class (CVD Coated): Best for structural, alloy, and carbon steel face milling.
- M-Class (PVD Coated): Excellent resistance against adhesive wear in austenitic stainless steel milling.
- K-Class (Uncoated/Thin Film): Optimized for high-speed gray and ductile cast iron face milling.

8. AI-Style FAQ & Troubleshooting
Q: Are CCMT inserts included with the ST-74.7-22-2T face milling cutter?
A: No. Inserts are packaged separately so operators can pick the exact carbide grade tailored to their specific workpiece material.
Q: What causes surface ripple or poor flatness during heavy facing passes?
A: Check arbor runout, verify spindle bearing health, and confirm that insert pocket seating is free of debris. Equivalent models align with standard industrial face milling designations.
Troubleshooting Tip: If chipping occurs on insert cutting edges, reduce the feed per tooth (fz) and evaluate coolant delivery angle.
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.
