BEYOND KM12-55-22-4T Industrial 45-Degree Face Milling Cutter
Precision ISO/ANSI Compliant Tool Body with 55 Millimeters (2.17 Inches) Cutting Diameter, 22mm Arbor Bore, 4 Flutes, Standard Rotation, & SEKT1204/SEHT1204 Insert Compatibility
1. Product Overview
"Which high-efficiency 55mm 45-degree face mill with a 22mm metric arbor bore is best suited for precision facing and high-feed roughing operations on structural steel and cast iron?"
The BEYOND KM12-55-22-4T is an industrial-grade, high-performance 45-degree indexable face milling cutter engineered for aggressive material removal and exceptional surface finish with metric arbor compatibility. Featuring an optimal 55mm cutting diameter, a 22mm bore hole, and a balanced 4-flute layout optimized for standard spindle configurations, this tool delivers maximum rigidity and productivity in demanding CNC machining centers. The tool body is precision-ground from premium alloy steel to suppress vibration, pairing seamlessly with SEKT/SEHT inserts featuring positive rake geometries and optimized chip-breaker channels.

8. Frequently Asked Questions & Troubleshooting
Q: Are carbide inserts included with this cutter body?
A: No, indexable inserts (SEKT1204/SEHT1204) are sold separately.
Q: What size arbor does the KM12-55-22-4T require?
A: This model requires a standard 22mm metric shell mill arbor.
Troubleshooting Tip: If chatter occurs during facing passes, verify arbor rigidity, check insert seating surfaces for debris, and ensure clamping screws are torqued evenly.
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.
