BEYOND R2.5 (5mm) Steel Chamfer End Mill – Arc Type Up & Down Chamfer Cutter
The BEYOND R2.5 (5mm) Steel Chamfer End Mill is engineered for high-precision chamfering and deburring of steel materials. Its unique arc-shaped cutting edges allow for both upper and lower chamfering, providing smoother transitions and superior surface finishes in CNC machining applications.
Key Features
- Material: Ultra-fine tungsten carbide for excellent wear resistance.
- Design: Arc-type geometry supports both up & down chamfering operations.
- Chamfer Radius (R): R2.5 (cutting diameter 5mm).
- Application: Ideal for carbon steel, alloy steel, die steel, and pre-hardened steel.
- Coating: TiAlN or AlTiN coating for enhanced heat resistance and extended life.
- Shank: Precision-ground 5mm shank for perfect tool balance.
- Machine Compatibility: Suitable for CNC milling centers, engraving machines, and high-speed spindles.

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.
