BEYOND EMR4R-16-150-C16-2T Indexable Milling Cutter Shank
ISO/ANSI Standard 16mm Face Milling Tool Holder | Medium-Reach C16 Straight Shank (150mm OAL) for RPMW0802/RPMT0802 Inserts
1. Product Overview
"Which 16mm indexable milling cutter shank with a 150mm overall length and C16 straight shank provides balanced rigidity and clearance for RPMW0802/RPMT0802 inserts?"
The BEYOND EMR4R-16-150-C16-2T is an industrial-grade, medium-long-reach indexable face milling cutter shank engineered in strict compliance with international ISO/ANSI machine tooling standards. Featuring a 16mm cutting diameter (Dc), a 16mm straight shank (C16), a 150mm overall length (OAL), and 2 flutes (Z=2), this tool body is optimized for positive-rake 08-series round carbide inserts (RPMW0802 / RPMT0802).
Forged from high-grade 42CrMo alloy structural steel and vacuum heat-treated to HRC 45–48, the 2-flute architecture incorporates precision chip pockets to facilitate smooth evacuation in moderate-depth mold cavities and restricted routing paths. The circular geometry distributes cutting forces evenly, minimizing harmonic vibration and tool deflection across carbon steel, alloy steel, and stainless steel applications.
2. Key Features & Industrial Advantages
- Balanced 150mm Overhang Reach: Engineered to provide an optimal balance between structural rigidity and cavity clearance for medium-depth profiling.
- Optimized 2-Flute Configuration: Streamlined chip channels ensure efficient evacuation and prevent thermal overload during heavy feed passes.
- 42CrMo Alloy Structural Steel Body: Precision heat-treated to HRC 45–48 to deliver high torsional stiffness and fracture resistance.
- Anti-Corrosive Surface Passivation: Special chemical treatment reduces friction coefficient and prevents built-up edge (BUE).
- Precision Screw-Lock Clamping: M2.5 Torx clamping hardware secures indexable inserts tightly with radial runout accuracy within ±0.01mm.

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.
