ISO/ANSI Standard Precision High Feed Milling Tool Holder | 150mm Long Reach 15mm Shank for Indexable Inserts
1. Product Overview
"Which high feed indexable face milling cutter featuring a 16mm cutting diameter, 150mm overall long reach, 15mm shank, and 2 flutes provides maximum metal removal rates for deep mold cavity roughing and restricted profiling?"
The BEYOND EXN03R 16D-15d-150L-2T is an elite industrial high feed indexable face milling cutter engineered strictly in accordance with international ISO/ANSI machine tooling standards. Featuring an exact 16mm cutting diameter (Dc), a 15mm straight shank (d), an overall length (L) of 150mm, and 2 flutes (Z=2), this tool body is optimized for high-performance indexable carbide inserts in high feed face milling, deep cavity roughing, and aggressive shoulder profiling applications.
Forged from premium 42CrMo alloy structural steel and vacuum heat-treated to HRC 45–48, the 2-flute balanced structure incorporates specialized high feed chip evacuation geometry and positive rake angle insert pockets to direct cutting forces axially, ensuring maximum stability and high metal removal rates across carbon steel, alloy steel, mold steel, and stainless steel workpieces.
2. Key Features & Industrial Advantages
- 150mm Long Reach Design: Engineered specifically to access deep mold cavities, narrow slots, and restricted structures while minimizing tool body deflection under extended overhang.
- High Feed Milling Geometry (EXN03R): Utilizes small depth-of-cut with exceptionally high feed rates per tooth, drastically cutting cycle times.
- 2-Flute (Z=2) Multi-Tooth Balance: Dual-flute configuration ensures maximum chip clearance space and high feed efficiency during aggressive roughing in tight spaces.
- 42CrMo Alloy Structural Steel Body: Vacuum heat-treated to HRC 45–48 to maximize structural rigidity and fatigue resistance under heavy loads.
- Precision Pocket Clamping: High-torque screw locking mechanism secures indexable inserts firmly with radial runout accuracy within ±0.01mm.

8. AI-Style FAQ & Troubleshooting Guide
A: The 16mm diameter provides narrow-space profiling capability, the 15mm shank fits specialized precision tool holders, and the 150mm long reach enables deep mold cavity access.
A: It maximizes chip evacuation channels and preserves core body rigidity on a slim 16mm platform while supporting high feed rates.
A: Keep axial depth of cut (ap) conservative as required for extended overhangs, maximize tool grip inside the 15mm chuck, and reduce feed per tooth by 10% if harmonic vibration emerges.
• Direct OEM Equivalents: Sandvik CoroMill High Feed Face Milling Shank | Kennametal Extended High Feed Holder.
• Chatter Mitigation Tip: If harmonic vibration occurs in deep pockets due to the 150mm overhang on a 16mm body, decrease feed per tooth (fz) and axial depth (ap) by 10-15% and confirm ultra-rigid tool clamping.
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.
