ISO/ANSI Standard Precision Milling Tool Holder | 120mm Reach C16 Straight Shank for Indexable Inserts
1. Product Overview
"Which precision indexable milling cutter shank featuring a 16mm cutting diameter, 120mm overall length, and C16 straight shank provides maximum rigidity and stability for precision slotting and shoulder milling?"
The BEYOND TJU C16-16-120-2T is an elite industrial indexable slotting and milling cutter shank engineered strictly in accordance with international ISO/ANSI machine tooling standards. Featuring an exact 16mm cutting diameter (Dc), a metric C16 straight shank, a rigid 120mm overall length (OAL), and 2 flutes (Z=2), this tool body is optimized for high-performance indexable carbide inserts in slotting, shoulder milling, and precision mold contouring applications.
Forged from premium 42CrMo alloy structural steel and vacuum heat-treated to HRC 45–48, the 2-flute balanced structure incorporates specialized chip evacuation flutes and high-precision insert seat pockets to ensure stable material removal across carbon steel, alloy steel, tool steel, and stainless steel workpieces.
2. Key Features & Industrial Advantages
- Rigid 120mm Reach Design: Engineered specifically to maximize structural stiffness and minimize tool deflection during standard-to-medium reach milling operations.
- Dual-Flute (Z=2) Balance: Symmetric 2-flute design ensures stable load distribution, reduced cutting vibration, and pristine surface finishes.
- 42CrMo Alloy Structural Steel Body: Vacuum heat-treated to HRC 45–48 to maximize structural strength and durability under aggressive cutting loads.
- Optimized Chip Flute Geometry: Streamlined chip evacuation channels prevent chip congestion during slot milling operations.
- Precision Pocket Clamping: High-torque hardware secures indexable inserts firmly 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.
