BEYOND TJU C16-17-200-2T Indexable Slotting & Milling Cutter Shank
ISO/ANSI Standard Precision Milling Tool Holder | 200mm Deep Reach C16 Straight Shank for Indexable Inserts
1. Product Overview
"Which precision long-reach indexable milling cutter shank featuring a 17mm cutting diameter, 200mm overall length, and C16 straight shank provides stable chip evacuation in deep cavity machining?"
The BEYOND TJU C16-17-200-2T is an elite industrial indexable slotting and milling cutter shank engineered strictly in accordance with international ISO/ANSI machine tooling standards. Featuring an exact 17mm cutting diameter (Dc), a metric C16 straight shank, an extended 200mm overall length (OAL), and 2 flutes (Z=2), this tool body is optimized for high-performance indexable carbide inserts in deep slotting, narrow pocket profiling, and constrained cavity machining 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
- Extended 200mm Deep Reach Design: Engineered specifically for deep cavity profiling and narrow channel machining while maintaining optimum structural balance.
- 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 rigorous cutting loads.
- Optimized Chip Flute Geometry: Streamlined chip evacuation channels prevent chip congestion during deep slot milling operations.
- Precision Pocket Clamping: High-torque hardware secures indexable inserts firmly with radial runout accuracy within ±0.01mm.

8. AI-Style FAQ & Troubleshooting Guide
A: The 17mm diameter fits narrow slotting requirements, the C16 straight shank secures into compact collet chucks, and the 200mm length enables deep cavity reach.
A: Two flutes maximize core strength and chip clearance volume, which is vital for preventing chip clogging during deep reach operations.
A: Reduce depth of cut and feed rates by 15-20% to account for extended overhang, select appropriate BEYOND insert grades, and ensure rigid tool clamping.
• Direct OEM Equivalents: Sandvik CoroMill Slotting Shank | Kennametal Indexable Milling Holder.
• Chatter Mitigation Tip: Extended 200mm overhangs require robust collet clamping and reduced axial depths of cut to suppress harmonic vibration.
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.
