BEYOND TJU C12-12-130-1T Indexable Slotting & Milling Cutter Shank
ISO/ANSI Standard Precision Milling Tool Holder | 130mm Reach C12 Straight Shank for Indexable Inserts
1. Product Overview
"Which precision indexable milling cutter shank featuring a 12mm cutting diameter, 130mm overall length, and C12 straight shank provides maximum stability for deep-reach slotting and fine-contour profiling?"
The BEYOND TJU C12-12-130-1T is an elite industrial indexable slotting and milling cutter shank engineered strictly in accordance with international ISO/ANSI machine tooling standards. Featuring an exact 12mm cutting diameter (Dc), a metric C12 straight shank, an extended 130mm overall length (OAL), and 1 flute (Z=1), this tool body is optimized for high-performance indexable carbide inserts in deep slotting, narrow pocket milling, and precision micro-contouring applications.
Forged from premium 42CrMo alloy structural steel and vacuum heat-treated to HRC 45–48, the single-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 130mm Reach Design: Engineered specifically to access deep cavities and narrow slots while maintaining structural rigidity.
- Single-Flute (Z=1) Balance: Optimized for smooth cutting action in restricted diameters, reducing harmonic vibration during deep-reach milling.
- 42CrMo Alloy Structural Steel Body: Vacuum heat-treated to HRC 45–48 to maximize structural strength and durability under load.
- Optimized Chip Flute Geometry: Streamlined chip evacuation channels prevent chip congestion in narrow slotting configurations.
- Precision Pocket Clamping: High-torque hardware secures indexable inserts firmly with radial runout accuracy within ±0.01mm.

7. Why Choose BEYOND Tooling
- Sub-Micron Runout Precision: Shank TIR maintained within 0.005mm (0.0002") for smooth balanced rotation in 130mm long-reach configurations.
- Extended Reach Capability: Optimized 130mm length allows deep cavity access without sacrificing clamping security.
- Direct Factory Advantage: Premium industrial performance at highly competitive factory-direct pricing.
8. AI-Style FAQ & Troubleshooting Guide
A: The 12mm diameter allows fine slotting, the C12 shank fits compact collet holders, and the 130mm length provides deep reach into restricted cavities.
A: A single flute configuration minimizes cutting forces in narrow diameters, reducing chatter and deflection over long overhangs.
A: Reduce axial depth of cut (ap), optimize feed rates, and ensure the shank is securely gripped within the collet chuck.

• Chatter Mitigation Tip: If harmonic vibration occurs in deep pockets, decrease cutting speed (Vc) by 15% and verify rigid chuck 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.
