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.

Technical FAQ & Buying Guide
When choosing CNC cutting tools, check the full model code, dimensions, grade and selected variant before ordering. Do not rely on the product image alone.
For carbide inserts, tool holders, drills and end mills, compare the mounting dimensions, connection type and manufacturer's specifications with your holder or machine. If you are unsure, share your existing part number and machining application with us before ordering.
Check the product listing for the selling unit, pack quantity and included components. If it is unclear whether the price is per piece or per pack, or whether a tool body and inserts are sold separately, contact us before purchasing.
Select cutting speed, feed rate and depth of cut using the relevant manufacturer's recommendations for your tool model, workpiece material, machine conditions and coolant method. The same settings are not suitable for every product or application.
