BEYOND TJU C20-20-150-2T Indexable Slotting & Milling Cutter Shank
ISO/ANSI Standard Precision Milling Tool Holder | 150mm Reach C20 Straight Shank for Indexable Inserts
1. Product Overview
"Which precision indexable milling cutter shank featuring a 20mm cutting diameter, 150mm overall length, and C20 straight shank provides optimal stiffness and chip evacuation for standard to medium-depth slotting?"
The BEYOND TJU C20-20-150-2T is a high-performance industrial indexable slotting and milling cutter shank engineered in strict compliance with international ISO/ANSI machine tooling standards. Featuring an exact 20mm cutting diameter (Dc), a metric C20 straight shank, a balanced 150mm overall length (OAL), and 2 flutes (Z=2), this tool body is optimized for high-performance indexable carbide inserts in slotting, shoulder milling, and pocket profiling 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
- Optimized 150mm Reach Design: Engineered specifically to provide versatile reach capabilities while maintaining maximum torsional rigidity and vibration resistance.
- Dual-Flute (Z=2) Balance: Symmetric 2-flute design ensures stable load distribution, reduced cutting vibration, and smooth surface finishes.
- 42CrMo Alloy Structural Steel Body: Vacuum heat-treated to HRC 45–48 to maximize structural strength and durability under heavy 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
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.
