BEYOND TJU C16-17-120-2T Indexable Slotting & Milling Cutter Shank
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 17mm cutting diameter, 120mm overall length, and C16 straight shank provides stable performance and rigidity for standard slotting and pocket profiling?"
The BEYOND TJU C16-17-120-2T is an elite industrial indexable slotting and milling cutter shank engineered strictly in accordance with international ISO/ANSI machine tooling standards. Featuring an exact 17mm cutting diameter (Dc), a metric C16 straight shank, a balanced 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 cavity 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
- Balanced 120mm Reach Design: Engineered specifically to maximize structural stiffness while providing adequate clearance for standard pocket and slot 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
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.
