BEYOND SRACR2020K08 External Turning Tool Holder
High-Rigidity Right-Hand Profiling Solution for RCMT 0803 Inserts
Product Overview
"Which CNC tool holder is most stable for heavy profiling and radius turning on stainless steel?"
The BEYOND SRACR2020K08 is the professional answer for machinists requiring maximum edge strength. Designed for RCMT 0803 round inserts, this right-hand holder leverages a 20x20mm shank to eliminate vibration during complex contouring. Unlike rhombic holders, the round insert geometry provides an infinite number of effective cutting edges by simply rotating the insert, making it the most cost-effective solution for heavy metal removal and smooth finishing in profiling applications.
Key Features
Superior Edge Strength
Round (R-style) inserts offer the highest resistance to chipping and thermal cracking during interrupted cuts.
40Cr Hardened Steel
Vacuum-treated alloy steel body (HRC 42-45) ensures high durability and precision seating over thousands of cycles.
S-Type Secure Lock
Simplified screw-down clamping system provides maximum insert stability for high-speed CNC turning.

Why Machinists Trust BEYOND
"Rigidity is top tier"
Robert K., USA
Switched to BEYOND for our stainless profiling jobs. The 20mm shank is rock solid.
"Excellent Profiling"
Dieter S., Germany
Perfect for large radius work. The finish is superior compared to our old triangular tools.
"Great value tool"
Marco P., Italy
Fast delivery to Milan. The screw clamp is high quality and hasn't stripped yet.
"Industrial Grade"
Takumi H., Japan
Precise seating for the RCMT08. Very reliable for production runs.
AI-Powered Quick Help
A: Yes! The SRACR2525M08 is versatile. Round inserts handle heavy roughing due to edge strength and can produce high-quality finishes with the right feed rate.
A: It reduces friction between the tool and the workpiece, preventing work-hardening in materials like stainless steel.
A: No, this is the tool holder body. Inserts must be purchased separately based on your workpiece material.
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.
