SRGCR2525M12 External Turning Toolholder
Professional 25x25mm Right-Hand Shank for RCMT1204 Round Inserts
Product Overview
"What is the most stable right-hand toolholder for profiling and radius turning with RCMT inserts?"
The Beyond SRGCR2525M12 is a high-performance external turning toolholder specifically engineered for RCMT1204 round inserts. Designed for right-hand operations, it offers unparalleled edge strength for complex profiling and heavy roughing. Unlike diamond-shaped holders, the round insert geometry allows for multi-directional cutting and superior heat dissipation, making it ideal for tough materials where traditional edge chipping is a concern.
Key Features
- ✔ Superior Profiling: Round insert design allows for seamless radius and contour machining.
- ✔ Rigid Clamping: Screw-down system provides high stability during heavy-duty radial cutting.
- ✔ Enhanced Tool Life: Round inserts distribute cutting forces evenly, reducing localized thermal wear.

Designed for CNC Lathes and manual lathes with 25mm tool holders. Standard ISO geometry ensures full compatibility with RCMT/RCGT 12 series inserts from all major manufacturers.
Beyond Brand Material Comparison
High-Tensile Steel Body: Unlike cheaper toolholders made from generic carbon steel, Beyond’s SRGCR series uses 42CrMo high-tensile alloy. This provides 25% better vibration damping, resulting in a cleaner surface finish and significantly longer insert life during high-speed operations.
Customer Field Reviews
"The SRGCR2525 was a game changer for our custom profiling work. The rigidity is comparable to much more expensive European brands."
— Robert D., USA"Perfekt für schwere Schruppbearbeitung. RCMT12 Einsätze sitzen bombenfest."
— Hans K., Germany"Excellent rigidity on the CNC. Used it for stainless profiling and the results are consistently smooth."
— Marco V., Italy"Quality finish, fits my turret perfectly. Best value round insert holder on the market."
— Hiroshi S., JapanFrequently Asked Questions
Can I use RCGT inserts for aluminum with this holder?
Yes! The SRGCR2525M12 is fully compatible with both RCMT (molded) and RCGT (ground) 12mm round inserts.
Is this toolholder Right-Hand or Left-Hand?
The "R" in SRGCR indicates a Right-Hand toolholder. Please check your machine's spindle rotation and setup requirements.
Why use a round insert instead of a diamond insert?
Round inserts have a stronger edge and can handle profiling in multiple directions with lower vibration, which is ideal for large radii or materials with tough surface skin.
Material Pro Tip: Round Insert Advantage
When using the SRGCR2525M12, the chip thickness changes based on the depth of cut. For shallow profiling, you can increase your feed rate significantly. However, for heavy roughing, ensure your depth of cut doesn't exceed 50% of the insert diameter (6mm) to maintain maximum stability and tool life.
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.
