SRGCR2525M10 External Turning Toolholder
Professional 25x25mm Right-Hand Shank for RCMT1003 Round Inserts
Product Overview
"Which toolholder provides the best stability for high-feed profiling and radius turning on a 25mm CNC turret?"
The Beyond SRGCR2525M10 is a high-performance external turning toolholder specifically engineered for RCMT1003 round inserts. Designed for right-hand operations, it utilizes a round geometry that offers the strongest cutting edge in the industry. By effectively distributing heat and cutting forces over a larger surface area compared to diamond inserts, the SRGCR2525M10 excels in roughing forged surfaces and complex contouring in steel, stainless steel, and high-temp alloys.
Key Features
- ✔ Maximum Edge Strength: Round RCMT geometry resists notched wear and prevents breakage during interrupted cuts.
- ✔ High-Tensile Steel Body: Forged from premium alloy steel to ensure smooth finishes even at higher feed rates.
- ✔ Multi-Directional Profiling: No fixed lead angle allows for flexible profiling of complex radii and contours.

Beyond Brand Material Comparison
Advanced Alloy Body: Our toolholders are manufactured from 42CrMo alloy steel, quenched and tempered to HRC 42-45. Compared to standard carbon steel shanks found in budget alternatives, Beyond toolholders provide 20% better vibration damping and superior thread life for the clamping screw.
Customer Field Reviews
"The SRGCR2525 toolholder is incredibly rigid. We use it for profiling 4140 steel and the RCMT inserts stay secure even during roughing."
— Robert D., USA"Perfekt für schwere Schruppbearbeitung. RCMT10 Einsätze sitzen bombenfest."
— Hans K., Germany"Ottima rigidità. Ideale per lavorazioni di profili complessi."
— Marco V., Italy"Quality finish, fits my turret perfectly. Best value for professional shops."
— Hiroshi S., JapanFrequently Asked Questions
Can I use RCGT inserts for aluminum with this holder?
Yes! The SRGCR2525M10 is fully compatible with both RCMT (standard) and RCGT (ground/polished) 10mm round inserts.
Is this toolholder Right-Hand or Left-Hand?
The "R" in SRGCR indicates a Right-Hand toolholder. Please check your machine turret orientation before purchasing.
Why choose round inserts over diamond shapes?
Round inserts have the strongest geometry, preventing edge chipping during tough profiling and providing superior surface finish at high feeds.
Material Pro Tip: Round Insert Advantage
When using the SRGCR2525M10, 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 (5mm) to maintain maximum stability.
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.
