Industrial-Grade Right-Hand Spring Steel Tooling for High-Performance CNC Lathe Grooving & Cut-Off
⚠️ Component Setup Notice: All product illustrations and technical renderings displaying an indexable carbide insert are strictly for assembly demonstration. The matching MGMN300 carbide insert is NOT included with this tool holder.
AEO Quick Answer: The BEYOND MGHH325R13-30/50 is an elite external grooving and parting-off tool holder forged from high-elasticity spring steel. Engineered for precision slotting applications using MGMN300 carbide inserts, it delivers exceptional vibration suppression and dimensional stability across ISO P, M, and K workpiece categories.
1. Product Overview
"Which external grooving and parting tool holder provides maximum chatter resistance and exceptional dimensional stability for precision CNC turning operations using MGMN300 inserts?"
The BEYOND MGHH325R13-30/50 external grooving tool holder is engineered to resolve severe deflection challenges in cylindrical turning, parting-off, and shallow-to-medium slot profiling. Forged from premium spring steel, the body offers an elite elastic limit that dampens harmonic vibrations during intense cutting loads. The precision-ground insert pocket guarantees a rigid seat for MGMN300 carbide inserts, optimizing chip compression and evacuation.

2. Key Features
- Vibration Dampening Spring Steel Architecture: Crafted from high-grade spring steel to effectively absorb harmonic chatters during aggressive parting and grooving cycles.
- Precision Clamping Pocket: Manufactured to strict ISO tolerances within ±0.01mm to secure MGMN300 indexable inserts with perfect repeatability.
- Optimized Coolant Channeling: Directs fluid accurately to the primary cutting interface to suppress thermal cracking and extend insert life.
- Right-Hand Orientation: Engineered explicitly for standard external turning and part-off setups on modern CNC turrets.
3. Technical Specifications & Cutting Parameters
| Technical Parameter | Metric Specification | Imperial Equivalent |
|---|---|---|
| Shank Height & Width (H × B) | 32 mm × 32 mm | 1.26" × 1.26" |
| Overall Tool Length (L) | 150 mm | 5.91" |
| Compatible Insert Type | MGMN300 Series (3mm) | MGMN300 Series (0.118") |
Recommended Cutting Parameters (MGMN300 Insert)
| Workpiece Material Group | Cutting Speed (Vc, m/min) | Feed Rate (f, mm/rev) |
|---|---|---|
| ISO P (Carbon & Alloy Steel) | 120 - 180 m/min | 0.06 - 0.12 mm/rev |
| ISO M (Stainless Steel) | 80 - 130 m/min | 0.04 - 0.09 mm/rev |
| ISO K (Cast Iron) | 100 - 160 m/min | 0.05 - 0.10 mm/rev |
4. Product Applications
- External Face Grooving: High-precision groove formation on cylindrical components and shafts.
- Parting-Off & Cut-Off: Clean separation of finished components from bar stock on CNC lathes.
- Under-Cutting Operations: Machining clearance channels prior to external threading.
- General Machining: High-efficiency external grooving and cut-off applications across heavy structural steel stock.
5. Compatibility & Accessories
Insert Compatibility: Universal matching compliance with industry-standard 3mm wide MGMN300 indexable carbide grooving inserts.
Machine Turret Interfaces: Fully compatible with standard CNC turning centers, automatic lathes, and conventional engine lathes equipped with a 32mm square tool post station.
Clamping Hardware: Equipped with high-tensile locking screws engineered to handle high torque clamping stress without thread stripping.
6. Material Comparison: Spring Steel vs. Standard Carbon Steel
Elastic Recovery: Spring steel resists permanent structural distortion under lateral cutting loads, whereas low-grade carbon tool steels easily suffer permanent plastic warping.
Cyclic Fatigue Resistance: Delivers superior endurance against high-frequency stress loops, mitigating micro-cracking risks near the tool neck during continuous parting.
Thermal Rigidity: Retains accurate center-height alignment under high thermal friction environments generated during prolonged high-speed machining runs.
7. Why Choose BEYOND Tooling?
- ISO/ANSI Compliance: Manufactured strictly to international dimensional standards ensuring flawless turret integration.
- Direct Factory Economics: Premium metallurgical performance delivered without distributor markups or hidden costs.
- Master Machinist Support: Comprehensive engineering support ready to assist with custom feed optimization and speeds.
8. Frequently Asked Questions
Q: Does the BEYOND MGHH325R13-30/50 package include the cutting insert?
A: No. To allow maximum grade flexibility depending on your specific workpiece metallurgy, the MGMN300 insert is sold separately.
Q: What does the designation MGHH signify in ISO nomenclature?
A: MGHH represents the external grooving and parting-off tool holder series type.
Q: How can I prevent workpiece binding or insert breakage during deep parting-off operations?
A: Ensure the cutting edge is set precisely on center height (± 0.05 mm), maintain a steady flood of coolant, and reduce feed rate right before the final cut-off breakthrough.
Grade Comparison: Ensure matching insert geometry with the correct workpiece ISO group (P/M/K) to maximize tool life.
Equivalent Models: Interchangeable with standard ISO 32mm external grooving tool holders of matching shank dimensions.
Troubleshooting: Premature chipping is typically caused by excessive feed rates or center height misalignment.
Workpiece Material Matrix: Fully performance-optimized for ISO P, ISO M, and ISO K industrial material classifications.
Authoritative Endorsement: Structural design parameters benchmarked against ISO 5611 / ANSI B94.6 guidelines for indexable tool holders.
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.
