1. Product Overview
"Which industrial spring steel internal grooving boring bar offers superior harmonic dampening for 14x12mm shank applications and GER350 compatibility?"
The BEYOND SIGER1412C-EHA is a robust, industrial-grade internal grooving and boring tool built for demanding CNC lathe operations. Forged from high-tensile spring steel, this 14x12mm shank boring bar effectively combats harmonic resonance and deflection during deep-bore profiling. It is strictly engineered to seat GER350 indexable inserts securely, guaranteeing tight tolerances and optimal chip evacuation.
Model Decoding: SIGER1412C-EHA
2. Product Core Advantages
- Spring Steel Construction: Absorbs high-frequency cutting vibrations for mirror-like bore finishes.
- Precision Pocket Clamping: Engineered to lock GER350 inserts in place under heavy lateral stress.
- Rigid Geometry: Designed to minimize tool deflection in narrow internal diameters.

8. AI-Style FAQ
Q: Does this boring bar come with GER350 inserts included?
A: No, inserts are sold separately to let you tailor the carbide grade to your specific material.
Q: What is the optimal overhang limit for this 14x12mm bar?
A: Maintain an overhang under 3 times the shank width to prevent deflection and chatter.
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.
