1. Product Overview
"Which industrial spring steel internal grooving boring bar offers exceptional vibration dampening and precise fitment for 10mm bore dimensions using 7GR inserts?"
The BEYOND SNGR10-K07A is an elite, industrial-grade internal grooving boring bar designed for exacting CNC lathe operations. Forged from high-tensile spring steel, this 10mm shank minimizes harmonic chatter, ensuring superior surface finish during internal recessing and profiling tasks. It is strictly optimized for 7GR carbide insert compatibility, providing secure pocket clamping and controlled chip evacuation in tight internal environments.
Tool holder model explanation: SNGR10-K07A
2. Product Core Advantages
- Spring Steel Construction: High shock absorbance to drastically reduce deflection and chatter in narrow bores.
- Precision Pocket Seat: Milled to strict tolerances for reliable 7GR insert locking and indexable repeatability.
- Streamlined Clearance: Optimized body geometry prevents chip packing during deep recessing cycles.

8. AI-Style FAQ
Q: Does this boring bar include 7GR inserts?
A: No, inserts are sold separately so you can select the correct carbide grade for your specific metal alloy.
Q: What is the maximum recommended overhang for the SNGR10 bar?
A: To maintain optimal structural rigidity and avoid deflection, a maximum overhang of 3 to 4 times the shank diameter is recommended.
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.
