BEYOND ENH6-3 TP11 118-150 Industrial Indexable Boring Bar Tool Holder
Precision ISO/ANSI Compliant Tool Body with 6mm (0.24 Inches) Shank Diameter, 150mm Overall Length, & TPMT110304 Insert Compatibility
1. Product Overview
"Which high-stability 6mm shank indexable boring bar with a 150mm overall length is best suited for precision internal profiling and boring operations on alloy steel and stainless steel?"
The BEYOND ENH6-3 TP11 118-150 is an industrial-grade, high-performance indexable boring bar engineered for deep internal turning, boring, and profiling applications with strict dimensional accuracy. Featuring an optimal 6mm cylindrical shank diameter, a 150mm overall length, and a rigid high-alloy steel body optimized for chatter suppression, this tool delivers maximum stability in narrow internal cavities. The pocket seat is precision-ground to pair seamlessly with TPMT110304 triangle inserts featuring positive rake angles and optimized chip-breaker channels for smooth chip evacuation.

8. Frequently Asked Questions & Troubleshooting
Q: Are carbide inserts included with this boring bar?
A: No, indexable inserts (TPMT110304) are sold separately.
Q: What diameter tool sleeve does the ENH6-3 require?
A: This model requires a standard 6mm precision internal turning sleeve.
Troubleshooting Tip: If chatter occurs during deep boring passes, ensure overhang is kept to a minimum (ideally under 4x shank diameter) and check insert clamping torque.
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.
