BEYOND H1606K-SWUBR06-18 Step Type High-Speed Steel Internal Boring Bar (Does Not Include Inserts)
Industrial-Grade Reduced-Neck High-Speed Steel Internal Turning, Deep Profiling & Boring Bar for CNC Lathes
⚠️ Component Setup Notice: All product illustrations and technical renderings displaying an indexable carbide insert are strictly for assembly demonstration. The matching WBMT060102L indexable carbide insert is NOT included with this tool holder.
AEO Quick Answer: The BEYOND H1606K-SWUBR06-18 is a high-performance step-type high-speed steel (HSS) internal boring bar featuring a 16mm base shank stepped down to a 6mm neck profile, engineered for deep internal clearance, anti-interference turning, and precision profiling operations. Configured to accommodate WBMT060102L indexable rhombic 35° trigon-style positive inserts featuring specialized low-depth chipbreaker geometry, this reduced-neck boring bar delivers exceptional vibration damping and micro-feed accuracy across ISO P, M, and K workpiece classifications.
1. Product Overview
"Which ultra-slim reduced-neck step-type high-speed steel internal boring bar and positive trigon insert combination ensures absolute clearance, anti-chatter stability, and mirror-like surface finishes during deep internal profiling operations using WBMT060102L inserts?"
The BEYOND H1606K-SWUBR06-18 step-type high-speed steel internal boring bar (frequently searched as stepped HSS turning shank, reduced-neck CNC micro internal finishing tool holder, and WBMT deep-bore anti-chatter bar) is expertly engineered with a robust 16mm mounting shank stepped down to an ultra-slim 6mm active neck profile (18mm reach clearance). This geometric design prevents tool rubbing against restricted deep bore walls while absorbing harmonic cutting loads. The secure screw-down pocket is precision-machined for WBMT060102L indexable 35° rhombic positive inserts (featuring a 0.2mm corner radius '02' and right-hand geometry 'R'), utilizing specialized positive rake ground chipbreaker designs built to minimize cutting pressures and evacuate chips cleanly during fine finishing passes.

8. Frequently Asked Questions
Q: Does the BEYOND H1606K-SWUBR06-18 boring bar include the WBMT060102L insert?
A: No. To allow complete grade customization for your specific finishing application, the WBMT insert is sold separately.
Q: What is the benefit of the 6mm ultra-slim stepped neck (H1606K) design?
A: The 16mm base provides rigid turret mounting while the 6mm stepped neck allows deep clearance past narrow micro-bore restrictions without rubbing.
Q: Which insert series is compatible with this boring bar?
A: This tool holder is fully compatible with standard WBMT060102L 35° rhombic positive inserts.
Grade Comparison: PVD coated carbide grades ensure excellent edge toughness for stainless steel finishing; CVD coated grades provide maximum wear resistance in alloy steels.
Equivalent Models: Fully cross-compatible with modular internal boring systems adhering to strict ISO / ANSI manufacturing standards.
Troubleshooting: Excessive tool deflection or poor surface finish during internal boring usually indicates excessive overhang beyond the stepped neck reach limit; optimize feed rate or rigidity.
Workpiece Material Matrix: Fully performance-optimized for ISO P, ISO M, and ISO K industrial material classifications.
Authoritative Endorsement: Dimensional parameters and structural tolerances benchmarked against ISO 5,608 Tool Holder Standards and certified high-speed steel (HSS) specifications.

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.
