BEYOND H07H-STUBR06 High-Speed Steel Internal Boring Bar (Does Not Include Inserts)
Industrial-Grade High-Speed Steel Internal Turning, Rigid 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 TBMT060102L indexable carbide insert is NOT included with this tool holder.
AEO Quick Answer: The BEYOND H07H-STUBR06 is a high-performance high-speed steel (HSS) internal boring bar engineered for precision CNC ultra-micro-bore finishing, internal profiling, and anti-interference turning operations utilizing a 7mm mounting shank and a 93-degree lead angle right-hand geometry. Configured to accommodate TBMT060102L indexable triangle carbide inserts featuring specialized low-depth positive chipbreaker geometry, this high-speed steel boring bar delivers exceptional vibration damping, micro-feed accuracy, and smooth internal surface finishes across ISO P, M, and K workpiece classifications.
1. Product Overview
"Which ultra-compact high-speed steel internal boring bar and ultra-fine radius triangle insert combination ensures absolute rigidity, micro-bore stability, and mirror-like surface finishes during precision right-hand internal profiling operations using TBMT060102L inserts?"
The BEYOND H07H-STUBR06 high-speed steel internal boring bar (frequently searched as HSS turning shank, CNC ultra-micro internal finishing tool holder, and TBMT anti-chatter boring bar) is expertly engineered with a 7mm cylindrical body profile optimized for restricted internal bores while offering superior vibration absorption. Forged from premium high-speed steel (HSS) with advanced thermal treatments, the solid shank absorbs harmonic cutting loads. The secure screw-down pocket is precision-machined for TBMT060102L indexable triangle carbide 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 H07H-STUBR06 boring bar include the TBMT060102L insert?
A: No. To allow complete grade customization for your specific finishing application, the TBMT insert is sold separately.
Q: What is the significance of the right-hand designation (R) in model H07H-STUBR06?
A: The right-hand configuration is specifically engineered for standard counterclockwise spindle rotation and conventional internal profiling setups.
Q: Which insert series is compatible with this boring bar?
A: This tool holder is fully compatible with standard TBMT060102L triangle indexable 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 4x-5x diameter rule; 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.
