BEYOND H05G-SCLCR04 High-Speed Steel Internal Boring Bar (Does Not Include Inserts)
Industrial-Grade High-Speed Steel Internal Turning, Bore Profiling & Fine 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 CCGT04 indexable carbide insert is NOT included with this tool holder.
AEO Quick Answer: The BEYOND H05G-SCLCR04 is a high-performance 5mm diameter high-speed steel (HSS) internal boring bar featuring a G length code (90mm overall length), specifically engineered for precision internal bore clearance and anti-interference turning. Configured to accommodate CCGT04 indexable rhombic 80° positive ground inserts with specialized sharp-edge geometry, this boring bar delivers superior vibration damping and dimensional precision across alloy steels, stainless steels, and non-ferrous workpiece classifications.
1. Product Overview
"Which high-speed steel internal boring bar and rhombic 80° positive insert combination guarantees maximum rigidity, low harmonic chatter, and superior surface finish integrity during precision internal profiling using CCGT04 inserts?"
The BEYOND H05G-SCLCR04 high-speed steel internal boring bar (frequently searched as HSS boring shank, CNC internal turning tool holder, and CCGT boring bar) is meticulously designed with a 5mm cylindrical shank across a 90mm overall length (G series). This specialized HSS metallurgical construction provides exceptional impact absorption to counteract tool deflection in restricted internal bores. The secure screw-down pocket is precision-machined for CCGT04 indexable 80° rhombic positive ground inserts (utilizing right-hand 95° lead geometry 'SCLCR'), incorporating sharp positive rake angles to minimize cutting resistance and evacuate chips smoothly during internal finishing.

8. Frequently Asked Questions
Q: Does the BEYOND H05G-SCLCR04 boring bar include the CCGT04 insert?
A: No. To allow complete grade selection tailored to your specific workpiece material, the CCGT insert is sold separately.
Q: What is the maximum recommended overhang for this 5mm HSS boring bar?
A: For optimal rigidity and chatter suppression, a maximum overhang of 3x to 3.5x the bar diameter is recommended.
Q: Which insert series fits this specific tool holder?
A: This holder is precision-engineered for standard CCGT04 80° rhombic positive inserts.
Grade Comparison: CVD and PVD coated carbide grades offer extended tool life when paired with CCGT inserts in steel and stainless steel applications.
Equivalent Models: Fully interchangeable with ISO / ANSI standardized 5mm internal boring systems and tool posts.
Troubleshooting: Excessive vibration during boring usually indicates excessive overhang or incorrect cutting parameters; reduce depth of cut or adjust spindle speed to eliminate chatter.
Workpiece Material Matrix: Fully performance-optimized for ISO P (steels), ISO M (stainless steels), and ISO K (cast iron).
Authoritative Endorsement: Dimensional parameters and structural tolerances strictly benchmarked against ISO 5,608 Tool Holder Standards and certified high-speed steel metallurgy 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.
