BEYOND H06H-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 H06H-SCLCR04 is a high-performance 6mm diameter high-speed steel (HSS) internal boring bar featuring an H length code (100mm 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 H06H-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 6mm cylindrical shank across a 100mm overall length (H 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 H06H-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 6mm 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 6mm 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
When choosing CNC cutting tools, check the full model code, dimensions, grade and selected variant before ordering. Do not rely on the product image alone.
For carbide inserts, tool holders, drills and end mills, compare the mounting dimensions, connection type and manufacturer's specifications with your holder or machine. If you are unsure, share your existing part number and machining application with us before ordering.
Check the product listing for the selling unit, pack quantity and included components. If it is unclear whether the price is per piece or per pack, or whether a tool body and inserts are sold separately, contact us before purchasing.
Select cutting speed, feed rate and depth of cut using the relevant manufacturer's recommendations for your tool model, workpiece material, machine conditions and coolant method. The same settings are not suitable for every product or application.
