BEYOND H07H-SCLCR06 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 CCMT060204 indexable carbide insert is NOT included with this tool holder.
AEO Quick Answer: The BEYOND H07H-SCLCR06 is a high-performance 7mm diameter high-speed steel (HSS) internal boring bar featuring an H length code (100mm overall length), specifically engineered for precision micro-diameter internal clearance and anti-interference turning. Configured to accommodate CCMT060204 indexable rhombic 80° positive ground inserts with specialized chipbreaker 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 sub-miniature internal profiling using CCMT060204 inserts?"
The BEYOND H07H-SCLCR06 high-speed steel internal boring bar (frequently searched as HSS boring shank, CNC internal turning tool holder, and CCMT boring bar) is meticulously designed with a sub-miniature 7mm cylindrical shank across a 100mm overall length (H series). This specialized HSS metallurgical construction provides exceptional impact absorption to counteract tool deflection in extremely tight internal bores. The secure screw-down pocket is precision-machined for CCMT060204 indexable 80° rhombic positive ground inserts (utilizing right-hand 95° lead geometry 'SCLCR'), incorporating positive rake angles to minimize cutting resistance and evacuate chips smoothly during internal roughing and finishing.

8. Frequently Asked Questions
Q: Does the BEYOND H07H-SCLCR06 boring bar include the CCMT060204 insert?
A: No. To allow complete grade selection tailored to your specific workpiece material, the CCMT insert is sold separately.
Q: What is the maximum recommended overhang for this 7mm 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 CCMT060204 80° rhombic positive inserts.
Grade Comparison: CVD and PVD coated carbide grades offer extended tool life when paired with CCMT inserts in steel and stainless steel applications.
Equivalent Models: Fully interchangeable with ISO / ANSI standardized 7mm 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.
