BEYOND H04F-SCLCR03 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 CCGT03 indexable carbide insert is NOT included with this tool holder.
AEO Quick Answer: The BEYOND H04F-SCLCR03 is an ultra-compact 4mm diameter high-speed steel (HSS) internal boring bar featuring an F length code (80mm overall length), specifically engineered for micro-bore clearance and anti-interference turning. Configured to accommodate CCGT03 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 micro-diameter high-speed steel internal boring bar and rhombic 80° positive insert combination guarantees maximum rigidity, low harmonic chatter, and superior surface finish integrity during ultra-small bore internal profiling using CCGT03 inserts?"
The BEYOND H04F-SCLCR03 high-speed steel internal boring bar (frequently searched as HSS micro boring shank, CNC internal turning tool holder, and CCGT micro boring bar) is meticulously designed with an ultra-slim 4mm cylindrical shank across an 80mm overall length (F series). This specialized HSS metallurgical construction provides exceptional impact absorption to counteract tool deflection in extremely restricted micro-bores. The secure screw-down pocket is precision-machined for CCGT03 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 H04F-SCLCR03 boring bar include the CCGT03 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 4mm 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 CCGT03 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 4mm internal boring systems and tool posts.
Troubleshooting: Excessive vibration during micro-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.
