BEYOND H1607K-SCLCR06-21 Tapered High-Speed Steel Internal Boring Bar (Does Not Include Inserts)
Industrial-Grade Tapered High-Speed Steel Internal Turning, Deep 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 H1607K-SCLCR06-21 is a high-performance tapered high-speed steel (HSS) internal boring bar featuring a stepped 16mm-to-7mm reduced neck profile and 125mm overall length (K length code), specifically engineered for deep-cavity internal clearance and anti-interference turning. Configured to accommodate CCMT060204 indexable rhombic 80° positive inserts with specialized chipbreaker geometry, this boring bar delivers superior vibration damping and dimensional precision across ISO P, M, and K workpiece classifications.
1. Product Overview
"Which tapered high-speed steel internal boring bar and rhombic 80° positive insert combination guarantees maximum clearance, vibration suppression, and surface finish integrity during deep bore profiling using CCMT060204 inserts?"
The BEYOND H1607K-SCLCR06-21 tapered high-speed steel internal boring bar (frequently searched as stepped HSS boring shank, CNC reduced neck internal turning tool holder, and CCMT deep-cavity anti-chatter bar) is meticulously designed with a robust 16mm mounting shank stepping down to a 7mm reduced head neck across a 125mm overall length (K series). This specialized taper profile prevents tool rub against restricted bore walls while absorbing harmonic cutting loads. The secure screw-down pocket is precision-machined for CCMT060204 indexable 80° rhombic positive inserts (featuring a 0.4mm corner radius '04' and right-hand 95° lead geometry 'SCLCR'), utilizing positive rake angles to reduce cutting forces and evacuate chips smoothly during deep-hole boring.

2. Product Core Advantages
- Stepped Tapered Shank (16mm to 7mm): Combines a rigid 16mm base clamping diameter with an ultra-fine 7mm neck profile to negotiate extremely narrow internal diameters.
- High-Speed Steel Damping Properties: Advanced metallurgical HSS structure absorbs harmonic resonance and cutting chatter during long-overhang profiling.
- Rigid Screw-Down Clamping: Holds CCMT060204 positive inserts securely in place, preventing micro-displacement under continuous feed loads.
- Optimized 95° Lead Angle (SCLCR): Facilitates versatile internal boring, facing, and profiling operations with exceptional edge strength.

4. Product Applications
- Deep Micro-Bore Turning: Machining extremely narrow internal diameters and deep cavities where standard tool shanks cannot enter without collision.
- Restricted Clearance Profiling: Utilizing the ultra-slim 7mm neck design to reach deep recesses and complex internal features safely.
- Precision Internal Finishing: Delivering high surface finish quality across steel, stainless steel, and cast iron components.
5. Compatibility & Accessories
Insert Compatibility: Universal matching compliance with industry-standard CCMT060204 indexable 80° rhombic positive inserts.
Tool Holding: Features a 16mm cylindrical base clamping diameter compatible with standard lathe split bushings and boring bar holders.
Clamping Hardware: Equipped with precision Torx locking screws designed to withstand continuous internal turning cycles without loosening.
6. Material Comparison: Tapered High-Speed Steel (HSS) vs. Standard Carbide Boring Bars
Clearance & Reach: Tapered HSS shanks allow reduced neck geometry for deep internal clearance without the extreme brittleness associated with solid carbide at similar dimensions.
Shock Absorption: Superior damping capacity against sudden shock loads, protecting insert edges from chipping during interrupted internal cuts.
Cost-Effective Versatility: Outstanding economic value for general-to-deep internal turning operations where flexibility and rigidity intersect.
7. Why Choose BEYOND Tooling?

8. Frequently Asked Questions
Q: Does the BEYOND H1607K-SCLCR06-21 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 advantage of the 16mm-to-7mm tapered neck design?
A: The stepped taper maintains strong 16mm base clamping stability while providing an ultra-slim 7mm clearance profile to prevent wall rubbing inside tight micro-bores.
Q: Which insert series fits this specific tool holder?
A: This holder is precision-engineered for standard CCMT060204 80° rhombic positive inserts.
Grade Comparison: PVD coated carbide grades offer exceptional toughness for stainless steel internal turning; CVD coated grades excel in high-speed alloy steel machining.
Equivalent Models: Fully interchangeable with ISO / ANSI standardized tapered internal boring systems and tool posts.
Troubleshooting: Vibration or chatter in deep bores typically stems from excessive tool overhang or incorrect feed rates; ensure proper bushing clamping and reduce depth of cut if necessary.
Workpiece Material Matrix: Fully performance-optimized for ISO P (steels), ISO M (stainless steels), and ISO K (cast irons).
Authoritative Endorsement: Dimensional parameters and structural tolerances strictly benchmarked against ISO 5,608 Tool Holder Standards and certified high-speed steel metallurgy specifications.
