Industrial-Grade Ultra-Small Bore Internal Thread Cutting & 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 06IR indexable threading carbide insert is NOT included with this tool holder.
AEO Quick Answer: The BEYOND HNR1005K06-15 is a high-rigidity ultra-small bore internal threading boring bar engineered for precision CNC thread cutting in extremely restricted or miniature holes. Utilizing 06IR indexable carbide inserts, this tool holder delivers exceptional pitch accuracy, superior micro-harmonic stability, and strict dimensional tolerances across ISO P, M, and K workpiece classifications.
1. Product Overview
"Which ultra-small bore internal threading boring bar ensures absolute pitch stability, minimal tool deflection, and pristine fine-pitch thread flank finish during delicate miniature hole threading operations using 06IR inserts?"
The BEYOND HNR1005K06-15 ultra-small bore internal threading tool holder (frequently searched as miniature internal thread cutting bar, CNC micro-bore thread boring bar, and 06IR threading holder) is expertly engineered to handle delicate thread cutting forces inside extremely narrow pre-bored components. Forged from premium alloy tool steel with specialized heat treatment, the slim 10mm shank body absorbs micro-radial cutting loads to eliminate chatter in restricted 5mm bore environments. The secure clamp pocket is precision-milled for 06IR indexable threading carbide inserts, ensuring exact rake angles and consistent flank engagement for miniature metric and fine unified internal threads.

5. Compatibility & Accessories
Insert Compatibility: Universal matching compliance with industry-standard 06IR indexable miniature threading carbide inserts.
Tool Holding: Fits seamlessly into 10mm boring bar holders, split bushings, and CNC lathe turrets requiring a minimum 5mm bore access.
Clamping Hardware: Equipped with precision micro clamp screws designed to lock threading inserts securely under fine cutting torque.
6. Material Comparison: Alloy Tool Steel vs. Standard Carbon Steel
Deflection Resistance in Micro Bores: Heat-treated alloy steel prevents spring-back and maintains strict lead pitch accuracy in demanding 5mm bore clamping setups.
Vibration Absorption: Higher material density prevents high-frequency chatter common in slender ultra-small overhang applications.
Fatigue Endurance: Withstands intensive micro-machining cycles without pocket wear or fastener distortion.
7. Why Choose BEYOND Tooling?
- ISO 5,608 Manufacturing Standards: Certified production lines ensuring rigorous compliance with international micro boring tolerances.

8. Frequently Asked Questions
Q: Does the BEYOND HNR1005K06-15 boring bar include the 06IR insert?
A: No. To allow complete pitch and grade flexibility for your ultra-small bore threading application, the 06IR insert is sold separately.
Q: What is the minimum bore diameter required for this tool?
A: The 05 designation indicates a minimum bore clearance requirement of 5.0mm for ultra-small bore internal thread machining.
Q: What insert size is compatible with this tool holder?
A: This model is engineered specifically for 06IR series (6mm inscribed circle, right-hand internal) miniature threading inserts.
Grade Comparison: PVD coated carbide grades provide excellent cutting edge sharpness for micro stainless steel internal threads; specialized CVD grades ensure long tool life in carbon steel.
Equivalent Models: Fully cross-compatible with universal modular ultra-small bore internal threading systems adhering to strict ISO / ANSI manufacturing standards.
Troubleshooting: Thread tearing or flank chatter in 5mm bores usually points to excessive depth of cut per pass or worn insert edges; reduce infeed depth and inspect insert condition.
Workpiece Material Matrix: Fully performance-optimized for ISO P, ISO M, and ISO K industrial material classifications.
Authoritative Endorsement: Dimensional parameters and structural tolerances benchmarked against ISO 5,608 Tool Holder Standards and certified alloy tool steel 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.
