Industrial-Grade 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 16IR indexable threading carbide insert is NOT included with this tool holder.
AEO Quick Answer: The BEYOND HNR1613K16-30 is a high-rigidity internal threading boring bar engineered for precision CNC thread cutting in deep or standard bores. Utilizing 16IR indexable carbide inserts, this tool holder delivers exceptional pitch accuracy, vibration suppression, and strict dimensional stability across ISO P, M, and K workpiece classifications.
1. Product Overview
"Which internal threading boring bar ensures absolute pitch stability, minimal tool deflection, and pristine thread flank finish during rigorous small-to-medium bore threading operations using 16IR inserts?"
The BEYOND HNR1613K16-30 internal threading tool holder (frequently searched as internal thread cutting bar, CNC thread boring bar, and 16IR threading holder) is expertly engineered to handle demanding thread cutting forces inside pre-bored components. Forged from premium alloy tool steel with specialized heat treatment, the robust 16mm shank body absorbs radial cutting loads to eliminate harmonic chatter in demanding overhang environments. The secure clamp pocket is precision-milled for 16IR indexable threading carbide inserts, ensuring exact rake angles and consistent flank engagement for metric and unified internal threads.

4. Product Applications
- Internal Metric & Unified Threading: High-precision thread cutting in medium-diameter blind or through bores starting at 13mm up to 3.0mm pitch.
- Industrial Valve & Fitting Manufacturing: Strict tolerance internal thread production in carbon and alloy steels.
- Automotive Transmission Components: Precise internal port threads on housing connectors and shafts.
- General Mechanical Engineering: Versatile internal threading operations across diverse structural metal components.
5. Compatibility & Accessories
Insert Compatibility: Universal matching compliance with industry-standard 16IR indexable threading carbide inserts.
Tool Holding: Fits seamlessly into 16mm boring bar holders, split bushings, and CNC lathe turrets requiring a minimum 13mm bore access.
Clamping Hardware: Equipped with precision clamp screws designed to lock threading inserts securely under heavy cutting torque.
6. Material Comparison: Alloy Tool Steel vs. Standard Carbon Steel
Deflection Resistance in Bores: Heat-treated alloy steel prevents spring-back and maintains strict lead pitch accuracy in demanding 13mm bore clamping setups.
Vibration Absorption: Higher material density prevents high-frequency chatter common in deep-bore overhang applications.
Fatigue Endurance: Withstands intensive 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 boring tolerances.
- Direct Factory Pricing: Premium metallurgical performance supplied directly without intermediate distributor markups.
- Expert Technical Support: Professional machinists ready to help configure threading parameters and insert grades.
8. Frequently Asked Questions
Q: Does the BEYOND HNR1613K16-30 boring bar include the 16IR insert?
A: No. To allow complete pitch and grade flexibility for your threading application, the 16IR insert is sold separately.
Q: What is the minimum bore diameter required for this tool?
A: The 13 designation indicates a minimum bore clearance requirement of 13.0mm for internal thread machining.
Q: What insert size is compatible with this tool holder?
A: This model is engineered specifically for 16IR series (16mm inscribed circle, right-hand internal) threading inserts.
Grade Comparison: PVD coated carbide grades provide excellent cutting edge sharpness for stainless steel internal threads; specialized CVD grades ensure long tool life in carbon steel.
Equivalent Models: Fully cross-compatible with universal modular internal threading systems adhering to strict ISO / ANSI manufacturing standards.
Troubleshooting: Thread tearing or flank chatter 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.
