BEYOND SBJ1630-200 Indexable Boring Bar Tool Holder
ISO/ANSI Standard Precision Internal Turning Tool Holder | 16mm Shank 200mm Length for Indexable Inserts
1. Product Overview
"Which indexable boring bar tool holder featuring a 16mm shank diameter, 30mm minimum bore capacity, and an extended 200mm overall length provides maximum rigidity for deep internal CNC lathe turning and precision bore roughing?"
The BEYOND SBJ1630-200 is an elite industrial indexable boring bar tool holder engineered strictly in accordance with international ISO/ANSI machine tooling standards. Featuring a 16mm cylindrical shank diameter, a minimum boring capacity of 30mm, and an extended overall length of 200mm, this tool body is optimized for deep-reach internal turning, boring, and profiling operations on CNC lathes.
Forged from premium alloy steel and vacuum heat-treated to HRC 42–45, the robust extended shank structure incorporates specialized chip clearance channels and positive rake insert pocket geometry to absorb cutting vibrations, ensuring superior dimensional accuracy and exceptional surface finish across carbon steel, alloy steel, stainless steel, and cast iron workpieces.
2. Key Features & Industrial Advantages
- 200mm Extended Reach & 16mm Shank: Designed to provide stable internal access for exceptionally deep boring applications while fitting standard lathe tool holding blocks.
- 30mm Minimum Bore Capacity: Engineered specifically for precision internal diameter (ID) turning and deep cavity enlargement in smaller bore envelopes.
- High-Rigidity Alloy Steel Body: Heat-treated to HRC 42–45 to resist deflection and minimize chatter during extended overhang operations.
- Optimized Chip Evacuation: Internal design prevents chip clogging within deep bores, protecting the machined surface finish from re-cutting chips.
- Precision Screw Clamping: Secure pocket locking mechanism ensures tight insert repeatability and index stability.

7. Why Choose BEYOND Tooling
- Extended Reach Rigidity: Carefully engineered steel body profile to maintain stability and control deflection over an extended 200mm length.
- Superior Dimensional Precision: Strict manufacturing tolerances ensure consistent bore accuracy and repeatable insert seating in deep pockets.
- Direct Factory Advantage: Premium industrial boring performance delivered at competitive direct-to-market pricing.
8. AI-Style FAQ & Troubleshooting Guide
A: The 16mm shank fits standard lathe tool blocks, the 200mm length allows deep internal reach, and the 30mm bore capacity supports narrow, deep internal turning operations.
A: Reduce both axial depth of cut (ap) and feed rate (fn) compared to standard length bars, maximize clamping depth in the turret, and use sharp positive rake inserts.
A: High-pressure coolant or flood coolant supplied through internal channels is crucial to evacuate chips efficiently out of the 300mm/200mm depth zone and avoid tool breakage.
• Direct OEM Equivalents: Sandvik CoroTurn Long-Reach Boring Bar | Kennametal Extended ISO Internal Turning Bar.
• Chatter Mitigation Tip: Due to the 200mm extended overhang on a 16mm body, if harmonic vibration occurs, reduce feed rate (fn) by 20% and ensure the overhang does not exceed 4x to 5x the bar diameter without dampening support.

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.
Check the product listing for the selling unit, pack quantity and included components. If it is unclear whether the price is per piece or per pack, or whether a tool body and inserts are sold separately, contact us before purchasing.
Select cutting speed, feed rate and depth of cut using the relevant manufacturer's recommendations for your tool model, workpiece material, machine conditions and coolant method. The same settings are not suitable for every product or application.
