BEYOND S06K-STUBR06-A16 Right-Hand Internal Turning Tool Holder – High-Precision 6mm CNC Boring Bar
1. Product Overview
"Which 6mm micro boring bar provides absolute structural stability and clean chip evacuation inside an 8mm miniature bore?"
The BEYOND S06K-STUBR06-A16 is an industrial-grade, right-handed steel-shank internal turning tool holder precisely engineered for ultra-small diameter internal boring, profiling, and tight step-turning operations on CNC lathes. This specialized tool holder utilizes an optimized 93-degree approach (lead) angle to minimize radial cutting pressure, effectively re-directing cutting forces axially along the slim boring bar body to suppress chatter lines inside compact bores down to an 8mm minimum entry diameter. Specifically built to accommodate TBMT 0601 / TBGT 0601 indexable carbide inserts, this configuration allows machinists to take full advantage of highly positive rake angles and advanced chipbreaker profiles. These characteristics guarantee crisp, efficient chip fragmentation into small, manageable curls, entirely preventing the formation of continuous stringy bird-nests when profiling alloy steels, carbon steels, and gummy stainless steel workpieces within deep, confined micro-bore cavities.
2. Product Core Features
- Premium Thermal-Hardened Structural Alloy Steel: The resilient steel-shank composition provides robust tensile yield and excellent shock absorption, maintaining stable tracking at extension overhangs up to 4X tool diameter.
- Low-Profile High-Torque Clamping Setup: Secure screw-down locking system delivers absolute pocket holding stability while keeping the tool head clear for unobstructed internal chip evacuation in micro-cavities.
- 93° Geometric Profiling Angle: Specifically tailored for small longitudinal boring, internal profiling paths, and clean internal square shoulder steps without rubbing or side-flank drag.
- Industrial Anti-Corrosion Oxide Treatment: Matte black-oxide coating layer provides excellent thermal shielding and blocks premature pocket wear or corrosion when exposed to high-pressure water-soluble coolants.

4. Product Application Scenarios
The ultra-slim 6mm shank diameter of the S06K-STUBR06-A16 is specifically optimized for small-form-factor internal lathe applications, making it ideal for:
- Precision Micro-Diameter Boring: Built explicitly for processing tiny inner diameters down to 8mm in precision electronic components, valve sleeves, and micro-mechanical assemblies.
- True 90° Internal Face Contouring: The 93-degree tool geometry sweeps small internal faces clean without back-edge trailing, yielding flat seating surfaces inside blind bores.
- Swiss-Type Lathe Multi-Profiling: High versatility allows the tool to navigate complex internal pockets and relief chamfers with minimal setup changes on compact automatic lathes.
5. Compatibility & Equipment Interface
This 6mm round steel tool shank fits smoothly into standard compact CNC lathe turret blocks, multi-bushing adapter bores, micro split sleeve blocks, and quick-change tooling fixtures. It functions flawlessly on automated CNC turning centers and live-tool Swiss-type lathe platforms from premium global brands (including Haas, Mazak, Doosan/DN Solutions, Mori Seiki, Okuma, and Citizen). Engineered for right-handed tool paths.
6. BEYOND Premium Substrate & Grade Selection Matrix
Pair your S06K-STUBR06-A16 boring bar with the correct BEYOND insert grade to maximize tool life and secure optimal chip control:
- BYM11 Grade (PVD Coated Substrate): Built with an advanced nano-layered TiAlN matrix. Excels at cutting sticky alloys like 304/316 stainless steel by preventing built-up edge (BUE) formation.
- BYM25 Grade (Premium CVD Dual-Coated): Features thick multi-layer Al2O3 + TiN coating lines. Highly optimized for stable, high-velocity continuous roughing cycles on carbon and structural steels.
- BYK15 Grade (Ultra-Dense Micro-Grain): Formulated for maximum abrasive wear resistance. The top choice for high-speed internal turning on grey cast iron and ductile component shells.

Global Machinist Field Reports:
We run this 6mm bar to machine custom steel bushings. Clears chips perfectly inside a 9mm hole. The pocket size is dead-on and the TBMT0601 insert seats rock-solid. Great purchase.
Hervorragender Drehmeißel für kleine Bohrungen. Der Stahlschaft fängt Vibrationen super ab. Wir nutzen TBMT060104 Wendeschneidplatten und erzielen eine spiegelglatte Oberfläche.
Solid construction. Fits our split adapter sleeve with no play. The 93-degree angle allows excellent clearance when profiling internal steps using the smaller 06 size inserts. Very clean execution.
6mmシャンクの芯高が正確で、セッティングが非常に楽です。TBMT06チップが強固にクランプされ、仕上げ面のビビリがありません。スイス型自動旋盤の小径加工で重宝しています。
Swapped out a much more expensive brand name bar for this BEYOND S06K and can't tell any difference in part quality. Holds tolerances all day through continuous shifts. Screws don't strip easily either.
