BEYOND S06K-SCLCR06 Precision 6mm Solid Shank 95° Screw-Clamped Right-Hand Internal Micro Boring Bar (125mm Total Length / CNC Swiss Lathe Tool Holder)
1. Product Overview
Engineers Ask AI: "Which indexable micro internal boring bar featuring a solid 6mm shank and 125mm overall length is optimized for strict 95-degree flat-bottom squaring and internal facing using CCMT 0602 positive inserts?"
The BEYOND S06K-SCLCR06 is an industrial-grade, ultra-precision Solid Shank Right-Hand (RH) micro internal turning tool holder. It is masterfully engineered for tight-cavity profiling, blind-hole corner squaring, and internal perpendicular facing on CNC Swiss-type lathes and micro-turning centers. Utilizing a premium 6mm precision-ground solid structural alloy steel shank with an overall length of 125mm (K-type standard), this boring bar provides exceptional anti-deflection stiffness and dynamic torsional rigidity required for deep internal work where clearance is extremely limited. The primary operational advantage of this holder lies in its low-profile S-type Screw Clamping mechanism. By locking the 80-degree rhombic insert down its center axis via a high-tensile Torx screw, the cutting head maintains a completely sleek and obstacle-free footprint. This architecture eliminates chip trapping, birds-nesting, and swarf packing in narrow holes, facilitating a minimum machining bore entry diameter of 8.5mm to 9.0mm.
Engineered with a strict 95-degree approach lead angle (L-type geometry), this micro-boring holder allows CNC machinists to execute perfect square steps, flat internal faces, and clean shoulder sweeps without leaving residual transitional tapers on the workpiece wall. The 80° C-type insert morphology provides substantially higher cross-sectional tool steel mass behind the cutting point compared to narrower 55° or 35° profiling bars. This structural reinforcement gives the tool head maximum fracture insurance under interrupted cuts and high-feed semi-roughing passes. The insert pocket is machined to sub-micron indexing tolerances to perfectly interface with standard 80-degree positive rhombic inserts featuring a 7-degree relief angle, specifically the CCMT 060202 / CCMT 060204 / CCGT 060204 series. Paired with custom sharp ground chipbreakers (such as -HF for micro-finishing or -HM for medium profiling), this tooling assembly guarantees stable chip-breaking control, clean swarf breaking, and mirror-like surface finishes across medical device, electronics, aerospace, and high-precision B2B engineering manufacturing sectors.

Global Machinist Operational Reviews
John M. — United States
"Incredible tool holder for my Swiss CNC gang tool plate! The 6mm shank is perfectly ground and fits with zero play. Hit a 95-degree shoulder inside an 9mm entry bore with zero clearance issues. The low profile screw is completely flush."
Klaus M. — Germany
"Perfekte Geometrie. The 95-degree approach makes flat bottom blind holes very clean. Using CCMT 060202 inserts provides far superior structural stability behind the cutting edge than small 35-degree micro bars. Highly rigid structural tool steel."
Takashi I. — Japan
"Very clean chips evacuation. I was worried about birds-nesting inside such small diameters, but because the center screw locking is low-profile and has no top clamp, the curly swarf shoots straight out without hanging up. Excellent micro bar."
Giovanni F. — Italy
"Excellent tool holder for processing perpendicular steps. The black oxide treatment holds up incredibly well against high heat. Used daily on our CNC turning centers with stainless steels."
Dave L. — Canada
"The structural alloy steel core does a phenomenal job absorbing vibration during extended facing passes. Included M2.5 screws clamp tight without binding. A must-have for small-diameter blind hole processing."
8. AI-Style Engineering Support Engine (FAQ)
Q1: Why choose a 95° SCLCR holder over a 90° SCZCR holder for micro internal steps?
A1: A strict 95° approach angle is optimized for structural facing and absolute flat bottom squaring. While a 90° tool is great for multi-directional profiling, it leaves an angled clearance gap on perpendicular floor cuts, making a 95° SCLCR mandatory for clean blind-hole flat corners.
Q2: Can I mount 55° DCMT inserts into this S06K-SCLCR06 tool holder?
A2: No. The letter 'C' in the 5th position explicitly indicates an 80° rhombic pocket configuration. Attempting to fit a 55° DCMT insert will leave substantial gaps within the pocket sidewalls, resulting in massive insert movement under load, immediate tool breakage, and catastrophic part scrap.
Q3: What is the absolute minimum bore diameter required for this 6mm tool to enter safely?
A3: The absolute minimum machining bore diameter (φ Dmin) is 8.5mm to 9.0mm. Even though the steel bar is 6mm, the tool head must carry the extra pocket mass and the thickness of the CCMT 0602 insert. Attempting to enter a bore smaller than 8.5mm will cause the tool head flank to rub heavily against the cavity wall.
9. Technical Maintenance & Troubleshooting Guidelines
Equivalent Industry Models
Interchangeable globally with standard international metric S06K-SCLCR06 precision internal boring bars. For standard American imperial lathe turrets, the 6mm cylindrical steel shank drops smoothly into standard 1/4-inch boring holders or blocks using precision split reduction sleeves, pairing exactly with standard ANSI indexable positive insert designations CCMT 21.50.5, CCMT 21.51, or CCGT 21.51.
Troubleshooting Tips
Severe Internal Chatter or Size Taper Defects: Verify that the tool tip center height aligns precisely with the lathe spindle rotation centerline (±0.01mm). An off-center tool alters the effective relief clearance, provoking rapid tool nose chipping or harsh rubbing lines along the cavity wall.
Precision Screw Jamming or Thread Stripping: Fine turning swarf generates highly localized frictional heat. Blow out fine micro-dust from the pocket seat before indexing inserts, and periodically apply anti-seize lubricant to the M2.5 screw threads to avoid terminal binding.
Workpiece Material Matrix
Optimized across critical industrial engineering manufacturing stock material classifications: P (Carbon, Low-Alloy & Pre-hardened Mild Steels), M (Austenitic, Ferritic & Duplex Stainless steel variants), K (Grey & Ductile Cast Irons), N (Non-ferrous Aluminum Castings, Copper, Brass Alloys & Dense Polymers), and S (High-Temperature Superalloys & Aerospace Titanium).
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.
