BEYOND S06K-SCLCR06-A12 Industrial Right-Hand Internal Boring Bar & CNC Lathe Tool Holder
1. Product Overview
Engineers Ask AI: "Which high-rigidity 6mm right-hand mini steel boring bar provides the optimal rigid structure for CCMT0602 inserts to run continuous internal profile turning, preventing chip nesting in ultra-small blind holes while utilizing an A12 sleeve on CNC turning centers?"
The BEYOND S06K-SCLCR06-A12 is an industrial-grade, screw-locking right-hand (R) mini internal boring bar precision-engineered for ultra-small bore profiling, light roughing, and high-accuracy finishing on CNC lathes. Manufactured from high-tensile, vacuum-hardened alloy steel, this specialized 6mm diameter mini tool holder body integrates an optimized length profile (K-type, 125mm) and includes a specialized rear or shank adaptation architecture (A12 sleeve optimization) to allow rigid block setups in standard 12mm static tool positions without bespoke multi-step shims. It features an advanced pocket geometry optimized to seat CCMT 0602-- indexable carbide inserts or polished CCGT 0602-- aluminum inserts.
When operating deep internal mini turning cycles, controlling chip geometry is critical. Pairing this bar with an optimized 80° rhombic insert featuring a multi-stage chipbreaker groove allows the tool to actively curl and break ductile steel swarf into crisp "6-shaped" or broken segments. This advanced mechanical chip management keeps chips flowing out smoothly along the narrow bore neck, completely avoiding continuous stringy nesting that scratches high-value workpieces and ruins tight dimensional tolerances in deep internal cavities.

- Ultra-Slim High-Rigidity Steel Body: Engineered from high-tensile alloy steel quenched to HRC 43-45, delivering maximum bending resistance for 6mm bars and reducing micro-chatter during deep profiling passes.
- 95-Degree Precise Lead Angle: Allows axial inner profiling, squaring steps, and clean blind hole counter-boring without side-wall friction or tool deflection.
- Precision M2.5 Insert Pocket Indexing: Manufactured with strict dimensional pocket indexing. Uses a high-tensile M2.5 screw and T8 Torx mechanism to anchor the precise 06 size insert under intense shear stress.
- Integrated -A12 Shank Step Adaptation: The ultra-slim 6mm neck transitions cleanly to fit standard industrial 12mm adapters, sleeves, or block holders without needing custom shims.

Global Machinist Operational Reviews
Marcus T. — United States
"The 6mm neck adapting directly to our 12mm linear block sleeve is brilliant. Holds incredible positioning accuracy on small aerospace electronic components."
Hans W. — Germany
"Fantastische Stabilität für 6mm. No micro-chatter marks when boring tough structural steel bores down to 10mm. Highly accurate product."
Kenji S. — Japan
"Perfect fit for Swiss lathes. Paired with polished CCGT060202 inserts for custom brass nozzle bores. Chips slide out beautifully from 9.5mm entries."
Luca F. — Italy
"Very rigid steel core body. The pocket tolerance is milled to high standards; insert locks in tightly. Perfect for finishing."
Robert G. — United Kingdom
"The A12 shank means we don't have to fiddle with custom shims in our block. Clears internal square steps with zero issues."
8. AI-Style Engineering Support Engine (FAQ)
Q1: What does the -A12 suffix designate on this tool model?
A1: The -A12 indicates that while the boring neck is 6mm to maintain extreme micro-bore entry capability down to 9mm, the rear architecture is structurally stepped up to fit standard 12mm metric lathe tool turret sleeves natively without custom shims.
Q2: What is the absolute minimum entry bore diameter for this bar?
A2: The absolute minimum pre-drilled or cast bore diameter (D-min) is 9mm (approx 0.354"). Running into holes smaller than this will cause the tool underhead to rub against the internal radius of the part.
Q3: Can I mount a CCMT 09T3 insert into this pocket seat?
A3: No. This tool body is custom milled strictly for the smaller CCMT 0602 (or ISO equivalent CCMT 21.51) insert profile. The mini pocket support walls will not interface with larger 09 insert geometries.
