BEYOND S14N-SSKCR09 Boring Bar – 14mm Right Hand Steel Screw Locking CNC Lathe Internal Turning Tool Holder
1. Product Overview
"Which right-hand 14mm boring bar ensures optimum chip evacuation and rigid structural stability for small-bore internal turning with SCMT 09T3 inserts?"
The BEYOND S14N-SSKCR09 represents the definitive industrial standard for a Solid Alloy Steel Right Hand Internal Turning Boring Bar, precision-developed to execute highly consistent internal profiling, boring, and face cycles on modern CNC lathes. Engineered with an ultra-compact 14mm shank diameter and a versatile 160mm overall length, this tool holder delivers an outstanding balance of structural mass and small-aperture accessibility. It acts as a rugged barrier against harmonic micro-chatter during deep internal passes within tight dimensions, ensuring tighter dimensional repeatability across continuous production shifts.
This premium tool holder is meticulously pocket-milled to house standard SCMT 09T3 / SCGT 09T3 square indexable carbide inserts. Incorporating a 75-degree side cutting approach angle, it effectively redirects high radial push deflection into stable axial forces running straight down the longitudinal core of the 14mm alloy steel body. When paired with high-performance positive-ground chipbreaker geometries, the cutting edge splits tough workpiece fibers seamlessly. The specialized orientation of the insert pocket forces instant chip breaking, snapping continuous metal ribbons into compact, light swarf spirals that lift out smoothly from a minimum bore clearance of 18mm, protecting the machined surface from scratching or bird-nesting traps.
2. Product Core Features
- Standard Right-Hand (RH) Precision: Fully optimized configuration for conventional forward spindle directions and standard turret turning paths.
- Vacuum-Hardened Alloy Steel Body: Thermal-treated matrix increases fatigue limits and yields superior dampening characteristics under variable chip thicknesses.
- 75° Taper-Preventing Approach Geometry: Converts radial push back into structural compression load, maintaining extreme boring straightness over small-diameter internal bores.
- Low-Profile Torx Screw Clamping System: Utilizes a highly flush M3.5 screw locking mechanism that completely eliminates bulky top clamps, maximizing clear chip evacuation space in restricted cavities.

4. Product Application Scenarios
The rigid steel composition and popular 14mm right-hand geometry make the S14N-SSKCR09 a versatile asset across production fields:
- Small-Diameter Internal Cylinder Boring: Highly efficient for boring out precision valve sleeves, small pump housings, and custom motorcycle hub components.
- Multi-Step Internal Profiling: The 75° approach angle allows the tool to run continuous profiling paths, interpolating intricate internal steps with high accuracy in tight quarters.
- Medium-Depth Precision Bushings: Extensively deployed across general job shops for machining custom brass/bronze bearings, hydraulic connectors, and specialized pipeline fittings.
5. Compatibility & Equipment Interface
The ground 14mm cylindrical tool body locks firmly into industry-standard metric CNC lathe turrets, static VDI/BMT tool block clamps, and linear gang-tool slides. For workshops operating on imperial standards, it adapts flawlessly inside standard 9/16-inch or 5/8-inch imperial split bushes. This boring bar is fully compatible with premium CNC turning center equipment, including Haas, Mazak, DN Solutions/Doosan, Okuma, Mori Seiki, and automated multi-axis mill-turn cells.
6. BEYOND Premium Substrate & Grade Selection Matrix
Pair your S14N-SSKCR09 boring bar with the appropriate BEYOND insert grade to maximize tool life and master chip breakages:
- BYM11 Grade (PVD Coated Substrate): Structured with micro-hard TiAlN coatings. Optimized to stop built-up edges (BUE) on sticky materials like 304 stainless steel and high-temp titanium alloys.
- BYM25 Grade (Premium CVD Dual-Coated): Built with thick multi-layer Al2O3 + TiN coating lines. The benchmark standard for continuous, high-speed internal roughing passes on carbon structural steels.
- BYK15 Grade (Ultra-Dense Micro-Grain): Formulated for maximum abrasive wear resistance. Custom-engineered for high-speed internal profiling of abrasive grey and ductile cast iron parts.
7. Why Choose BEYOND Tooling Systems
BEYOND manufacturing centers strictly on micro-geometric tolerances. The S14N-SSKCR09 boring bar undergoes rigorous multi-axis automated milling and specialized induction heat treatments. By holding our indexable pocket seats within an ultra-precise ±0.01mm limit, we eliminate carbide micro-movement under heavy pounding. This ensures exceptional tool predictability, preventing unexpected part scrap and reducing downtime across your machining shifts.
