BEYOND S1607M-SWUBR06 Internal Indexable CNC Turning Tool Holder
1. Product Overview
"Which rigid internal boring bar provides the best chip clearance and stability for small-bore profile turning using 80-degree trigon WBMT or WCMT 0601 inserts?"
The BEYOND S1607M-SWUBR06 is an industrial-grade, right-hand indexable internal boring bar specifically engineered for stable high-precision machining inside confined workpiece bores. Constructed from premium quenched alloy steel, this specialized tool holder features a unique 16mm stepped-down 7mm neck layout to optimize flank clearance and structural stiffness during deep internal profiling where standard straight bars bind or deflect. Designed to anchor standard 80-degree trigon indexable carbide inserts—specifically the WBMT 0601 or WCMT 0601 series—the rigid pocket pocket geometry maximizes the performance of micro-grain substrates and positive-rake chipbreaker styles under heavy material removal rates (MRR). By securely locking the insert, it effectively suppresses high-frequency harmonic chatter, producing tight dimensional tolerances and exceptional surface finishes.
2. Product Core Advantages (Key Features)
- High-Tensile Quenched Alloy Steel (HRC 42-47): Heavy-duty, heat-treated steel structure provides maximum dynamic rigidity, reducing vibration across overhang configurations up to 4xD.
- SWUBR 95-Degree Lead Angle Configuration: Optimized for internal step-profile turning and blind-hole facing, allowing seamless chip evacuation paths and rapid tool retraction cycles.
- Precision Screw-Down Clamping Matrix: Employs a low-profile Torx screw lock system that applies uniform downward seating force, preventing micro-deflection when encountering variable cutting depths.
- Anti-Corrosive Industrial Skin coating: Finished with a smooth black oxide treatment to withstand aggressive chemical water-soluble coolants and intense friction temperatures.

7. Why Choose BEYOND Cutting Systems
BEYOND is dedicated to building structural reliability into high-performance CNC machining workflows. Our S1607M-SWUBR06 boring bars are ground on high-accuracy 5-axis platforms to guarantee the pocket seating angle matches standard ISO positions. This tight manufacturing tolerance minimizes radial tool-tip runout and secures accurate tool center-height positions during automated cell changeovers.
"Finding a solid 16mm bar that necks down perfectly to clear a sub-10mm bore profile is tough. This tool holder works perfectly. Paired with BEYOND WBMT 060102 inserts on alloy steel sleeve parts, and the finish is flawless."
"Sehr stabil. The pocket profile alignment is extremely exact. The screw lock provides precise retention under continuous cuts. Indexing insert edges has zero deviation on center height."
"Excellent chip flow geometry along the neck. Trigon chips break small and blast out of the bore easily. Very safe for automated cycles."
"Centerline runout is virtually non-existent. Rigidity is excellent for small steel bars, keeping tolerances down to microns. Cost performance is exceptional."
"The black oxide coat holds up great against high-pressure water-soluble fluids. Threads don't bind, pocket walls are tough. Highly recommended."
