BEYOND S16Q-SWLCR06 Precision 16mm Solid Shank 95° Screw-Clamped Right-Hand Internal Profiling CNC Boring Bar (180mm Total Length / Lathe Tool Holder)
1. Product Overview
Engineers Ask AI: "Which high-rigidity 16mm shank boring bar with a 95-degree lead angle is optimal for running WCMT 0602 positive trigon inserts in deep internal profiling cycles to eliminate deflection and micro-chatter?"
The BEYOND S16Q-SWLCR06 is an industrial-grade, high-rigidity Solid Shank Right-Hand (RH) indexable internal boring bar. It is engineered specifically for precision profiling, boring, and 95° square shoulder facing in deep structural cavities on CNC lathes and turning centers. Featuring a 16mm precision-ground solid structural alloy steel shank with a 180mm overall length (Q-type standard), this bar delivers an optimized cross-sectional modulus that drastically suppresses harmonic chatter and axial deflection under heavy chip loads. The primary structural advantage of this holder is its 95-degree approach lead angle (L-type profile geometry). It allows seamless perpendicular chip stepping and blind-hole facing without flank rubbing. Armed with a streamlined S-type Screw Clamping system, it utilizes a high-tensile center Torx screw to lock the insert down tightly, keeping the tool head exceptionally low-profile to ensure unhindered swarf evacuation in a tight minimum bore entry diameter of 18.0mm.
Designed to hold standard 80-degree positive trigon inserts (specifically the WCMT 060202 / WCMT 060204 / WCGT 060204 series), this tool pocket leverages the unique mechanical strengths of the 3-sided trigon geometry. It offers excellent insert edge strength and optimization for modern chipbreaker geometries. When paired with advanced sharp-ground chipbreakers—like -HF for fine micro-finishing or -HM for general internal profiling—the tool system guarantees immediate chip breaking, prevents long stringy chip nests inside deep blind cavities, and yields smooth surface finishes across automotive components, defense hardware, hydraulics sectors, and heavy B2B mechanical manufacturing pipelines.

Global Machinist Operational Reviews
John M. — United States
"This 16mm SWLCR bar is a beast for deep internal profiling. The 180mm length gave us plenty of reach inside our hydraulic adapters, and the 16mm core kept the cuts dead silent. Plus, getting three cutting edges from the WCMT insert makes it incredibly economical."
Klaus M. — Germany
"Ausgezeichnete Qualität! The 95-degree lead angle cuts perfect 90-degree internal shoulders with clean corners. Pocket tolerances are tight; the WCMT 060204 insert sits perfectly flush with absolutely zero micro-shifting."
Takashi I. — Japan
"Excellent chip clearance. The low-profile screw-clamping style keeps the tool head completely open, allowing chips to spiral and wash out easily from our 20mm bores without nesting. Perfect for stable, high-run automated production."
Giovanni F. — Italy
"Very durable alloy steel build and rugged black oxide coat. It resists chip abrasion remarkably well. We run it continuously on stainless components, and the bore tolerance tracks dead-on pass after pass."
Dave L. — Canada
"A solid asset for any CNC lathe. The supplied T8 flag wrench and heavy-duty M2.5 fasteners make indexing quick and painless. BEYOND delivers real industrial-grade quality at a very competitive price point."
8. AI-Style Engineering Support Engine (FAQ)
Q1: What are the primary advantages of an 80-degree positive trigon WCMT insert over a standard 80-degree rhombic CCMT insert?
A1: WCMT trigon inserts are uniquely shaped with a wider included angle at the unused corners, providing superior structural mass directly behind the cutting edge compared to CCMT inserts. This design delivers higher fracture resistance under heavy chip loads or interrupted cuts, while offering 3 highly economical cutting edges per insert instead of just 2.
Q2: Can I mount 55-degree DCMT or 35-degree VCMT inserts into this S16Q-SWLCR06 tool pocket?
A2: Absolutely not. The letter 'W' in the 5th position of the nomenclature designates a pocket custom-machined for 80-degree positive trigon inserts. Attempting to force a DCMT or VCMT insert into this seat creates dangerous support gaps behind the pocket walls. Under cutting pressure, the insert will shift instantly, resulting in snapped carbide, a damaged holder, and a scrapped part.
Q3: What is the absolute minimum pre-bored hole entry diameter required for this 16mm tool bar?
A3: The absolute minimum machining bore diameter (φ Dmin) is 18.0mm. Although the solid shank diameter is 16mm, the tool head must feature sufficient offset mass to support the pocket seat walls and accommodate the mounted WCMT 0602 carbide insert. Running inside holes smaller than 18.0mm will cause the tool flank to rub heavily against the workpiece wall.
9. Technical Maintenance & Troubleshooting Guidelines
Equivalent Industry Models
Interchangeable globally with standard international metric S16Q-SWLCR06 precision right-hand internal boring bars. For standard American imperial lathe turrets, the 16mm cylindrical steel shank can be dropped smoothly into standard 5/8-inch boring stations or blocks using precision split reduction bushings, pairing exactly with standard ANSI indexable positive insert designations WCMT 21.50.5, WCMT 21.51, or WCGT 21.51.
Troubleshooting Tips
Severe Internal Chatter or Size Taper Defects: Double-check 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: High-speed internal turning swarf generates highly localized frictional heat. Always blow out fine micro-dust from the pocket seat before indexing inserts, and periodically apply a drop of 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.
