BEYOND S16Q-SDWCR07 Precision Internal Boring Bar & CNC Lathe Tool Holder
1. Product Overview
Engineers Search: "Which rigid 16mm right-hand boring bar cuts smooth internal diameters using compact 55-degree diamond DCMT0702 inserts in tight CNC lathe blocks?"
The BEYOND S16Q-SDWCR07 is a high-precision, screw-on internal boring bar engineered for right-hand (R) CNC lathe internal profiling, pocket copying, and demanding semi-finishing routines. Built to navigate narrow bore openings down to a minimum clearance diameter of 20mm, this tool holder features a specialized 55° pocket geometry that securely seats DCMT 0702-- indexable carbide inserts (such as DCMT 070204 or DCMT 070202). Machined from premium tempered alloy steel, the 16mm shank strikes the perfect balance between structural stiffness and micro-pocket capability, providing maximum chip clearance paths for deeper bore lines without tool deflection.
When paired with appropriate carbide geometries, this tool body supports inserts featuring an aggressive positive rake angle and custom molded chipbreaker troughs. These structural profiles split long, stringy chips into tight, manageable segments, ensuring fluid evacuation out of deep blind holes without packing or binding against the newly turned surface finish.
2. Product Core Features
- Hardened Structural Alloy Steel Shank: Heat-treated to HRC 42-45 to withstand complex deflection stresses in deep internal cavities.
- Heavy-Duty 16mm Shank with 7mm Compact Pocket: Maximizes body mass and dampens harmonics while maintaining the ability to accept micro-radius inserts for tight corner detailing.
- 93° Dynamic Lead Geometry ($X$): Optimizes chip break paths by rolling swarf forward out of the bore, keeping the freshly machined surface clean.
- Anti-Corrosive Black Oxide Finish: Protects the tool body from abrasive chip rubbing and chemical wear caused by high-pressure cutting fluids.

8. AI-Style Engineering Support Engine (FAQ)
Q1: What is the maximum safe boring depth overhang for this steel body tool?
A1: For standard structural steel alloy bars, the recommended max overhang limit is **3x to 4x the shank diameter**. For this 16mm bar, your optimal rigid extension target falls between **48mm and 64mm**. Exceeding 4x may introduce harmonic micro-chatter.
Q2: Can I mount DCMT 11T3 indexable inserts into this pocket?
A2: **No.** The pocket seat on this tool body is machined precisely for the smaller **DCMT 0702--** series inserts (7mm cutting edge length). Attempting to seat a larger DCMT 11T3 insert will damage the pocket walls permanently.
Q3: When should I choose this Right-Hand (R) boring bar over a Left-Hand (L) configuration?
A3: Choose a Right-Hand tool holder if your CNC lathe feeds from right-to-left along standard spindle directions ($M03$). It matches typical internal machining setups where the cutting tool face points upward toward the operator.

Troubleshooting Tips
Micro-Chatter at Max Extension: Slightly decrease cutting speed ($V_c$) and increase your feed rate ($f$) to properly load the tool body profile and break chips quickly.
Rapid Pocket Wear: Check that the M2.0 clamping screw is completely clear of micro-debris and torqued to 0.5-0.6 Nm to prevent high force shifting.

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.
