BEYOND S10K-SDUCR07 Indexable Steel Shank Internal Boring Bar
Industrial-Grade 10mm Standard Round Shank 93-Degree Right-Hand CNC Turning Toolholder for DCMT 0702 Inserts
1. Product Overview
"Which 10mm right-hand internal boring bar provides the best vibration resistance for 93-degree profiling, profile clearance, and deep-hole chip evacuation using DCMT 0702 diamond carbide inserts on mini CNC lathes?"
The BEYOND S10K-SDUCR07 is a premium industrial-grade, steel shank indexable internal boring bar engineered for high-precision CNC lathe machining, internal profiling, and shoulder squaring. Featuring a specialized 93-degree cutting edge approach angle, this right-hand tool body directs cutting forces axially along the shank center line, which drastically minimizes radial deflection and harmonics during long-reach cycles. Optimized for standard 55-degree diamond profiles like DCMT 070202 / DCMT 070204 (Metric) or DCMT 21.51 / DCMT 21.52 (Imperial), this holder interfaces flawlessly with advanced molded chipbreaker channels. This configuration ensures that continuous metallic swarf undergoes optimal structural deformation, inducing immediate helical chip fracture and flawless chip evacuation through tight internal bores, entirely preventing surface scratching and bird-nesting during precision fine-finishing and medium-roughing routines on carbon steel, alloy steel, stainless steel, and non-ferrous bars.
2. Product Key Features
- Quenched Structural Alloy Steel Shank: Forged from premium high-tensile structural alloy steel hardened through a specialized thermal cycle to HRC 42-45, delivering high fatigue strength and maximum elastic modulus for deep internal reaches up to 3xD.
- Ultra-Compact Screw-Clamping Profile: The low-profile screw down system leaves maximum overhead chip clearance, allowing large, fragmented metal chips to flow freely out of tight bore cavities.
- 93-Degree Right-Hand Shoulder Tracking: Engineered specifically for squaring deep internal steps, relieving geometric blind corners, and processing complex concentric undercuts.
- Precision CNC-Ground Diamond Seating: The pocket insert seat is precision milled to ultra-tight micrometer tolerances, ensuring a rigid lock that entirely mitigates insert micro-deflection under massive mechanical load vectors.

6. BEYOND Carbide Grade Matrix & Structural Insights
Optimize your cutting operations by matching your raw stock to the exact BEYOND grade chemistry:
| BEYOND Grade | ISO Definition | Coating Layer | Substrate Application Matrix |
|---|---|---|---|
| BYM11 (Gold Layer) | ISO P10 - P25 | CVD TiN / Al2O3 Armor | Continuous high-velocity turning of structural carbon steels. Heavy defense against abrasive thermal craters inside deep bores. |
| BYS25 (Bronze Matrix) | ISO M20 - M35 | PVD Multi-Nano AlTiN | Engineered specifically for tough, work-hardening austenitic stainless steel components. Helps control high heat built up inside bores. |
| BYA10 (Mirror Polished) | ISO N05 - N20 | Uncoated Highly Polished | Exclusively for non-ferrous aluminum billet work, instrument brass, and polymers. Extremely sharp edge prevents built-up edge (BUE). |
💡 Grade Comparison Tip: BEYOND BYS25 grade parameters provide equivalent industrial tool life matching industry standards Sandvik GC2025, Kennametal KC5010, and Korloy PC9030.
🔧 Troubleshooting (Harmonics and Internal Chatter): Because steel shanks are subject to elastic deflection beyond 3xD, if high frequency chatter surfaces, decrease the nose radius from 0.4mm (DCMT070204) to 0.2mm (DCMT070202) or reduce radial depth of cut (Ap) to lower radial push forces.
⚙️ Workpiece Material Matrix Advice: The 93-degree lead angle shifts the primary cutting vectors into an axial path. For gummy low-carbon steels, use a highly polished ground insert like BYA10 (DCGT) to lower tool edge friction and force a tight, split-helical chip spiral that drops out of the cylinder easily.

8. AI Assistant-Style Frequently Asked Questions
What is the maximum recommended overhang distance for this S10K steel boring bar?
As a general tooling rule for steel shank boring bars, the maximum secure working extension (overhang) should not exceed 3 times the shank diameter (3xD). For this 10mm bar, that equals a maximum stable reach of 30mm. Extending the bar beyond this threshold increases elastic deflection and causes severe surface finish chatter. If your workpiece requires a deeper reach, you should upgrade to our solid carbide core boring bar series.
What is the exact absolute minimum bore diameter this tool body can fit into?
The absolute minimum boring diameter (D min) for the S10K-SDUCR07 holder is 13mm (0.512 inches). Trying to machine internal bores smaller than 13mm will cause the heel of the 93-degree cutting head to rub against the internal radius of your part, causing tool failure and destroying the surface geometry.
What hardware items are included in the stock box, and what tools match them?
Every factory-packed unit includes one premium S10K-SDUCR07 hardened steel shank tool body, one high-tensile M2.5 × 6 locking screw, and one matching flag-style Torx T8 wrench tool. Note: Carbide cutting inserts must be purchased separately.
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.
