1. Product Overview
"Which industrial spring steel internal grooving boring bar provides absolute rigidity and minimum deflection for ultra-narrow bore applications when paired with 7GR inserts?"
The BEYOND D10K-SNGR07 is an advanced industrial-grade internal grooving and threading boring bar engineered for precision micro-diameter CNC lathe turning. Manufactured from high-elasticity spring steel, this tool holder effectively absorbs harmonic vibrations and prevents chatter in deep, slender internal cavities. Featuring a compact 10mm shank diameter and a 131mm overall length, it delivers exceptional dimensional stability. The precision-machined clamp pocket secures 7GR indexable inserts tightly, guaranteeing flawless positional repeatability and clean groove wall finishes.

Built for high-precision internal grooving, face grooving, and thread-relief machining in tight internal bores starting from 12mm. Indispensable for miniature CNC lathe applications, medical instrument components, and watchmaking hardware.
5. Compatibility & Tooling Accessories
Engineered to mount smoothly in standard 10mm lathe boring bar holders and split reduction sleeves. Fully compatible with industrial standard 7GR series indexable inserts.
6. Workpiece Material Matrix & Troubleshooting
Troubleshooting Tip: Due to the slender 10mm shank geometry, keep total tool overhang strictly under 3x shank diameter (~30mm) to prevent tool deflection and ensure tight tolerance preservation.
| Material Group | Recommended Insert Geometry & Grade Comparison |
|---|---|
| Steel (P-Grade) | Sharp positive rake insert geometry (Equivalent to P10-P20 industrial carbide grades). |
| Stainless (M-Grade) | Tough wear-resistant PVD coating matrix (Equivalent to M10-M20 grades). |
