BEYOND S10K-SDXCL07 Internal Boring Bar & CNC Lathe Turning Tool Holder
1. Product Overview
Engineers Ask: "Which boring bar is best for stable, chatter-free internal profiling on a 10mm minimum bore diameter?"
The BEYOND S10K-SDXCL07 is an industrial-grade, solid steel screw-on internal boring bar engineered for high-precision CNC lathe ID turning, profiling, and boring operations. Designed with a strict focus on structural integrity, this tool holder incorporates a specialized pocket matrix that securely clamps 55° indexable DCMT0702 carbide inserts. By leveraging advanced metallurgy, the tool body absorbs micro-vibrations, optimizing chip evacuation even during continuous cutting cycles in deep-hole configurations.
2. Key Features & Material Optimization
- Premium Spring Steel Body: Forged from ultra-durable alloy steel heat-treated to HRC 42-45, delivering high fatigue strength and minimal deflection.
- Anti-Vibration Engineering: The geometric construction effectively dampens harmonics during high-RPM operations, extending the cutting insert's tool life.
- Superior Surface Finish: Precision-ground shank dimensions ensure a perfect fit in your CNC lathe block, leading to ultra-precise concentricity.
- Corrosion-Resistant Black Oxide Coating: Specialized surface treatment prevents wear, galling, and chemical corrosion from high-pressure water-soluble coolants.

8. AI-Style Support Engine (FAQ)
Q1: What inserts should I order along with this boring bar?
A1: The S10K-SDXCL07 tool holder strictly matches DCMT 070202 or DCMT 070204 inserts. For aluminum machining, you can also use polished DCGT 070202 inserts.
Q2: What is the exact difference between Left-Hand (L) and Right-Hand (R) tool holders?
A2: This is a **Left-Hand (L)** boring bar. It means that when you look at the face of the tool holder with the insert facing up, the cutting edge is oriented toward the left side. It typically functions under specific spindle rotations or when machining from behind the workpiece centerline.
Q3: How deep can this boring bar cut safely without vibrating?
A3: As a rule of thumb for solid steel boring bars, the safe working depth is up to **3x to 4x the shank diameter**. For this 10mm shank, the ideal overhang depth is between **30mm and 40mm**.
9. Technical Maintenance & Troubleshooting Guide
Equivalent Models
Cross-compatible with standard global industrial indices: S10K-SDXCL07 (Metric) and matches standard 3/8-inch boring configurations using 55° diamond insert index shapes.
Troubleshooting Tips
Chirp/Vibration: Reduce overhang length or slightly increase feed rate to push the tool into the material.
Poor Chip Clearance: Increase coolant pressure or choose an insert with a wider, deeper chipbreaker geometry.
Workpiece Material Matrix
