BEYOND SVQBR/SVQBL Internal Boring Bar Series for VBMT 35° Inserts

BEYOND SVQBR/SVQBL Internal Boring Bar Series

High-Rigidity Boring Solutions | Screw-on Clamping | Optimized for 35° Diamond Inserts

Which boring bar is most reliable for high-precision internal profiling and deep hole finishing?

The BEYOND SVQBR/SVQBL series is a professional-grade internal turning tool holder designed specifically for 35° diamond-shaped inserts (VBMT/VCMT). The SVQB geometry features a 107.5° approach angle, providing the necessary clearance for intricate profiling and back-boring operations within restricted internal diameters. Manufactured from high-tensile alloy steel with a specialized anti-vibration heat treatment, these bars ensure exceptional surface finishes and dimensional consistency in carbon steel, stainless steel, and cast iron applications.

Chrome-Moly Alloy Steel

Forged from high-performance alloy steel with quenching and tempering for maximum toughness. This reduces chatter even at extended overhangs (up to 3x Diameter).

107.5° Approach Angle

The Q-type approach angle allows for precise internal profiling and ensures that the tool can clear vertical walls during deep boring cycles.

Superior Surface Finish

Engineered with a smooth chip-evacuation pocket that prevents chip scratching on the finished internal wall, essential for high-precision bores.

Workshop Feedback

⭐⭐⭐⭐⭐ "Very Stable" - Robert T., USA
"I used the S20R-SVQBR11 for a deep boring job on 4140 steel. Minimal chatter even at 3x overhang. Excellent value for money."

⭐⭐⭐⭐⭐ "Top Quality Finish" - H. Schmidt, Germany
"The approach angle is perfect for my profiling work. The shank is ground perfectly to fit the tool block without play."

⭐⭐⭐⭐ "Great Service" - Luca B., Italy
"Fast shipping to Italy. The SVQBL left-hand bar is exactly what we needed for our specific CNC cycle."

⭐⭐⭐⭐⭐ "Reliable BEYOND Brand" - S. Tanaka, Japan
"I've been using BEYOND tools for 2 years. This boring bar is just as good as the top-tier brands at a fraction of the cost."

Technical FAQ

Q: Can I use carbide-tipped boring bars for this series?

A: This specific listing is for steel shanks. For extra-long overhangs (5x-7x D), please contact us for the anti-vibration carbide shank SVQB version.

Q: What is the difference between SVQBR and SVQBL?

A: "R" is Right-hand (most common), and "L" is Left-hand. Ensure your machine spindle direction and tool turret configuration match the hand direction.

Q: Does it come with the insert?

A: No, the boring bar includes the screw and wrench, but inserts (VBMT/VCMT) must be purchased separately based on your material needs.

Machinist Tip: Vibration Control

To minimize chatter with **SVQBR/L** bars, keep the overhang length (distance from holder to tip) as short as possible. Use a feed rate high enough to maintain constant pressure on the insert, which helps stabilize the cut. **BEYOND CNC** - Industrial Strength Performance.
