When standard tube brushes fall short, industrial professionals turn to the Double Spiral Tube Brush. Known for its robust construction and high filament density, this tool is the "heavy-duty" sibling of the traditional twisted-in-wire brush.

At Shanghai Longguang Industrial Brush, our abrasive tube brushes are engineered to tackle the most stubborn burrs and deposits in cylindrical workpieces. In this article, we’ll explore why the "double spiral" design is a game-changer for your production line.

What Makes the "Double Spiral" Different?

Most consumer-grade tube brushes use a single-stem, single-spiral design. However, for industrial power-driven applications, the Double Stem, Double Spiral construction is preferred.

• Double Stem (4 wires): Provides extreme rigidity, preventing the brush from bending or snapping under high RPM.

• Double Spiral: Features two layers of abrasive filaments. This increases the "brush face" density, ensuring more contact points per rotation.

• Abrasive Infused Nylon: Unlike plain wire, our filaments are infused with Silicon Carbide (SC) or Aluminum Oxide (AO), allowing them to act like flexible files.

Primary Industrial Applications

1. CNC Machining & Cross-Hole Deburring

After drilling intersecting holes in hydraulic manifolds or engine blocks, sharp burrs often remain inside. The double spiral design ensures that even at high speeds, the brush maintains its shape to effectively clean the "intersections" without changing the bore geometry.

2. Boiler & Heat Exchanger Maintenance

In HVAC and power generation, tubes often develop thick scale or rust. The aggressive cutting action of a double spiral abrasive brush removes these deposits 30% faster than standard single-spiral brushes.

3. Thread Cleaning

Internal threads can trap slag or metal chips. The high density of a double spiral brush allows it to reach deep into the thread roots to ensure a clean, smooth fit for bolts and fittings.

Technical Specifications: Standard Series

Choosing the right size is essential for brush life and performance. We offer a wide range of sizes with Silicon Carbide (SC) 120# as our standard abrasive grit.

Pro Tip: For best results, always use the brush in a clockwise direction to prevent the twisted wire from unraveling.

The LG Advantage: Quality You Can Trust

Why settle for generic brushes? Shanghai Longguang provides:

• Customizable Grits: Choose from 60# to 600# grit depending on your surface finish requirements.

• Durable Stem Wire: We use heavy-duty galvanized or stainless steel stem wires to resist corrosion.

• Precision Manufacturing: Our brushes are balanced to reduce vibration in CNC and handheld power tools.

Conclusion

The Double Spiral Abrasive Tube Brush is more than just a cleaning tool; it is a high-performance consumable that ensures your parts meet strict quality standards. Whether you are deburring a manifold or descaling a pipe, the double-spiral construction offers the durability and aggression needed for the job.
