3. Material Composition:

• Filament Material: Silicon carbide (SiC) abrasive filament – industrial grade, high hardness

• Handle/Core Material: Steel – double spiral wound construction

4. Key Features:

• High rigidity and stability – double spiral steel core provides excellent torsional strength and prevents brush deformation under heavy load

• High filament density – more abrasive filaments per unit length for aggressive material removal

• Strong deburring performance – silicon carbide grit effectively removes burrs from cemented carbide, hardened steel, and other difficult-to-machine alloys

• Consistent cutting action – abrasive filaments wear evenly, maintaining performance throughout tool life

• No bristle loss or falling off – grit is securely bonded into the filament matrix

• Cost-effective for medium-to-high volume production – longer service life than non-abrasive tube brushes

Note: While silicon carbide is slightly softer than diamond, this brush offers excellent value for applications where diamond abrasives may be over-spec. For the most demanding cemented carbide applications requiring maximum life and efficiency, consider our diamond abrasive version.

5. Applicable Scenarios:

• Deburring of through-holes and cross-holes in cemented carbide materials – ideal for carbide cutting tools, molds, and wear parts

• Heavy oil and grease removal from industrial pipes – hydraulic systems, compressor galleries, and engine oil passages

• Precision metal finishing – surface smoothing and edge radiusing of precision-engineered components

• Internal surface treatment of metal tubes – removing oxide scale and machining marks

• Automotive and aerospace parts cleaning – gearbox housings, valve bodies, and hydraulic manifolds

Frequently Asked Questions (FAQ)

Q1: What is the benefit of a Double Spiral over a Single Spiral tube brush?

A: A Double Spiral (4-wire) brush is much more durable and rigid. It holds more abrasive filaments, which means it cleans faster and lasts longer. It is the professional choice for power-driven applications, whereas single spiral brushes are often relegated to light manual cleaning.

Q2: Can I use these brushes with a power drill or CNC machine?

A: Absolutely. These brushes are designed for power-driven use. The double-stem construction provides the torque resistance necessary for use with electric drills, air tools, and automated CNC machining centers.

Q3: How do I choose the correct brush diameter for my hole?

A: For effective deburring, the brush diameter should be slightly larger (approx. 5% to 10%) than the hole's internal diameter. This "interference fit" ensures the abrasive tips apply constant pressure against the walls of the bore.

Q4: Will this brush change the dimensions of my precision bore?

A: No. Abrasive nylon filaments are designed to follow the contours of the surface. They will remove burrs and improve surface finish without significantly altering the base dimensions or tolerances of the workpiece.

Q5: What is the best grit for removing oxide layers from aluminum tubes?

A: We generally recommend a Medium Grit (#180 - #240) Silicon Carbide for aluminum. It is aggressive enough to strip the oxide layer but fine enough to leave a smooth, weld-ready surface.
