Knotted Wire Cup Brush Twisted

1. Aggressive Deburring Efficiency
The twisted-knot design generates strong cutting force, allowing fast removal of weld spatter, scale, rust and burrs.
Test Result: In a standard 3 mm weld cleaning test, a single brush completes deburring within 30 seconds with a 98% quality pass rate(internal QC test).

2. Superior Wire Retention & Longer Service Life
Each knot is tightly twisted to enhance wire holding strength and reduce wire breakage at high rotations.
Test Result: After a 10,000 RPM equivalent centrifugal test, sampled brushes retained ≥85% of their original pull-out force.
 

3. Material Options for Different Applications
AISI 304/316 Stainless Steel Wire: For stainless steel and corrosion-sensitive workpieces.

High Carbon Steel Wire: Maximum cutting force for fast deburring.

Brass Wire: For softer metals and scratch-sensitive surfaces.

Material certificates (Mill Certificates) are available for every batch.

4. Safe & Stable at High RPM

Each brush is balanced and tested before packaging.
Maximum Recommended Speed: 10,000–15,000 RPM depending on model.

5. OEM & Wholesale Friendly

We offer custom shaft sizes, private label printing, and personalized packaging options to meet your branding needs. With a stable supply capacity for bulk orders, we ensure consistent quality and on-time delivery. Our MOQ starts from 1,000 pcs, and the standard lead time is 25–30 days after PI confirmation.

Our twisted shafted cup brushes undergo strict testing:

Material Verification

Mill certificates for each batch and Chemical composition analysis (C, Cr, Ni)

Performance & Safety Tests
To ensure every brush delivers reliable performance, we conduct a series of strict quality tests, including dynamic balance testing at high RPM to guarantee stable rotation, wire pull-out strength tests to confirm strong wire retention, and knot stability checks to prevent loosening during heavy-duty use. We also run surface roughness improvement tests-such as reducing Ra from 3.2 to 1.4-to verify real, measurable polishing and cleaning results.

Appearance & Dimensional Inspection
We also check every important detail of the brush, including knot uniformity to ensure consistent performance, weld integrity to make sure each joint is strong and secure, and shaft tolerance control so the deviation stays within ≤0.5 mm for stable operation. For bulk orders, we can provide complete PDF QC reports so customers can clearly see all inspection results.
 

This brush is widely used in many metalworking and industrial tasks. It works well for cleaning welds and handling various fabrication jobs. It efficiently removes rust and scale, and is great for preparing surfaces before painting or coating. You can also use it for deburring pipelines, steel plates, and automotive parts. It's a reliable tool for general workshop maintenance as well as construction and industrial engineering. In addition, it is compatible with common drills, angle grinders, and bench tools, making it convenient for different working environments.

When using the metal deburring brush, please follow the installation steps below to ensure safe operation.

Operators must strictly follow the installation procedures when using the wire cup brush with shaft. Always wear a professional helmet and safety goggles to prevent injury from flying steel wires during high-speed rotation.
