FUJI Wire Brushes represent the peak of Japanese craftsmanship in industrial surface preparation. Designed as heavy-duty cup brushes for angle grinders, these professional tools are engineered to handle the most demanding metalworking jobs where standard brushes fail.
Manufactured to strict Japanese Industrial Standards (JIS), FUJI utilizes a proprietary high-tensile wire formula and advanced knotting technology. Whether you need aggressive material removal for weld slag or flexible action for surface finishing, FUJI brushes outperform standard crimped and twisted brushes in both longevity and consistency.
| Available Sizes | 2.5" (60mm), 3.5" (90mm), 5" (120mm) |
| Wire Material | High-Carbon Steel (Standard) / Stainless Steel (INOX) |
| Knot Patterns | Wave Knot: For flexible, light cleaning. Twist Knot: For aggressive, heavy-duty cutting. |
| Max RPM | 6,800 - 13,000 RPM (Dependent on size) |
| Arbor Size | M10 / M16 Thread |
High-tensile strength wires and advanced anchoring ensure the brush maintains integrity through extended use, resisting wire fatigue.
Precision balancing minimizes vibration. This reduces operator fatigue and protects the angle grinder's bearings.
Available in both Twist Knot (aggressive) and Wave (crimped) styles to handle everything from heavy slag removal to surface polishing.
Engineered to reduce wire breakage and fly-off, meeting strict industrial safety standards.
Wave (Crimped) brushes are flexible and less aggressive, ideal for surface finishing, light rust, and paint removal on thinner metals. Twist Knot brushes are rigid and aggressive, designed for heavy-duty tasks like removing weld slag, thick scale, and heavy corrosion.
No. You should always use a Stainless Steel (INOX) wire brush on stainless steel parts. Using a carbon steel brush will leave behind iron particles that will cause "after-rust" on the stainless surface.
Do not apply excessive pressure; let the tips of the wire do the work. Pressing too hard bends the wires and causes premature breakage. Also, ensure you are running the brush within its recommended RPM range.
Upgrade your surface preparation capabilities with brushes engineered for excellence.
Fuji products are manufactured following strict Japanese standard process requirements. Every wheel is engineered to meet or exceed JIS (Japanese Industrial Standards), such as JIS R 6242 and B 4051. Our core engineering logic prioritizes maximum operator protection by maintaining safety factors and burst speed capabilities that often surpass the highest industry benchmarks.
| Standard Region | Safety Factor (Burst Multiplier) | Safety Logic & Benchmark |
|---|---|---|
| FUJI (High Precision) | > 2.0x | Engineered to exceed JIS requirements for maximum reliability. |
| Japan (JIS R 6242) | 2.0x | Extreme Safety: A wheel rated at 80m/s must withstand a 160m/s burst test. |
| Europe (EN 12413) | $1.73x | Risk Balanced: Provides high safety redundancy for most industrial apps. |
| USA (ANSI B7.1) | 1.5x | Efficiency Focused: Relies on machine guarding and operational procedures. |

When deploying Fuji high-performance tools in overseas markets, ensure that the regional power grid frequency and voltage match the tool specifications. To maintain the superior burst speed safety of Fuji wheels, store abrasives in a dry, temperate environment. Humidity can degrade the resin bond, potentially lowering the wheel’s resistance to centrifugal forces.
