Key Features

• 50mm Compact Diameter: Small wheel profile accesses tight corners, recessed areas, pipe ends, and confined workspaces that larger wire wheels cannot reach
• 0.3mm Fine Wire Gauge: Finer wire diameter delivers more controlled, less aggressive cleaning — reducing the risk of surface gouging on lighter gauge metal or finished workpieces
• 6.35mm (1/4″) Shank: Direct-mount shank fits all standard drill chucks for immediate use with a power drill — no angle grinder or bench grinder required
• Brass-Coated Crimped Wire: Brass coating provides corrosion resistance and gives the wire a gold appearance that makes wear monitoring straightforward during use
• 4,500 RPM Rated: Maximum speed aligned with standard drill operating speeds for safe, controlled cleaning at full drill RPM
• Industrial Grade: Built to Tolsen’s industrial series standard for durability under sustained professional use conditions

Application Instructions

1. Insert 6.35mm (1/4″) shank into drill chuck and tighten securely
2. Verify drill speed does not exceed 4,500 RPM
3. Wear appropriate PPE — face shield or safety glasses, gloves
4. Keep bystanders clear — wire fragments can be ejected during use
5. Apply light, even pressure against the work surface
6. Keep the brush moving — avoid dwelling in one area
7. For pipe ends and recesses, guide the brush carefully into the confined area
8. For thread cleaning, run the brush along the thread axis with light pressure
9. Allow the brush to cool periodically during extended use
10. Inspect wire face before each use — do not use if wires are significantly shortened or broken sections are present
