Pro-source 05011 Twisted Wire Bristle Brush Stainless Steel

Product Description

The PRO-SOURCE 05011 is a stainless steel twisted wire bristle brush designed for cleaning, deburring, and surface preparation in tight bores, tubes, and passages. The brush head measures 1.5 inches long with a 0.1875-inch diameter, and the overall assembled length is 7 inches. Wire filaments are 0.003 inches in diameter, providing a fine, flexible cleaning action suitable for removing light deposits, flux residue, or contamination without damaging bore surfaces. The 0.085-inch galvanized steel shank connects to standard rotary tools, drills, or flexible shaft machines. Trades that routinely service heat exchangers, burner orifices, condenser tubes, or small-bore pipe fittings will find this brush a practical bench and field tool.

This brush is well suited for HVAC, plumbing, and refrigeration service work where narrow-bore cleaning is a regular task. Typical applications include cleaning flue passages, burner ports, condenser or evaporator tube interiors, and threaded fittings before soldering or brazing. The stainless steel fill resists corrosion from flux, moisture, and mild chemicals, making it appropriate for wet or chemically active environments where carbon steel bristles would degrade quickly. Plumbers and HVAC technicians working on copper, brass, or stainless assemblies benefit from the non-contaminating nature of stainless bristles.

Key Features

• Stainless steel fill resists corrosion and contamination in wet service environments
• 0.003-inch wire diameter delivers fine, flexible cleaning action without scoring bore walls
• 1.5-inch brush length covers typical short-bore cleaning tasks in a single pass
• Single spiral construction provides consistent bristle distribution around the full bore diameter
• 0.085-inch galvanized steel shank fits standard rotary tool chucks and flexible shaft drivers
• 7-inch overall length provides reach into recessed ports and heat exchanger passages

Compatibility

Designed for use in bores and passages with an inside diameter of approximately 0.1875 inches. Shank diameter of 0.085 inches is compatible with standard rotary tools, hand drills, and flexible shaft machines that accept small-diameter round shanks.

Installation Notes

Install the shank securely into the tool chuck before operation and confirm the chuck is tightened to prevent slippage at speed. Power down all equipment and isolate any gas, refrigerant, or electrical supply before inserting the brush into active system components. Use appropriate eye protection when operating any wire brush at rotary speeds. Do not exceed the speed rating of the driving tool, and inspect the brush for broken or splayed wires before each use.
