ORO® Miniature Wire Brushes - Brass / Steel / Stainless Steel

The professional-grade pre-mounted rotary wire brushes featuring a comprehensive choice of brass, steel, and stainless steel filaments for heavy-duty de-scaling, localized clearing, and producing texturized satin finishes on fine metals. Eliminating persistent firescale, oxidation coatings, and deep machining tool scars from intricate jewelry castings or watch cases requires resilient rotary instruments. The ORO® Miniature Wire Brush Series provides a highly balanced, bench-ready abrasive solution. Expertly anchored into a centralized metal cap block with an integrated solid shank, these mini wheel brushes eliminate rotational runout, ensuring smooth and uniform surface texturing across flat or deeply recessed workpiece areas.

Advantages

• Factory Pre-Mounted Solid Shank: The brush wheel is structurally staked directly onto a balanced, standard-gauge mandrel shank, ensuring immediate drop-in compatibility with quick-change micromotor handpieces and flexible shaft collets.

• Dual-Plate Mechanical Center Hub: Features a double-sided steel cap compression ring that firmly pinches the roots of individual wire filaments, minimizing fiber fragmentation, shedding, or flaring under dynamic production torque.

• Three Calibration Wire Metallurgy Formats: Offered in distinct technical wire types to support a highly strategic, material-specific finishing line:

  • Premium Fine Brass Wire: Elastic, non-sparking metallic filaments that provide gentle tarnish removal and soft satin finishing without severely eroding delicate sterling silver or gold substrates.

  • High-Tensile Carbon Steel Wire: Rigid, highly aggressive abrasive filaments engineered for fast file-mark stripping, rapid de-scaling, and surface leveling on industrial metals.

  • Hardened Stainless Steel Wire: Corrosion-proof, high-hardness wire loops ideal for scrubbing stainless steel watch casings, white gold structures, and platinum blanks without leaving behind ferrous residues that cause rust.
