Foredom Mounted Brush-Brass Wire17.4mm Dia. 2.35mm

Description:

Mounted brush-Brass wire17.4mm dia. 2.35mm is a specialized dental laboratory instrument designed for metal surface preparation and controlled abrasion within prosthodontics, orthodontics, and general lab workflows. Its fine brass wire bristles provide a balance of firmness and elasticity, making this brush ideal for cleaning casting surfaces, removing oxides, and preparing metal frameworks before soldering, welding, or porcelain application. At 17.4 mm in diameter, the brush offers a convenient medium-size working area suitable for tasks requiring precision, such as refining partial denture clasps, adjusting metal copings, or smoothing orthodontic wire appliances. The brass bristles provide a milder abrasive action compared with steel, reducing the risk of deep scratches while still effectively removing debris, tarnish, and lab residues. The 2.35 mm shank ensures compatibility with standard dental straight or low-speed handpieces, enabling smooth rotational performance and consistent brushing action. This instrument is especially useful during initial metal finishing stages following casting, where technicians must clean investment residue from cobalt-chromium, stainless steel, or titanium components without altering the anatomical details. In addition to metal finishing, the brass-wire brush is used for texturing surfaces to improve bonding strength with acrylics or liner materials. Its controlled abrasive effect allows technicians to roughen surfaces evenly without causing excessive material loss. Brass wires also resist corrosion and maintain flexibility through repeated sterilization cycles, providing long-term reliability. This mounted brush is an essential tool for any dental laboratory that performs metal-based restorative or appliance fabrication, offering dependable surface conditioning and precision-oriented abrasion.
