Foredom Mounted Brush-Brass Wire 22 Mm Dia. 2.35mm

Description:

Mounted brush-Brass wire 22mm dia. 2.35mm is a high-performance dental laboratory polishing and cleaning tool used primarily for metal surface treatment. The brush features fine, resilient brass wires that provide moderate abrasive strength, allowing dental technicians to efficiently remove oxides, tarnish, casting residues, and surface contaminants from a wide range of dental alloys including cobalt-chromium, nickel-chromium, and stainless steel. With a 22 mm diameter, this brush delivers broader coverage than smaller versions, making it valuable for cleaning full partial denture frameworks, large metal plates, and orthodontic components. Despite its increased size, the brass wires maintain flexibility, giving the brush a controlled yet effective abrasive action that prevents deep scratching or unwanted surface deformation. The 2.35 mm shank ensures compatibility with most dental laboratory handpieces, enabling smooth operation at low to moderate speeds. This brush is particularly useful during the preparatory stages prior to porcelain application on metal-ceramic restorations, as well as before bonding acrylic components to metal substructures. Technicians use it to remove investment residues, clean solder joints, refine clasp surfaces, and texture bonding areas uniformly. In addition to cleaning metal, the brass-wire brush can be used to develop micro-retentive surfaces that enhance adhesion with resins or soft liners. Its corrosion-resistant brass construction ensures durability and stable performance through multiple sterilization cycles. Overall, this brush is an essential tool for dental laboratories that regularly process metal restorations or appliances, offering a balance of efficiency, precision, and gentle abrasion suitable for critical metal-finishing procedures.
