3mm Dark Gray EVE Flexible Acrylic Polishing Rods for Gemstone & Metal Polishing

The 3mm Dark Gray EVE Flexible Acrylic Polishing Rods are precision rotary finishing abrasive pins engineered for preliminary smoothing, seam blending, and scratch removal on gemstones, jewelry metals (gold, silver, platinum, brass), acrylics, and dental prosthetics. Featuring uniformly dispersed coarse-grade abrasive particles held in an elastic acrylic polymer matrix, these flexible polishing rods seamlessly conform to grooves, recesses, and curved surfaces without altering fine details.

Key Features

• Flexible Acrylic Matrix: Resilient bonding material wears evenly to continually reveal sharp abrasive grains, ensuring uniform, streak-free surface preparation.
• Coarse Pre-Polishing Grade (Dark Gray): Designed for preliminary material smoothing, eliminating casting fire scale and tooling marks, and preparing hard surfaces for intermediate polishing.
• Precision Access: Slim 3mm rod profile reaches tight internal corners, prongs, ring galleries, and intricate carved relief channels.
• Rotary Tool Compatibility: Fits standard 3mm pin chucks and collet mandrels used in flex shafts, micro-motors, and rotary handpieces.

Applications

• Jewelry & Metalsmithing: Preliminary cleanup on cast metal surfaces, smoothing ring shanks, bezels, prongs, and detail filigree.
• Lapidary & Gemstone Carving: Initial surface smoothing on carved jade, quartz, agate, and cabochons prior to fine polishing.
