The Miniature Silicone Polishing Flat Cylinders are professional-grade rotary tools engineered for systematic surface smoothing, edge pre-polishing, and final high-luster finishing of precious metals and alloys.

Formulated with custom abrasive grains embedded within a dense, flexible silicone matrix, these straight-walled cylinders conform slightly to the flat profiles of your piece. The 8x20mm profile provides a long, uniform horizontal contact area for rapid side-surface leveling, while the crisp, flat top edge paths smoothly along perpendicular steps, allowing individual creators to eliminate fire-scale, level casting lines, and true up metal shanks with optimal rotary control.

Key Product Features

• Straight Column Cylinder Geometry: Features an 8mm uniform working diameter paired with an extended 20mm side-wall length, combining a broad linear sweep for face blending with a flat top face for crisp corners.

• Seven-Stage Color-Coded Grit Matrix: Provides a highly visible, color-coded grading system ranging from ultra-coarse black material for rapid stock removal down to ultra-fine yellow compound for bright polishing.

• Integrated Abrasive Bond: Impregnated uniformly throughout the elastic silicone body, ensuring a consistent cutting and polishing rate as the column naturally wears down over time.

• Rigid Straight Metal Mandrel Shank: Secured to a durable metal core that spins true inside your standard jewelry micromotor handpiece or flexible shaft unit.
