The Miniature Silicone Polishing Cylinder Points 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 domed cylinder points conform slightly to the contours of your piece. The 13 x 18mm barrel provides a broad contact surface area for fast leveling, while the rounded tip paths smoothly along curved profiles, allowing individual creators to eliminate fire-scale, level casting lines, and polish metal shanks with optimal rotary control.

Key Product Features

• Flexible Domed Cylinder Geometry: Features a wide 13mm diameter paired with an 18mm working length, combining a flat side-wall for broad smoothing with a rounded dome tip for blending tight crevices.

• 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 head 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.
