The Miniature Silicone Polishing Inverted Cones 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 unique flare-headed inverted cones conform slightly to the geometric angles of your piece. The 10x18mm profile provides an expanding, wide top face paired with a tapered base. This geometry allows you to polish underneath overhanging structures, level flat upper borders, and blend sharp transitions with optimal rotary control.

Key Product Features

• Geometric Inverted Cone Layout: Features an expanding 10mm top diameter that narrows down across an 18mm working length (Model #510), combining a broad face for surface smoothing with a tapered base for undercut clearing.

• 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 cone 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.
