The Miniature Silicone Polishing Bullet 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 pointed bullet heads conform slightly to the contours of your piece. The 13 x 20mm profile provides a elongated contact surface area for fast leveling, while the tapered ogive tip paths smoothly along narrow curves, allowing individual creators to eliminate fire-scale, level casting lines, and polish metal shanks with optimal rotary control.

Key Product Features

• Flexible Pointed Bullet Geometry: Features a wide 13mm diameter paired with an extended 20mm working length, combining flat side-walls for surface smoothing with a tapered nose tip for blending deep 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.
