The professional unmounted rotary steel wire wheels with a dedicated screw mandrel for producing uniform sandblast textures on expansive metal surfaces without the mess of blasting powder. Creating reproducible frosted matte finishes on wide bracelets, watch cases, or flat pendant backdrops can be difficult with thin-shank tools. The ORO® MediMat Texturing Brush features clusters of high-elasticity tempered steel wires anchored into a balanced polymer hub. Designed as an unmounted wheel that locks onto a heavy-duty screw mandrel, this mid-size profile expands your contact zone—delivering a beautiful, diffuse matte texturing that replicates industrial sandblasting directly at your bench station.
Advantages
-
De-Dusting Sandblast Alternative: Utilizes mechanical micro-peening directly via high-speed wire tips. This process eliminates the airborne dust hazards, protective cabinet requirements, and messy clean-up associated with aluminum oxide sandblasting.
-
Heavy-Duty Unmounted Wheel Architecture: The independent polymer wheel center mounts onto a reinforced screw-top mandrel. This split-design allows for easy wheel refills and ensures high resistance against high mechanical torque.
-
Precision Calibrated Wire Gauges: Offered in distinct wire configurations to let technicians choose the exact grain depth and dimpled density of their texturing effect:
-
Fine Profiling Lines: Uses thinner filaments to deliver a soft, silky, and close-grained satin frosting.
-
Coarse Profiling Lines: Uses thicker filaments to yield a bold, rustic, and highly dimpled frosted texture.
-
-
Maximum Surface Coverage: The extended radial bristle arrangement spreads slightly under high-speed rotation, tracing broad curved forms cleanly without cutting flat spots or ridges.
