The EVE Diacomp Plus Twist RA polishing wheel is a diamond-impregnated composite finishing bur used chairside to pre-polish and high-gloss finish direct composite resin restorations.
Each box supplies 10 twisted polishing wheels on RA (right-angle) mandrels, 5 fine-grit and 5 medium-grit for a complete two-step finishing sequence on a contra-angle handpiece.
Diacomp Plus Twist is EVE’s twisted-fibre composite polisher: a flexible, diamond-coated wheel wound around a metal core so the abrasive surface flexes into occlusal grooves, embrasures and contoured surfaces that a flat disc or rigid point cannot reach.
The RA (right-angle) shank fits standard contra-angle dental handpieces, making it a chairside restorative tool rather than a lab-only accessory. It is designed to remove excess composite and pre-polish restoration surfaces before a final high-shine polish, and is commonly used after finishing burs on anterior and posterior composite fillings, veneers and composite build-ups.
Key Benefits
Two-step grit system
Fine and medium grit wheels in one box cover pre-polishing through to a smoother, closer-to-final finish without changing tools.
Twisted-fibre design
Flexes into contoured and interproximal areas that flat polishing discs and rigid cups miss.
RA fitting
Mounts directly on a contra-angle handpiece for fast chairside use, no separate mandrel needed.
Diamond abrasive surface
Suited to polishing composite and other restorative materials without excessive heat build-up when run within the recommended speed range.
CE-marked, German-engineered
Manufactured to CE 0483 certification and marked “Made in Germany” on the product packaging.
