02 Coating Technology

FLATCOAT® DIA Technology

The diamond coating engineered specifically for zirconia dry milling — where every micron matters.

[ COATING TECHNOLOGY ]

Multi-Layer Real Diamond Coating

FLATCOAT® DIA uses Chemical Vapor Deposition to build a multilayer diamond structure combining alternating nano-crystals and micro-crystals. This creates a flatter, more uniform cutting surface than conventional single-layer diamond coatings.

The result: dramatically less chipping on zirconia restorations, reduced friction-generated heat during dry milling, and tool life that outlasts standard diamond-coated burs by a wide margin.

Because the coating surface is smoother, cutting forces stay lower — meaning less stress on your milling machine's spindle and more consistent margin accuracy across the full life of the tool.

Friction Coefficient

Low friction means less heat, less chipping, and cleaner surface finish

Reduced Chipping

The flat diamond surface minimizes micro-fractures at restoration margins — critical for monolithic zirconia and ultra-thin veneers.

Extended Tool Life

Multilayer nano/micro crystal structure resists wear far longer than single-layer diamond coatings, keeping per-unit costs low.

Dry Milling Optimized

Engineered for waterless milling. Low friction coefficient prevents heat buildup that causes zirconia phase transformation.
