Several studies showed that the tool life of a cutting tool can be increased over 50% rounding the cutting edge to a specific micrometer value as hard materials are brittle and its sharp edges tend to flake and wear quickly. To recognize problems arising from an unprepared cutting edge, there will be a premature failure or machined part surface quality decrease. The end mill will have signs of chipping, material adhesion, coating peeling, and build-up edge.

DLyte is an effective automated process to round cutting edges of end mills, carbide inserts and carbide reamers to specific radius according to the manufacturer requirements and improve at the same time the surface quality of the flute thus allowing a faster chip flow and increased chip volume. The dry electropolishing technology improves the result of current rounding technologies. It overcomes the barriers of abrasive polishing using solid particles to remove material by ion exchange, even in very hard materials as carbide. As it is a non-abrasive treatment it maintains a good balance between smoothness of the flute and edge radius increasing tool life and resulting in less tool wear.

DLyte is able to process cutting tools after coating, thus smoothing tool surfaces and increasing the chip removal rate, tool life and quality of the machined surface.
