DIARC® Diamond, Diadura and Titan coatings are used for cutting tool applications where
high sharpness and excellent wear resistance are needed. The thin and smooth coatings do
not make the cutting edges round. These extremely hard coatings keep the edges sharp
longer, that results in smooth cuts and less dusting even during very long runs.
Thanks to the low deposition temperature (< 100 °C), these coatings can well be deposited
on tools made of heat sensitive materials, such as carbon steel and martensitic stainless
steel, and on tools with adhesive bonded cemented carbide cutting inserts.
Applications for cutting tools coated with DIARC® coatings include
• slitting of packaging and printing cardboard materials
• manufacturing of labels and tags
• manufacturing of packages
• cutting of film, foil and fibre materials
• die cutting of nonwoven products
• cutting of food products
Longitudinal cutting knives and cutting dies
DIARC® Diadura secures long service life of cemented carbide tools used for longitudinal
cutting of food packaging and printing cardboard materials. Due to the long, reliable service
life of the cutting tools, their replacement does not cause extra downtime because they can
be scheduled to coincide with planned maintenance shutdowns.
Diadura is excellent for die cutting applications including, for example, cemented carbide rotary
dies used in the manufacture of nonwoven hygiene products, and the cutting cylinders and cut-
ting die inserts of high-capacity cutters used in liquid and pharmaceutical package applications.
Knives, cutting die bands and flexible thin plate dies
DIARC® Flexo is developed for cutting tools for plastic films, synthetic fibres and foils. It
extends the replacement interval of cutting tools also when cutting highly abrasive materials,
such as polyester film pigmented with TiO2.
Flexo is your choice for coating cutting die rules and flexible thin plate dies when good release
properties together with high wear resistance are needed.
DIARC® Titan is a good choice for cutting tools made of heat sensitive materials, such as
martensitic stainless steel and carbon steel.
