WIDE RANGE OF COATING THICKNESS POSSIBLE Depending upon application typical 10 microns (0.0004 in.) to 100

(0.004 in.) microns. Possible: 800 microns (0.032 in.) If coating is used in a sacrificial mode, there is substantial thickness to

wear through so a prolonged component life is possible.

Conclusions of recent external testing

Tool temperature - reduced by 40 degrees

Horse-Power draw - reduced by 49%

CNC Cutting loads reduced by 30-39%

Accelerated Acid Wear Test wear reduction of 50%

EXO saws generate lower cutting forces vs uncoated saws. This translates into:

Lower HP draw

Lower tool temperature

Reduction of friction due to EXO provides reduction of heat, drag and wear significant value driver for a diverse range of wood and metal working products.

PROPERTIES OF

EXO treated tools and components

EXO treated tools and components have excellent lubricityMaterial has an inherently low coefficient of friction. Unique surface topography minimizes contact surface area and hence

leads to lower friction forces.Lesser heat generation than uncoated saws Lower cutting forces and power requirements reduced energy
