Brown Diamond tools manufactures a complete
range of high quality Polycrystalline Cubic Boron Nitride (PCBN)
tipped tools, Inserts, Reamers etc., for machining ferrous materials.
Our CBN blanks are designed to provide significantly increased
tool life, consistent surface finish and dimensional control.
As a direct result over all part cost can be significantly decreased,
while at the same time, gains in productivity as well as cost
savings in the total manufacturing operation are successfully
achieved.
