Tersa™ Knives with NaDia Diamond Coating
RSKZE01 SeriesOur nano-diamond NaDia coating allows you to go 3 or more times as long between changing your Tersa™ knives for planers, jointers, or moulders. With our blades, you get the best of both worlds; the affordability of a HSS knife with a lifespan and cut quality that exceeds carbide. Each order is for a package of 2 knives.
We can fill orders on diamond-coated Tersa™ knives of 100mm, 130mm, 230mm and 310 mm, all with the exact same cut dimensions and set-up as non-treated blades. For custom size orders between 100mm-310mm, contact us through the order form on this page. For heads above 310mm, our stock blades can be combined to fit many common CEL dimensions; by varying the knife stacking between the cutting wings, combinations can achieve a smooth cut without any lines on the planed wood. The exact increase in lineal feet cut before dulling which NaDia coating adds depends on the feed speed and species of wood being cut- typical lifespan increase is in the order of 3 times as long.
NaDia layers the hardness of diamond structures with graphitized carbon molecules which absorb the shock of impact, resulting in a cutting edge with a much lower coefficient of friction- taking far less wear per cut. The coating is a single micron (.001mm) in thickness- so incredibly fine that the dimensions of the cut will match exactly with a non-treated blade.
The only difference is a characteristic rainbow sheen on the surface- the crystalline structure of diamond breaks up the light like a prism. It's applied through an advanced process called Plasma Enhanced Chemical Vapor Deposition which applies the coating at low temperatures, which is important, since heating and cooling metals rapidly can make them more brittle. These HSS M2 blades retain their original material properties, with no extra brittleness or sensitivity.
