Nova System Carbide Outlasts Noraml Carbide Tooling 5:1. The patented interlocking "blade secure set" eliminates the need for "brazing" the carbide to stell body. Because there is no "brazing" (and therefore the carbide is not submitted to extreme heat), we can use a carbide much harder than C-4.
Nova system Bits Advance through material 3 times faster than conventional bits! Again, the patented interlocking blade set create a cutting tool with virtually no center mass to impede chip clearance, hence, increased clip clearance = increased speed.
