Leitz says its EdgeExpert router bits and WhisperCut cutterheads feature high-shear knife geometry which slices through material with ease.  This differs from traditional tooling which utilizes a “chiseling” action, that can damage both the material and the tool, the company says. Leitz adds the high-shear design drastically reduces cutting force, while optimizing quality and greatly enhancing tool productivity and durability.  With little increase in tooling costs, you get much greater productivity, Leitz says.
