Leitz: Planer Cutterhead
A new addition is an integral version. This is particularly
suitable for processing wood with difficult grain patterns.
According to Leitz, the pre-splitting in the wood is reduced

by an upstream fluted cutting edge, which creates the basis
for a high-quality machined surface.
