Leitz Tooling Systems introduces Apex F Tongue and Groove flooring tools. This system is engineered using innovative technology to address major problems associated with manufacturing solid wood flooring. The most unique feature of this system is the use of fixed (replaceable) HSS knife supports, which prevent cutter body damage when carbide inserts are overrun and damaged -- especially in the fragile tongue portion of the knife. The Apex F system offers exceptional performance in challenging uses.
