The Endurance Diamond fingerjoint cutter tool from Peak Toolworks is strong enough to cut through all types of solid wood materials, including wood with knots and defects, the company says. It can be used for softwood, hardwoods, structural and non-structural work. The PCD tool does not wear out when cutting solid wood. The ability to jump from a HSS tool to a PCD tool is a great benefit in terms of profitability due to fewer tool changes, the company says. Reduced and simplified maintenance of the E.D.F.J. system also saves on labor costs.
