POWERMATIC® jointers are part of a family of prep tools that also include Powermatic planers. The jointers prep wood boards for glue-up by giving them a straight edge and smooth, even face. The wood pieces are then ready for woodworking with Powermatic mortisers, saws and shapers. These jointers come in various cutting capacities and are powered by 1-phase TEFC motors. They offer a range of convenient features, including extra-long infeed and outfeed tables stabilized on dovetailed ways; dual-quick and fine-tuned adjustments on the infeed table; and worm-gear hand wheels for adjusting fence tilt 45 degrees backward and forward. Most models come with helical-shaped cutter heads with staggered rows of four-sided knives that remove material efficiently and with less noise than straight-knife cutter heads. These jointers with helical cutter heads ensure that stock has the straightest edges and smoothest faces possible.
One innovative line includes Powermatic parallelogram jointers. They have integrated infeed and outfeed tables shaped as parallelograms that make depth-of-cut adjustments much smoother and quicker. The innovative shape of the ground-cast-iron bed of these power tools also maintains more consistent contact between the material and cutter head, enhancing the precision of edge and face surfacing.
Other features of these jointers include non-marring fence inserts and fence tilt with five positive stops forward to 45 degrees. Some come equipped with infeed extension rests to accommodate rabetting and several have three sets of high-speed, heat-treated steel knives instead of a helical design. Most models have ports for hookup to dust collection systems, which are also universal accessories for such tools as Powermatic sanders.
Jointers are one of the classes of industrial-grade woodworking tools that professionals use to prepare stock and boards for subsequent phases of the woodworking process. Cutting tools such as Powermatic saws and finishing tools like sanders benefit from the precision of jointers for providing rough stock that is straight and smooth. Choose Powermatic jointers as the first step in getting woodworking projects done correctly and efficiently.
