The very popular Bosch 1590EVSK Jigsaw earns high marks from both professional users and homeowners. Variable speed control, easy blade changing without tools, and constant torque solid state circuitry add to the machine’s convenience and accuracy.
Instead of one detail that’s better, the Bosch provides several innovations over the standard homeowner’s jigsaw. Extra blade guides closer to the work piece stop the blade from flexing under pressure. Even in thick stock, the Bosch cuts an accurate 90 degrees. Operators can set the maximum speed of the blade with a control dial and then choose any speed down to 500 strokes per minute as the running speed. Instead of losing power at lower cutting speeds or under momentary loads, the Constant Response circuit keeps the power level and cutting rate constant.
With the Bosch 1590EVSK’s one-touch blade changing system, even blades too hot to touch can be switched out safely with one hand. The machine ejects old blades automatically — all the operator needs to do is pull a lever and insert a new blade. Even setting the machine base for bevel cuts is a simple operation — release a lever, set the base according to an accurate dial, and lock the base with the lever. Adjustments require no tools. Accurate bevel cuts up to 45 degrees are possible.
The Bosch doesn’t include a dust collection system, but still was rated top value by both Fine Homebuilding and Woodworker’s Journal. Bosch warrants the 1590EVSK Jigsaw for one year.
