Abstract: A handheld power fret saw (10) having a power fret saw blade (33), which can be clamped releasably between two arms (122, 222), on their ends, that are preferably formed of a U-shaped bracket (22) comprising tubing, the end of one of the arms (221, 222) carrying a handgrip (13), is used especially universally with high precision because the power fret saw (10) can be clipped releasably, in particular in the manner of a bayonet mount, to a sawing table (37), and together with the sawing table (37) the power fret saw (10) forms a portable handheld power tool, which when the sawing table (37) is secured to a workbench or the like serves as a stationary tool.
