An accessory for oscillating power tools includes an attachment portion with a rear end couplable to an oscillating power tool and a working portion coupled to the attachment portion and extending along a tool axis. The working portion includes a cutting edge arranged asymmetrically relative to the tool axis with a leading tooth disposed at one end of the cutting edge at a first distance from the rear end, a trailing tooth disposed on an opposite end of the cutting edge at a second distance from the rear end that is less than the first distance, and a plurality of intermediate teeth between leading tooth and the trailing tooth, each disposed less than or equal to the first distance and greater than or equal to the second distance from the rear end, the cutting edge slanted at an acute angle to a line perpendicular to the tool axis.

Accessories for oscillating power tools

An accessory for an oscillating power tool includes an attachment portion configured to be coupled to an oscillating power tool and a working portion coupled to the attachment portion and extending generally along a longitudinal axis. The working portion has a generally planar wedge shape bounded at least partially by a rear non-cutting end with a first width, a front cutting edge opposite the rear edge with a second width that is greater than the first width, a first side cutting edge extending from a first end of the rear end to a first end of the front cutting edge at a first angle to the longitudinal axis, and a second side cutting edge opposite the first side cutting edge and extending from a second end of the rear end to a second end of the front cutting edge at a second angle to the longitudinal axis.
