Abstract

An accessory tool for an oscillating tool includes a first metal plate and a second metal plate fixed together to form a body having a first end portion formed by the first metal plate and a second end portion formed by the second metal plate. The first end portion defines a linear cutting edge, and the second end portion defines a drive interface for mounting the accessory tool onto a tool holder of an oscillating tool. The second metal plate includes an overlapping portion that overlaps a portion of the first metal plate. At least one of a first lateral portion and a second lateral portion of a leading edge of the overlapping portion is spaced farther away from the cutting edge than a central portion of the leading edge of the overlapping portion.

First claim

What is claimed is:

1. An accessory tool for an oscillating tool, the accessory tool comprising:
a first metal plate and a second metal plate fixed together to form a planar accessory tool body having a first end portion formed by the first metal plate and a second end portion formed by the second metal plate, the first end portion defining a linear cutting edge, the second end portion defining a drive interface for mounting the accessory tool onto a tool holder of an oscillating tool,
wherein the second metal plate includes (i) a first planar portion that forms the second end portion of the accessory tool body and defines the drive interface, (ii) a second planar portion that includes an overlapping portion that overlaps a portion of the first metal plate and is fixed to the first metal plate, and (iii) a bent portion interposed between the first planar portion and the second planar portion that forms a step down transition between the first planar portion and the second planar portion,
wherein the overlapping portion includes a leading edge that extends across an entire width of the first metal plate,
wherein the leading edge includes (I) a central portion, (ii) a first lateral portion that extends between a first lateral edge of the first metal plate and the central portion, and (iii) a second lateral portion that extends between a second lateral edge of the first metal plate and the central portion,
wherein at least one of the first lateral portion and the second lateral portion of the leading edge of the overlapping portion is spaced farther away from the cutting edge than the central portion, and
wherein the first lateral portion of the leading edge of the overlapping portion extends linearly between the central portion and the first lateral edge, the first lateral portion being angled obliquely relative to the linear cutting edge, and rearwardly from the central portion to the first lateral edge.

2. The accessory tool of claim 1 , wherein the cutting edge is wider than the overlapping portion.

3. The accessory tool of claim 1 , wherein the central portion of the leading edge of the overlapping portion extends linearly across a portion of the width of the first metal plate parallel to the cutting edge.

4. The accessory tool of claim 3 , wherein the second lateral portion of the leading edge of the overlapping portion extends linearly between the central portion and the second lateral edge parallel to the cutting edge and in line with the central portion.

5. The accessory tool of claim 1 , wherein the second lateral portion of the leading edge of the overlapping portion extends linearly between the central portion and the second lateral edge, the second lateral portion being angled obliquely relative to the linear cutting edge, and rearwardly from the central portion to the second lateral edge.

6. The accessory tool of claim 5 , wherein the leading edge has an inverted V-shape.

7. The accessory tool of claim 1 , wherein the overlapping portion includes a trailing edge, the trailing edge extending linearly across the entire width of the first metal plate and being arranged parallel to the cutting edge.
