摘要： An accessory (100) for a power tool (1) includes a body (101) having a mounting portion (120) configured to engage with a mounting device of the power tool (1). The body (101) also includes a working portion (130) that is applied against a workpiece to effect a desired change to the workpiece such as cutting. The accessory (100) also includes a working plate (134) that is fixed to the working portion (130) and cooperates with the working portion (130) to improve the cutting quality of the accessory (100) including providing a precise cut start. The working plate (134) has a hardness that is greater than that of the body (101).

摘要： A circular saw blade (1) includes a disc-shaped base metal (2) having an outer diameter of 200 mm to 500 mm, and first tips (11) and second tips (13) arranged alternately along an outer circumference of the base metal (2). The circular saw blade (1) has a blade thickness (1a) of 0.8 mm to 2.0 mm. The first tips (11) and second tips (13) have cutting edges (11c, 13c) and a pair of chamfers (11f) at both ends of the cutting edges (1 1c,13c). A first groove (12) and a second groove (14) are formed in a flank so as to extend in a circumferential direction of the cutting edges (11c, 13c). The first groove (12) includes a first groove bottom (12e) that is deepest in a radial direction at a position of a first distance (13a) from a thickness center (7c) in a first thickness direction. The second groove (14) has a second groove bottom (14e) that is deepest in the radial direction at a position of a second distance (15b) from the thickness center (7c) in a second thickness direction opposite to the first thickness direction. A sum of the first distance (15a) and the second distance (15b) is 0.35 mm or less.
