摘要： The invention proposes a tipped circular saw blade (10) comprising a saw body (11) with a peripheral circular region made of a first material, the peripheral circular region having a plurality of slots (12), and a plurality of tips (13) made of a second material, each tip (13) fixed to a respective slot (12) to form a saw tooth (14) defined between an anterior gullet (15) and a posterior gullet (16), each saw tooth (14) having a cutting edge (141). In accordance with the invention, each saw tooth (14) has a leading face (142) defined between the anterior gullet (15) and the cutting edge (141), the leading face (142) having a profile that includes a single curved surface formed by an R radius, the curved surface encompassing the first material and the second material. The invention further proposes a method of manufacturing a tipped circular saw blade (10), the method comprising a step of forming a saw body (11) with a peripheral circular region made of a first material, the peripheral circular region having a plurality of slots (12); a step of joining a plurality of prefabricated tips (13a), made of a second material, to the respective slots (12) of the peripheral region of the saw body (11), obtaining a preliminary tipped circular saw blade (10a); and a step of grinding the preliminary tipped circular saw blade (10a) to form a plurality of saw teeth (14), each saw tooth (14) defined between an anterior gullet (15) and a posterior gullet (16), and having a cutting edge (141) and a leading face (142) defined between the anterior gullet (15) and the cutting edge (141), the leading face (142) having a profile that includes a single curved surface formed by an R radius, the curved surface encompassing the first material and the second material.

摘要： An electric power saw/cutter includes a rotatable saw structure, a rear handle with a switch/speed control, a front handle and a drive unit for rotating the saw structure. The drive unit itself including a saw structure drive arrangement to which the saw structure is attachable, a transmission for driving the saw drive arrangement, an electric motor for driving an input shaft of the transmission, and a support structure for holding/carrying the saw structure drive arrangement, the transmission and the electric motor. The front handle and the rear handle are directly connected to each other to form a handle unit, which unit is resiliently connected to the drive unit, so that vibrations from the saw blade and drive unit will be reduced in the handle unit.

摘要： A hand-held miter saw (1) with an electrically powered circular saw blade (2) serves for cutting a rod (3). The miter saw comprises a table (4) for supporting the rod (3) and a guideway (5) equipped on the table (4) for aligning the rod (3) into a desired miter angle, a bearing (6) with an axis (7) extending parallel with the table (4) and consisting of a piece of tube (8) and a piece of axle (9) pivotally mounted in the tube (8), a first lever (10) connected to the tube (8) of the bearing (6) and a second lever (11) connected to the axle of the bearing (6), a cutting head (12) supporting the spindle (13) of the circular saw blade (2) in positions where the axis of rotation (14) of said spindle (13) is parallel with the axis of the bearing (6), an arm (15) which is formed on the cutting head (12) and attached to the axle of the bearing (6) or pivotally connected to the first lever (10), and a bar (16), which is attached to the tube (8) of the bearing (6) or to the first lever (10) and is supporting the table (4) in such way that the table (4) can turn about a pivot axis of the table (4) so that the guideway forms an angle with the axis (14) of rotation of the saw blade (2). The miter saw (1) has a light and inexpensive structure and can easily be transported to the area where the rod to be cut is located and here easily and rapid be operated when supported only by one or two of the hands of an operator.
