摘要： A circular saw having an improved line-of-sight. The circular saw comprises a motor for rotatably driving a saw blade about an axis to cut a workpiece, a bevel angle being defined between the cutting plane of the saw blade and a surface of the workpiece, a housing supporting the motor; a shoe plate supporting the circular saw on the workpiece to be cut, the shoe plate being pivotably connected to the housing to adjust the bevel angle; a main handle supported by the housing; an auxiliary handle supported by the housing; and an indicator for indicating the bevel angle. Preferably, the main handle, the auxiliary handle and the indicator are arranged so that, in the cutting position, the operator can view the saw blade as the saw blade cuts the workpiece and can view the indicator. The operator holds the main handle with one hand and the auxiliary handle with the other hand. When the operator holds the auxiliary handle with the other hand, the operator's other hand and the auxiliary handle do not obscure the operator's view of the saw blade as the saw blade cuts the workpiece.

摘要： An engine cutter which is simple in structure and low in manufacturing cost. This engine cutter comprises a disk cutter, an air-cooled internal combustion engine for rotating the disk cutter, a safety cover partially encasing the disk cutter, and a dust-trapping portion which is mounted on the safety cover for trapping and discharging dust to be generated from a cutting work by the disk cutter; and is characterized in that only single fan to be driven by the engine is provided not only for generating an air flow for sucking and discharging the dust that has been trapped in the dust-trapping portion but also for generating a cooling air flow for cooling the internal combustion engine.

摘要： A saw blade includes a blade body which defines a first side surface and a second side surface, wherein (i) the blade body has a multiplicity of discrete dimples formed on at least one of the side surfaces, (ii) the blade body is made of metal, and (iii) each of the multiplicity of dimples is formed by a process which includes the step of deforming the metal so as to create an indentation in the side surface in which the dimple is formed. The saw blade further includes a plurality of cutting teeth extending from an edge of the blade body. Moreover, the deforming step includes the step of deforming the metal with pins on a die plate of a punch press.

摘要： A circular saw including a frame, a drive means mounted to the frame coupled to a planar saw blade for rotation about a drive axis within a cutting plane and a base pivotably mounted to the frame about a first axis substantially parallel to the cutting plane and a second axis which is generally substantially parallel to the drive axis. In one aspect, the relative pivotal movement of the frame about the first axis is determined by a trim adjuster including disengageable position locator which is operable to provide a plurality of predetermined discrete engaged positions and a locking means for locking the position of the frame relative to the base over a continuous range of settings. The invention also provides a mounting assembly including a course adjustment means and a fine adjustment means to determine the pivotal movement of the frame about the second axis relative to the base.

摘要： A metal cutting circular saw is provided with an upper blade guard which includes a first sight window disposed in a first side surface and disposed in a plane angularly offset from a plane of the blade. The upper blade guard also includes a second sight window disposed in the second side surface of the upper blade guard. A light window is disposed in a front portion of the perimeter outer surface of the upper blade guard. The upper blade guard is made from metal and the first and second sight windows and the light window are integrally formed as a one-piece member. The saw shoe and lower blade guard are configured to minimize chip spray from contacting a user.
