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.
摘要翻译：视线改善的圆锯。圆锯包括用于围绕轴线可旋转地驱动锯片以切割工件的马达，在锯片的切割平面与工件的表面之间限定的斜角，支撑马达的壳体; 支撑待切割工件上的圆锯的鞋板，鞋板可枢转地连接到壳体以调节斜角; 由房屋支撑的主手柄; 由壳体支撑的辅助手柄; 以及用于指示斜角的指示器。优选地，主把手，辅助把手和指示器被布置成使得在切割位置时，当锯片切割工件并且可以观察指示器时，操作者可以观察锯片。操作者用一只手握住主手柄，另一只手握住辅助手柄。当操作者用另一只手握住辅助手柄时，操作者的另一只手和辅助手柄在锯片切割工件时不会遮蔽操作者对锯片的视图。

摘要： A cutting tool including a base having a turntable mounted thereon for rotation about a vertical axis. The base has a surface including a first detent portion at a predetermined position, and a second detent portion mounted on the turntable and being selectively engageable with the first detent portion to releasably secure the turntable in a predetermined position of angular adjustment relative to the base. The cutting tool also includes a spring biasing the second detent portion against the base surface, and a lever movable with the turntable to move the second detent portion to a withdrawn position allowing angular adjustment of the position of the turntable about the predetermined position of angular adjustment of the turntable relative to the base.

摘要： A cutting tool including a base having a workpiece support surface for supporting a workpiece and an annular, upwardly facing bearing surface. The cutting tool also includes a turntable mounted on the base for rotation about a generally vertical axis. The turntable has a workpiece support surface and an annular, downwardly facing bearing surface. A cutting unit is mounted on the turntable for movement therewith and an annular bearing is mounted between the first and second bearing surfaces. The cutting unit also includes a biasing mechanism for biasing the second surface toward the first surface so that the base workpiece support surface and the turntable workpiece support surface form a smooth continuous upper surface beneath the cutting unit.
