A reciprocating saw is a type of saw in which the cutting action is achieved through a push and pull reciprocating motion of the blade. The term reciprocating saw is commonly assigned to a type of saw used in construction and demolition work. This type of saw, also known as a recip saw, sabre saw, saw zaw or Sawzall (a trademark of the Milwaukee Electric Tool Company) has a large blade resembling that of a jigsaw and a handle oriented to allow the saw to be used comfortably on vertical surfaces. The typical style of this saw has a foot at the base of the blade, also similar to a jigsaw. The user rests this foot against the surface being cut so that the tendency of the blade to push away from or pull towards the cut as the blade travels through its cycle can be countered. == Design == Designs range widely in power, speed, and features, from less powerful portable, handheld models that are usually shaped like a cordless drill, to high-power, high-speed, corded models designed for heavy construction and demolition work. Modern reciprocating saws almost all have variable speed, either through trigger sensitivity or through a dial. Another feature that has become important to the way these saws are used is the inclusion of an orbital action. This action consists of oscillating the traversed reciprocation in up and down fashion (perpendicular to the motion of cut) causing the tip of the blade to move in an oval pattern, up and down as well as back and forth. This feature is primarily for wood, allowing quick cuts. The reciprocating saw is a popular tool used by many window fitters, construction workers and emergency rescue services. Variants and accessories are available for specialized uses, such as clamps and long blades for cutting large pipe. Blades are available for a variety of materials and uses. Common types include metal cutting blades, wood cutting blades, blades for composites, for drywall, and other materials. Many of these blade types have a variety of tooth designs intended for special purposes, such as tree-limb cutting, demolition work, clean cutting, or contaminated materials. Abrasive coated blades are also available for hard materials like tile and stone. The term reciprocating saw (also oscillating saw) is also applied generically to any saw which cuts with a back and forth motion. These include: * Jigsaw * Scroll saw * Sabre saw * Rotary reciprocating saw Powered reciprocating tools are also found in surgery and dental surgery, where they are used in operations that require cutting or grinding of bone.. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「reciprocating saw」の詳細全文を読む スポンサード リンク
