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.
A reciprocating saw is also called a hackzall saw when it accepts both Hackzall and Sawzall style blades. The term reciprocating saw (also oscillating saw) is also applied generically to any saw which cuts with a back and forth motion.
