Reciprocating saws first found their life in a product called the Milwaukee Sawzall in 1952. This product line has really grown in the almost 60 years since the birth of the first model. Evolving in both function and flexibility, it has endeared itself to many a workman and weekend do-it-myselfer. It is a powerful electric tool, hand held and able to get into tight places where you would not have access to both sides of the material that you are working on. Here is a brief overview on the characteristics that all Sawzall and their competing products share.
Basis of Operation
Reciprocating Saw
Reciprocating saws are often referred to as oscillating saws. They share a kinship with jigsaws in that they perform a cutting function by rapidly moving back and forth. This is very unlike circular saws that generate lots of torque and must be used on a flat supported surface. Reciprocating saws, though, are not able to product fine cuts or long straight cuts like jigsaws or circular saws, respectably.
The tool is used for a variety of purposes that require the cutting of materials in restricted areas. This can include the cutting in pipes, cutting through wood floors, and even the cutting of lumber containing embedded nails. Care should be taken to use only when the cuts will not show in the final product as they are seldom fine straight cuts.
Different Types
The label of "reciprocating saw" can really be applied to any saw that cuts with a back and forth motion. This would include other power tools in the categories of sabre saws, scroll saws, and jigsaws. These other products, due to their small size and weight, are better fitted for smaller jobs. Only the Sawzall type saws can handle really hefty jobs.
Different Features
One great feature that most saws possess is the ability to rapidly change the large interchangeable blade. This allows the blade to be matched to the type of project quickly. The saws come in both corded and battery operated, the latter being very convenient in out of the way locations. There is a rear handle on most to aid two handed operation while doing vertical cutting. Many saws will also have a pressure foot to help provide stability while cutting, though its use is not required to operate a saw during a cut.
Preventative Thinking
As with any tool, and especially power tools, you should think of safety. These are sharp blades, so you must be careful when the blade is exposed. Wearing goggles during operations is always advised. Using steel-toed boots to prevent injury from falling materials or saw is also a necessity. Use two hands to hold the saw when cutting. Do not use worn blades, but replace them with original Milwaukee Sawzall Blades, if that is the maker of your saw. Lastly, please make sure the item being cut has had its power source disconnected. All these are to prevent injury to you and anyone around you. Do not take these warnings lightly.
Yes, the Work World is a Better Place
Milwaukee did the world a favor by inventing the Sawzall line of heavy duty reciprocating saws. Many other manufacturers have jumped in with other product lines that are just as versatile, but I still tip my hat to the original. Thank you, Milwaukee Electric Tool Company.
