Home-repair expert Brad Staggs provides some basic information about reciprocating saws -- the best hand-tool there is for tearing things down. They also have more constructive uses -- especially for remodeling jobs. Here are some things you should know. - The reciprocating saw (figure A) works by means of a blade (figure B) that moves back and forth very rapidly when you squeeze the trigger. The blade-stroke is generally about an inch to 1-1/4 inches per stroke.
- With the base-plate resting against the adjacent surface (figure C) the teeth of the blade cut quickly into the material you're cutting -- wood, drywall, metal, PVC etc.
- Though they're not really suited for fine precision work -- such as furniture-making and fine woodworking -- for less exacting work, reciprocating saws are extremely handy. They're versatile in that they can be used right-side-up or upside-down (figure D). This makes them handier than circular saws for working in tight or awkward spots.
- Reciprocating saws are available in cordless models, or standard corded ones (figure E).
- Smaller models (figure F) are available for more smaller jobs and working in confined spaces.
- A variety of blade-types are available for reciprocating saws (figure G). Blades with finer teeth are used for cutting through metal, while abrasive blades are designed for cutting through tile. The longer, general-purpose blades can be used for cutting through a variety of materials, from drywall to tree-limbs, lumber or even nails.
- Tip: Be cautious when using a reciprocating saw to cut through a wall in a remodeling project. The blade will not only cut through the drywall, but may accidentally cut into plumbing or wiring underneath (figure H).
Recap: - Reciprocating saws come in corded and cordless models.
- Be sure to get the right blade for the job.
- Reciprocating saws are handy for working in awkward positions -- even upside-down.
