Reciprocating saw reviews
reciprocating saw reviews - A reciprocating saw is an electrical cutting
tool in which the cutting action is accomplished through the push and
pull reciprocating motion of the blade (rather than rotating it).
It is used to cut metal, wood, drywall, plaster, and tubing among other
materials. It is most commonly used in the construction, demolition,
plumbing, window fitting, and electrical work areas. It is also a very
handy tool for any do-it-yourselfer or home repairman. This saw, also
known as a sabre saw, recipro saw, or Sawzall (a trademark of the
[Milwaukee] Electric Tool Company) has a large blade similar to that of a
jigsaw and a handle designed to allow the saw to be used comfortably on
vertical surfaces.
The common design of this saw has a foot at the base of the blade (again
similar to a jigsaw). The user can rest his 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.
The multiple range of designs vary widely in speed, power, and features,
from smaller, less powerful portable, handheld types which are normally
shaped like a cordless drill, to the high-power, high-speed, corded
models. Speed is measured in SPM (strokes per minute), and most new
models all have variable speed, either through trigger sensitivity or
through a dial. With the variable speed trigger, the harder you squeeze,
the faster the blade moves.
The stroke length refers to the distance that the blade travels in one
forward cutting stroke (the standard length is 1-1/8 inches).The
inclusion of an orbital action has become another important feature to
how these saws are used. The action consists in the oscillation of the
traversed reciprocation in an up and down fashion (this is perpendicular
to the motion of the cut) which causes the tip of the blade to move in
an oval pattern, back and forth as well as up and down. This feature is
primarily used for wood, allowing the quickest cuts. Many of the newer
models of recipro saws also come with a tool-free blade changing system,
as well as an electric brake which stops the blade immediately when the
trigger is released.
The term reciprocating saw (or oscillating saw) is also used generically
to refer to any saw which cuts with a back and forth motion. These
include the sabre saw, scroll saw, jig saw, and rotary reciprocating
saw.
