The amount of power sent to the blade makes it capable of cutting hard materials such as metals, fiber glass, masonry, wood and plaster. For people indulged in activities like construction, plumbing, HVAC, electrical jobs, etc. a reciprocating saw is a must have equipment. However, the selection of a reciprocating saw depends on factors such as weight and size of the saw, accessibility, convenience, power supply to the motor, etc.

Buying Guide

There are some important characteristics of a best reciprocating saw that one must know while making a purchase. Considering the characteristics will definitely help in making the right choice.

Corded vs. Cordless

Corded reciprocating saws have a cord attached to it which when connected to the power socket gives power to the blade up to 15 amps. These are best suited when continuous maximum power is required. However, limited cord length and the all-time availability of power generator or outlet are its major drawbacks.

Cordless saws on other hand do not require a power outlet and is not limited by any kind of cord and hence expanding the area of operation. These are not as powerful as corded saws and therefore are suitable for sawing lighter materials.

Shoe adjustment

Shoe adjustment renders a better control over the saw and help in creating fine cuts by stabilizing the saw during its operation and eliminating any kind of unwanted movement.

Orbital maneuverability

Orbital maneuverability makes the saw work in both horizontal and vertical directions, plus it supplies a uniform cutting speed.

Tool less blade replacement

As the name suggests, tool-less blade replacement does not require any tool for changing the saw’s blade making the whole process more commodious, easy and time saving.

Variable speed

Different materials require different and appropriate speed for being cut with accuracy. Not only will it give you a better control while operating the saw but also aid you in sawing the material with convenience and precision.

Auto stop brushes

This feature of the reciprocating saw is a self-executing process that aims at unmanned mechanical halting of the saw in cases when the brushes abrade because of friction and hence safeguarding the motor from any kind of damage.

Metal gear housing

The metal gear housing is an additional protective feature focused on preventing the motor of the saw from sweltering or burning because of extreme and heavy duty usage. This feature aims at providing protection to the motor and durability to the whole saw.

Speed regulation

Speed regulation system maintains and manages the speed of the saw. It ensures that the cutting speed does not decrease during its operation and even if it tends to happen, this feature will regulate and tune the mechanism to provide uniform speed.

Storage case

A storage case is inevitable when you own a reciprocating saw in order to ensure safety and protection against any possible damage or injury. A storage case that comes along with the saw not only safely accommodates the saw but also stores any kind of accessories that the operator may require on the work site.

How to Use a Reciprocating Saw?

There is no point in owning a reciprocating saw until and unless you know how to use it. One needs to understand certain techniques before using the saw in the right manner.

The best blade for the best job

Different kind of blades are required to cut different kind of materials depending on the hardness of the material and the type of cut required.

  1. Coarse blades: Appropriate for cutting wood, plaster, ceiling boards, etc.
  2. Fine blade: Suitable for cutting metals.
  3. Toothless tungsten carbide-coated blade: Perfect choice for cutting ceramic tiles, stones, cast iron, etc.

Grabbing style and focus

Holding the saw in the right way ensures better control and efficiency of operation. One must grab the saw with both hands with one hand grabbing the handle and the other placed somewhere near the front.

Applying the right pressure

The amount of pressure applied on the cutting material should be adequate and balanced. It should neither be too high or too low. Using an old board for finding the right pressure is always recommended.

Start point and end point of cutting

The starting and finishing point both are important while cutting the material. For instance, if you are to saw plastic or metal pipes, it is necessary to make a small cut by carefully placing the blade at the position where you want to cut and then increasing the pace gradually. If you want to saw through a ceiling, closed doors, wooden doors, etc. it is recommended that you initiate the process by initially cutting a hole and then move ahead for sawing. The ending of the cut should always be done precisely and smoothly.

Movement of the body

Down and up motion is advised while sawing the material. However it should be taken care of that too much motion will leave you with uneven and coarse cuts. To ensure that your saw stays stable, place it on the working surface.
