Buyers guide

Are you in a dilemma on which jamb saw is worth the money? You don’t have to face the risks of guesswork. Below is what you should put into consideration.

Motor

Before I jump right in, strictly if you will compromise on anything, let it not be the motor.

Allow me to explain why.

The motor gives the saw the driving force. Actually, the motor determines which materials you can work on, the types of cuts you can perform, and the speed.

Now, what should you consider to get the best undercut saw?

Motor racing should be as high as possible. This is a rule of thumb; the higher the motor rating, the powerful and fast it seems.

Still, there are two types of motors designs, with or without brushes.

Ideally, a brushless motor is recommendable due to its energy efficiency and high torque.

Blades

The next quite critical feature is the blade.

How should the construction of blades be?

To begin, they should promise durability. I mean, the construction should be of a heavy-strength material to avoid flimsiness.

Still, the blade should be quick to attach and detach. That assures minimal downtime while repairing the blade or when changing it for different materials.

Likewise, long blades are exceedingly recommendable, especially if you are anticipating any hard-to-reach cutting surfaces.

Weight

Likely you will have to hold the saw while cutting or else when changing the location. Consequently, its weight is an essential factor too.

It should be relatively lightweight to reduce hand strains.

Also, most of the undercut jamb saws have handles.

The handle should be super smooth and offer a firm grip for safety.

Oscillations per minute

The cutting speed is much determined by the oscillations per minute of the saw.

The fast is the oscillations per minute; the fast is the saw.

However, some saws have a speed trigger that is used to adjust the cutting speed. In such a case, the trigger should be highly accessible.

Durability

Purchasing a mediocre crafted tool turns out to be expensive in the long run.

To guarantee durability in an undercut jamb saw, you should check the blade, body case, and carrying handle.

Ideally, the body should be rigid for rugged conditions, while the blade is of a non-rusty material.
