What is a Jamb Saw and its Use?

Before checking anything else, it is quite important first to understand what exactly a jamb saw is and the purpose it offers. Unlike some other manual saws, jamb saws are usually electric-powered saws. As for their function, they are used to make undercuts around the bottom casings of doors that are called jambs. Hence, these saws made for cutting door jambs are called jamb saws.

Since jamb saws are made to cut under door jambs, they have a perpendicular blade that is quite low. It essentially looks like an angle grinder where the blade is replaced with a saw for cutting in tight spaces under door jambs. Because of the same reason, jamb saws are also known as undercut saws. And these saws are perfect for installing laminate or wooden flooring under door casings. This is quite important if you want to have a clean look.

What are the Different Types of Jamb Saws?

Now that you know that jamb saws are used for dealing with door jambs, you may want to get one for yourself. However, depending on the task that you want to finish, you may want a specific type of jamb saw. This is due to the reason that there are two types of jamb saws out there, which includes:

  • Flush Cutting Jamb Saw: Just per the name, a flush-cutting jamb saw cuts along a flat surface, which is generally the floor. And this type of jamb saw is used to cut door jambs according to the height of your floor.
  • Undercutting Jamb Saw: On the other hand, an undercutting jamb saw is used to cut under the door jambs without damaging the door jambs. This type of jamb saw is useful when you want to install flooring under your door without damaging your doors.

How Does a Jamb Saw Function?

Whether you are using a flush-cutting jamb saw or an undercutting jamb saw, it is highly important to know exactly how a jamb saw functions. This is quite important to ensure that you are cutting jambs properly without damaging your floor or your door jamb itself. To start using a jamb saw, you have to first adjust and set your jamb saw according to your floor thickness. After that, you can turn on the jamb saw and start cutting the door jambs of door casings as required. Once that is done, you can optionally use a chisel to clean up the cut and install the floor around door jambs.

Pros and Cons of Jamb Saws

Even though jamb saws are highly functional for working around door jambs, even jamb saws are not perfect. Like any other power tool, jamb saws have pros and cons. And if you want to pick the perfect power tool for a given job, it is highly important to make sure to keep all of the following pros and cons in mind:

Pros of Jamb Saws:

  • Jamb saws are highly specifically built for cutting around door jambs with high precision. This makes them perfect if you are working with door jambs.
  • When compared with other saw types, only jamb saw can offer clean and precise cuts in tight spaces like around door jambs.
  • While reciprocating saw or oscillating tools can be used around door jambs, using them can be a bit tricky.
  • If you work on industrial applications quite often, adding a jamb saw to your tool kit can be a great idea even though it is only used for specific applications.

Cons of Jamb Saws:

  • In case you wish to use a jamb saw for anything else other than working around door jambs, you will be disappointed because of the highly specific design.
  • Since jamb saws can only be used for a specific application, you’re better off with all in one tools if you are on a tight budget.

Safety Precautions for Jamb Saws

If you are using a power tool like a jamb saw that can cut through wooden door jambs within seconds, then taking some important safety precautions is highly important. While there are a lot of things to keep in mind while handling a power tool like a jamb saw, here are some of the most important ones:

  • Whenever you are using a jamb saw, you need to make sure that nothing gets in the way of the cutting blade. Because depending on what hits the blade, it can completely jam it and even damage the jamb saw itself.
  • Since the cutting blade of a jamb saw rotates at a pretty high speed, it can cause a lot of wood chips and other debris to fly around. Therefore, you should consider using a dust cover paired with a shop vacuum to eliminate the extra dust and debris.
  • As you use your jamb saw more and more, its cutting blade will only get blunt with time. And over a long period of time, this will make cutting things difficult for the jamb saw. This can make your jamb saw to make even more debris and wood chips to fly around. Hence, wearing eye or even face protection is recommended.
