Jamb Saw Brands
Jamb saws are definitely a great tool to have in your arsenal. However, this is not a product that is dominated by one or two brands. Many different manufacturers compete with each other well, offer many of the same features, and have similar prices.
Keeping this in mind, it is still important to understand what makes each popular brand of jamb saws stand out. Below, we will explore three of the top jamb saw brands and what makes them stand out from their competition.
CRAIN is an all-purpose manufacturer of various construction and home-improvement related products. Outside of jamb saws, CRAIN manufacturers welding kits, utility knives, carpet rollers, carpet cutters, wall trimmers, toe kick saws (here) and much more.
Jamb saws made by CRAIN are especially known for their durability and efficiency. The CRAIN No. 835 Heavy-Duty Undercut Saw, for example, has the most powerful motor among our best jamb saw selections.
Irwin Tools is a professional-grade hand and power tool manufacturer owned by Stanley Black & Decker. Like many other jamb saw producers, Irwin Tools doesn’t specialize in jamb saws.

Roberts Consolidated Industries
Roberts Consolidated Industries is one of the world’s leading manufacturers of tools and flooring-related products.
Part of its mission as a brand is to constantly create innovative and unique products to address new challenges and problems of the modern world.
Take the Roberts 17076 Jamb Saw for example. Many electric door jamb saws are a lot bigger and heavier than this model. In a product such as an electric door jam saw which needs to reach tough spots, having a little extra portability and space can go a long way.
Factors to Consider Before Buying a Jamb Saw (350)
Before you decide which jamb saw is right for your needs, it’s important that you do some research and understand the many variables that exist. To help you find the best jamb saw possible, here are the top features that you need to keep in mind.
Powered or Manual
Power tools are almost always the preferred option. Unless you’re one of the few people who like the durability or manual tools (e.g. best wood splitting mauls) over power tools (e.g. chainsaws), you’ll be among the majority that will decide to purchase a powered electric jamb saw instead of a manual hand jamb saw.
Although hand jamb saws are a lot more affordable than electric jamb saws, they also are much harder to use. They don’t cut as quickly, as efficiently, or as precisely.
Adjustable Cutting Height and Depth
Having complete control over the placement of your blade and where it cuts will make your jamb saw work much easier. This can only be done if you get a model with adjustable cutting height and depth.
This feature is so popular because it helps you make perfect cuts each time. In order to receive the most height and depth customization possible, you will usually need to get an electric jamb saw with this feature.
Blade Strength and Quality
Usually, people will only use a jamb saw for cutting wood. Although wood is a lot easier to cut than many other materials, the blade you receive in your new jamb saw might not be quite up to par with what you need.
First, check to see that the blade on your model can be easily replaced. Then, make sure that it is made with a strong material like steel. Finally, check to make sure that the blade has teeth if you want it to cut at the highest level of efficiency possible.
The Durability of the Model
Tools are generally expected to last a long time. In order for this to happen, though, they need to be built with strong parts. For jamb saws, it’s important that you look at the material quality outside of the most relevant parts like the blade.
Check to make sure the handle is durable enough to last years of rough use. If it is a powered model, check to make sure that the casing around the blade and engine are made with strong materials. Finally, check to see if there is an included storage case or a manufacturer warranty.
Price of the Model
The most important factor for many people while shopping for just about any consumer product is the price. After all, people like to feel that they are getting a good deal for their money. As we mentioned, a fair jamb saw price can be anywhere between $15 – 500 depending on which features you receive.
How to Use a Jamb Saw
Although it may appear intimidating to a beginner, using a jamb saw is very simple. In most cases, using a power door jamb saw is also very similar to using a hand jamb saw. Here are the basic steps involved in using a jamb saw.
1. Set Your Cutting Line and Depth
The first thing you need to do is pinpoint where your cuts are going to be and how deep they will be. If necessary, use a pencil and mark the line you intend to follow.
2. Check the Cutting Area for Nails
The last thing you need to do before getting started is to ensure that the space you will cut is free from any sort of nails or strong metal objects. That way, you will have no chance of ruining your jamb saw blade and even the entire cutting job as a whole.
Once you have your cutting line, depth, and the space ready, you are ready to go ahead and start sawing. If you are using an electric jamb saw, turn the device on and let it warm up for a few minutes. Then, saw down the line slowly in the direction away from your body.
Ready to Use a Jamb Saw For Your Next Construction Project?
In order to find the best jamb saw, you should start by considering your personal circumstances and budget.
If you are a professional, and not just an average DIYer, it is usually best to get an electric jamb saw model like the CRAIN No. 835 Heavy-Duty Undercut Saw.
Electric jamb saws are more expensive than manual hand jamb saws but are also more efficient and easier to use.
If you are on a budget, or simply don’t want another power tool sitting around, a manual jamb saw option like the IRWIN Tools ProTouch Dovetail Jamb Saw is a great option to consider.
