Things to Consider Before Buying Best Jamb Saws:

Buying a jamb saw must be isn’t a big deal, but choosing the right one needs some research on your part. An unwise or ill-informed choice may ruin your project or make things difficult for you. So, here are a few things that you need to consider before zeroing in on a final product:

Manual or power

Jamb saws can be both manual and electric. While manual jamb saws are very cheap, they aren’t as easy to work with like those that are electrically powered. Using them will require a lot more effort and cuts may not be as precise as a power tool.

If you have a one-time job, a manual jamb saw may be good, but if you are a pro or want to work often, a power tool is an ideal choice.

Blade quality

This is a very important factor for anyone looking to do a clean job. Good quality blades will not only ensure clean cuts but also guarantee that they do not break down under duress. Steel blades are the best choice for the purpose.

Durability

Quality blades aren’t the only thing that you should be concerned about. The product, as a whole, must be durable too. This means that you should look for a product that has a sturdy handle, powerful engine, durable casing, and a long manufacturer’s warranty.

Adjustability

This is an important area of concern for those looking to buy an electric jamb saw since manual models offer limited adjustability. If you are buying an electric model, make sure that you choose one that gives you total control over cutting depth and height. With this adjustability, you will have precise cuts.

How to Use a Jamb Saw?

To get the desired result, it is important that you know how to use your jamb saw. Though it is not rocket science, care must be taken before you use the saw to cut. Adjusting the blade height according to the flooring material is important.

You should also ensure that the depth of the saw blade is a bit more than the jamb. Before you start cutting, make sure that you check the position of the nails.

Nails can hamper your saw blade; so better avoid it. Before cutting, allow the saw to run for a few minutes to control the speed.
