What We Like

What We Don't Like


This scroll saw has a 9/16-inch stroke length, allowing it to cut approximately 1.4 centimeters as it moves back and forth. It can cut down up to two inches into a variety of materials, including plywood, MDF and plastic sheeting.

The 1.2-amp motor gives you plenty of power to cut through thick materials for an optimal level of efficiency. Measuring 24 by 11 by 13 inches with a weight of around 28 pounds, this saw is fairly light and doesn’t take up a ton of space. It is great for cutting wood but struggles a bit with metal.

The sheer durability of this saw is fairly impressive. It made of ABS plastic and a variety of metal alloys that go particularly well together. The table underneath consists of cast-iron material that will be able to stand the test of time. All of the knobs and switches this saw features are plastic, but they are still very durable. The cast iron table is very sturdy, so you won’t have to worry about the saw moving around while you are working. This makes it easier to get precision results.

One of the best things about this saw is that it has a very user-friendly design. There is a simple mechanism for changing the blades that you shouldn’t have any issues with. It works perfectly with pinless and pinned blades for maximum versatility.


Variable Speed Control

Similar to Dewalt DW7788  with a variable speed dial, this saw has a speed control dial that can be set from 400 to 1600 SPM, allowing you to get the most accurate performance possible. You can quickly and easily adjust the speed according to the material you are working with.

Screw Blade Adapter

The screw blade adapter this saw features will allow you to switch out blades quickly and easily without having to use a tool. This makes working with this saw a lot easier as a whole.

Flex Light

The flex light on this saw gives you maximum visibility at all times so that you can see what you are doing. It can be easily bent and adjusted for the perfect angle no matter what. This can be a very useful feature even if you already have overhead lighting.

Adjustable Air Pump

You will be able to adjust the air pump to clear sawdust away from your work area. This makes it a lot easier to do your cutting work without any frustrating obstructions. It is fairly powerful, so you shouldn’t have to deal with any sawdust covering your design.

16-Inch Throat

The large 16-inch throat of this scroll saw means that you will be able to work with a large piece of material. This can be hugely convenient when you have a particularly wide piece of wood or other material that you need to cut.


Foot Clamp

There is also a hold-down foot clamp that will allow you to keep your material securely in place at all times to reduce the chances of making any mistakes. It is easy to use and does a good job of increasing the accuracy of your cuts.

Onboard Storage

You will have onboard storage for all of your blades so you can keep them organized and in their proper place. This gives you quick and convenient access to any blade you need for the project you happen to be working on at the moment.


Can I use this scroll saw on a tabletop?

While you can use this saw on a tabletop, it is important to clamp it down so it doesn’t move around.

Does this saw feature a foot pedal?

 There is no foot pedal, but you can purchase one as an accessory to use with it.

Is this saw very loud?

You can expect some noise from this saw, but it typically isn’t too loud. It largely depends on the thickness of the material you are cutting.

Can I use spiral blades with this saw?

Yes, you will be able to use spiral blades. They fit in well and can be used for many different types of projects.
