Features Of WEN 3921 Scroll Saw

It’s A Flexible Machine

Users can use both pinned and pin-less blades and this can be done with much ease. All you have to do is take the pin from the holder and then turn your blade at 90-degrees. For the pin-less blade, the holder firmly holds the blades to prevent them from getting loose. The speed range is from 400-1600 strokes per minute, this speed isn’t much when compared with other devices but you can achieve a lot of things using this device. The speed is adjustable using the knob that’s at the front of the tool.

LED Illumination

Like most cutting tools, the WEN 3921 Scroll Saw also comes with an LED light attached to it and is movable so that you can adjust it to cast light on the area you want to work. The LED light gives more visibility to ensure that you follow your cut lines smoothly without errors; this is a good feature when it comes to cutting curves.

Set Up

It is really easy to set up the device; some people, however, find the tuning system a little complex because of the insert plate which is not completely flushed with the table. The knob is also below the table, you may have to use 3 hands to set it up, but can be done with only 2 hands when you’re used to it.


The package comes with a toolbox situated on the left side, and it’s attached to the metal sheet, this is for dust extraction.


The WEN 3921 Scroll Saw comes with powerful blades, they are easy to change more especially if you’re using the pinned blades. Replacing the pin-less blades requires more effort. But once you get used to it, it won’t take much of your time. It’s just that you’ll find it inconvenient most of the time.

Table And Insert

The table is large enough to deal with most of the projects you’re dealing with, more especially for beginners. But the insert has 4-nubs on the side, you should use 0 clearance insert whenever possible. A newbie might find it hard to do this. You can, however, find a lot of tutorials that will guide you on how to set up the zero insert.

Dust Blower

WEN 3921 Scroll Saw comes with it a dust blower to help blow away dust particles. The dust blower might not be effective alone until you add an aquarium pump to it which can be attached to base mounting support. If you can set it right it can clear a lot of dust particles out of the way.
