WEN 3922 16-inch Variable Speed Scroll Saw with Easy-Access Blade Changes
Blades
while the 3922 uses a standard blade holding system better for pinless blades
This package includes one 15 TPI pinned blade, one 18 TPI pinned blade, and one 18 TPI pinless blade
Loading Blades
I thought the same way at first. You will never get it tight with the thumb screw and finger pressure. You need to use an allen wrench which fits into the end of the thumb screw. It still takes a lot of force but gets easier the more you do it. WEN should be more clear about this but the instructions are not much help. It seems the pitch tolerance on these threads if incorrect making this much harder than it should be. I almost sent my saw back but I think I can fix this on my own. WEN does need to look into this.
This saw uses pinned and pinless blades. Pinned blades are
thicker for stability and for faster assembly. They provide faster
cutting on a variety of materials.
NOTE: When installing pinned blades, the slot on the blade
holder must be slightly wider than the thickness of the blade.
After the blade is installed, the blade tension mechanism will
keep it in place.
TIP: The table insert can be removed during blade changes to
provide more access to the blade holders, but this is not man-
datory. The table insert should always be replaced before using
the saw.
REMOVING THE BLADE
\1. To remove the blade, relieve the tension on it by lifting up the blade tension lever (Fig. 11 – 1). If necessary,
turn the lever counterclockwise to loosen the blade holder further.
\2. Unlock both the front locking knob (Fig. 12 - 1) and back locking knob (Fig. 12 - 2) and open the side panel.
\3. Remove the blade from the blade holders (Fig. 13 - 1).
•
For a pinned blade, push down on the upper blade holder to remove the blade from the upper blade holder
and then remove the blade from the lower blade holder.
•
For a pinless blade, ensure that there is slack in the blade and it is not tensioned. Loosen the thumbscrews
(Fig. 13 - 2) in the top and bottom blade holders and remove the blade from the holders.
INSTALLING THE BLADE
\4. Install the blade on the blade holders (Fig. 13 - 1).
For Pinned Blade:
CAUTION: Install the blade with the teeth pointing downward.
•
Hook the blade pins in the recess of the lower blade holder.
•
While pushing down on the upper blade holder (Fig. 13 -
1), insert the blade pins into the recess of the upper blade
holder.
\5. Push the tension lever down and make sure the blade is properly positioned.
\6. Turn the tension lever clockwise until the desired tension in the blade is achieved.
TIP: A properly-tensioned blade will make a high-C sound (C6, 1047 Hz) when plucked with a finger. A brand-new
blade will stretch when first tensioned, and may require adjustment.
\7. Close the side panel and secure it by locking both the front (Fig. 12 - 1) and back (Fig. 12 - 2) locking knobs.

Benefits of Scroll Saw Blades
- Accuracy and precision. Scroll saw blades are more precise than other types of blades. Whether you’re working on small pieces or need a careful touch to make your material look flawless, a scroll saw blade can deliver. You can be more fine-tuned and accurate when working with one of these blades, meaning you’ll get precise results on your finished project.
- More intricate, artistic cuts. Unlike other types of saws, a scroll saw and its blade is designed for intricate and artistic work. These blades can cut curves, whorls, designs — and you can do just about anything with them. Intricate contours are a standout benefit of a scroll saw blade, giving you the opportunity to create different shapes and objects beyond what your average saw could ever be used for. This gives you increased artistic freedom and better flexibility if you’re hoping to make more design-forward cuts.
- Better finish. Along with their more precise and intricate cutting capability, scroll saw blades deliver a better finished result as they cut. You don’t have to sand down rough or uneven edges as much as you would with other saw styles. The result is a gentler cut that allows you to actually skip some of the finishing work you’d need to perform with other tools. With a scroll saw blade, you’ll get better smoothness and a more truly-finished finish.
- Master new carpentry skills. If you’re hoping to become even more skilled at wielding a saw and performing carpentry work, a scroll saw blade is exactly what you need. This blade can help you improve and refine your skills, as it’s just the right choice for more specialized and detailed cuts. From sloping, elegant curves to sturdy and secure dovetail joints, a scroll saw blade can take your woodworking to the next level (with some practice, of course!).

Types of Scroll Saw Blades
STANDARD TOOTH
As might be expected, standard tooth scroll saw blades are the most common blade type. These blades are general purpose blades with teeth that have a uniform size and shape and are placed evenly one right after another. The teeth are designed to maximize cutting efficiency while simultaneously clearing away sawdust and debris. This style is available in either a low-TPI wood blade design or a high-TPI metal blade design. Although a bit noisy, these blades are good for beginners due to their simple, forgiving design.
SKIP TOOTH
Skip tooth blades are another beginner-friendly design, beating out standard tooth designs in this regard. Like the standard blade, the skip tooth design uses teeth with an identical size and shape, but unlike standard tooth designs, these blades “skip” every other tooth, giving them half the teeth of a standard tooth blade. The lower number of teeth creates a “gullet” between teeth that increases airflow, sawdust removal, and visibility and decreases scorching projects during cuts. On the downside, these blades lack precision compared to other scroll saw blade types.
DOUBLE TOOTH
Double tooth scroll saw blades are very similar to skip tooth saws. Instead of skipping one tooth, these blades feature a gullet large enough to accommodate two teeth. Contrary to what one might think, these blades are not good for beginners as they can be more difficult to handle than most blades due to the uneven tooth spacing. They can easily wander offline with improper application of speed and pressure whether too much or too little. Easily their biggest advantage, these blades create extremely smooth cut surfaces that often need little more than some sandpaper touch up.
REVERSE SKIP TOOTH
Reverse skip tooth blades are “half and half” blades that have a skip tooth pattern on their top half and a reverse skip tooth pattern on their bottom half. These blades reduce splitting and cracking, creating smooth surfaces on both the top and bottom of a project. These blades do tend to wear out quickly and do not clear sawdust as well as other blades. When installing on an at-rest scroll saw, make sure only two or three of the reverse teeth are visible. Trim the blade if necessary. These blades are perfect for cutting plywood, MDF, and similar materials.
PRECISION GROUND
Precision ground tooth (PGT) blades are top-quality blades not to be confused with “precision sharpened” blades. These blades use a skip tooth blade pattern, but each tooth is ground rather than milled, providing PGT blades with amazing performance and long-term edge retention. These blades tend to have a thinner front-to-rear profile than standard blades, allowing them to achieve incredibly precise and intricate cuts. They are incredibly sharp and will cut quickly and well. As such, they require a good bit of practice to master and are a poor choice for beginners.
SPIRAL
Conventional saw blades only cut in a single direction, but as the name implies, spiral blades are definitely unconventional. This design consists of a tightly twisted blade with teeth positioned to face 360 degrees around the axis and oriented to cut on both up and down strokes. These specialty blades have limited applications, but they can make cuts in materials fed from any direction, making rounded cuts a breeze. Unfortunately, this also means that accidentally cutting oneself is a much higher danger. These blades make rough cuts, and they tend to stretch out and lose their shape over time.
CROWN TOOTH
Crown tooth blades are a relatively new design with some unique advantages. This design uses paired teeth with a small gullet between each “crown”. Each crown consists of two roughly triangular teeth, each mirroring the other to form a crown shape. Unlike other blades, crown tooth blades have neither an up nor a down position, making them easy to install. This also means that as the blade dulls, it can be flipped “upside-down” for a “new” blade. This design is also very controllable. While not great at removing sawdust, these blades shine brightest when cutting plastic, plexiglass, and polywoods.

Key Features
ATTACHMENT METHOD
Scroll saw blades fit onto your saw via one of two methods: pinless or pin end. If a blade is a pin end product, it has pins on the ends that hold it into place on your saw. This can improve blade retention and enhance its stability and security. If a blade is pinless, it has no pins — but it can only be used in saws that can accept pinless blades. Make sure to check your saw (or your saw’s owner’s manual) to determine which type is the right fit. Then, you can narrow down your options to blades that feature the correct attachment method.
BLADE THICKNESS
Blade length isn’t too much of a factor for scroll saw blades, as these blades tend to reach only five inches in length. However, blade thickness can make a difference. Thicker blades tend to be tougher, stronger, and longer-lasting. However, they can be less ideal for more intricate jobs. Thinner blades, on the other hand, are a fantastic choice for fine-tuned and highly precise detail work. You’ll want to consider which is best for the job at hand. To determine the thickness of any scroll saw blade, look at the universal number code. A thicker blade has a higher number, while a thinner blade has a lower number.
TPI RATING
All scroll saw blades, like all saw blades, have a TPI rating. TPI stands for teeth per inch — a rating that’s really a measurement of the density of teeth on a particular blade. The higher the TPI rating is (or the bigger the number), the more teeth there are for every inch of the blade’s length. That increased density is great if you’re looking for a slower blade speed and smoother cuts. However, most scroll saw blades only reach a maximum of 10 TPI. If you’re looking for a higher TPI rating, you’ll want to opt for a bimetal blade.
Other Considerations
- Manufacturing Method. When shopping for saw blades, most people pay little attention to how a blade is made. Most scroll saw blades are milled, shaped into a particular profile. For metal cutters and hobbyist woodworkers, these blades are more than sufficient, but for professional carpenters, a ground blade is the only way to go. These blades are ground to a specific sharpness rather than specific dimensions. Precision ground tooth blades are especially sharp, ideal for intricate, efficient cuts.
- Blade Material. A scroll saw’s blade is most commonly made from hardened steel or a milder steel that’s heat-tempered. However, these materials can affect the size — specifically, the thickness — of the blade. If you’re working with thicker materials, you’ll want to make sure you choose a material that’s thick enough and hardy enough to make easy cuts. You’ll also want to decide if you’re working with harder materials other than wood, as that can make a stronger blade material more desirable.
- Pattern Complexity. Make sure to consider what you’re planning to work on, or which pattern you’re hoping to master, as you choose a scroll saw blade. The complexity of your pattern will determine which kind of blade is best for the results you’d like to achieve. More complex or intricate patterns need blades with smaller teeth. Less complex patterns are well-suited for bigger teeth.

Types of Scroll Saw Blades
Essentially, there are two main types of scroll saw blades.
Pinned Blades
Pinned scroll saw blades are larger, wider and better suited to straight, and more basic cuts. They are less agile than the pinless varieties because they are thicker. This greater width which impedes their ability to fit through small drilled holes.
You usually find that older scroll saws use pinned blades, and it’s the pin that adds the thickness to the blade.
Pinned blades are easier to install in the saw because the pins slot into convenient holes. However, for interior cuts, you have to thread the blade through the project and then attach it to the saw. This takes time and can be fiddly.
Pinless
Pinless scroll saw blades are lighter, thinner and more agile. They create intricate curves and finer scrollwork. Jewelers like this variety of blade for its ability to turn on a pinhead.
Pinless blades are a newer design and take longer to install because the ends fit a clamp that holds them in place. Some saws have quick clamping systems to speed up the process, but they are still not as easy to install as pinned blades.
How Do I Choose a Scroll Saw Blade?
There are many considerations when deciding which scroll saw blade works for you.
Teeth Per Inch
The number of teeth on the blade alters the way it performs. A blade with a higher TPI will cut slower because the teeth are smaller and remove less wood or material with each cut. The upside is that you get a super-smooth finish and better quality curves.
Blades with a higher tooth count tend to be thinner and less robust, which makes them prone to snapping.
Thicker blades typically have fewer teeth, making them more durable and able to take more punishment. It also means they can cut more quickly. The flip side is that this faster speed delivers a rougher finish. Moreover, these blades are less agile, so they are better suited to straight cuts and work which requires less finesse.
Blade Type
Standard Blades
Standard blades have teeth spaced an equal distance apart. These blades are typically metal, although it is possible to get them in wood or plastic. Standard blades are excellent for making straight cuts.
Skip-Toothed Blades
Skip-toothed blades are ideal for beginners because they cut slower and produce less heat. It may make them slower when cutting but they are easier to control. The tooth layout is similar to the standard blade, but there is a wider gap between the teeth, which allows for a greater amount of debris removal.
Reverse Skip-Tooth Blades
The teeth on this blade follow the same pattern as the skip-tooth variety except at the base of the blade. Here, they face the opposite direction, hence the reverse name.
This tooth configuration results in less tear out, which is an issue when you are cutting plywood.
Double-Tooth Blade
These blades take their inspiration from skip-tooth blades. However, the difference is that every third tooth is skipped, so that you have two teeth followed by a single tooth-width gap. They are slower than standard and skip-tooth blades but are excellent for detailed work.
Spiral Blades
The teeth spiral 360 degrees around the shaft. They give the user the ability to cut in all directions, making them the perfect choice for cutting tight angles and turns. However, they are less accurate and harder to control, meaning these blades have limited uses.
Crown-Tooth Blades
These blades have teeth in sets of two, with one tooth pointing upwards and the other pointing down. It doesn’t matter which way the blade is mounted as it cuts in either direction.
What Are the Best Brands of Scroll Saw Blades?
There are some fantastic manufacturers of scroll saw blades out there, but we thought we’d focus on three of the best.
Bosch
Robert Bosch founded the “Workshop for Precision Mechanics and Electrical Engineering” in Stuttgart in Germany, in 1886. By 1901, Bosch moved into automotive supplies and developed a reputation for innovation (1).
It now has over 400,000 employees and has a revenue of approximately 78.5 billion euros, making it a global manufacturer.
Olson Saw
Olson Saw started in 1918, founded in Brooklyn, NY, by four members of the Olson family. They are one of the leading makers of band and scroll saw blades in the United States and supply blades to the likes of Makita, DeWALT, Delta and many other leading manufacturers (2).
SKIL
SKIL is another great American brand. Edmond Michel invented the first electric saw in 1924 and formed the Skilsaw Incorporated Company with his business partner, Joseph Sullivan. SKIL has become so synonymous with the circular saw over the years, that it is affectionately known as a skilsaw (3).
