Scroll saw blades are available in two types: pin-end and plain-end
Pin-End Blades
Pin-end scroll saw blades have small, round bars (pins) that protrude out from the body of the blade at each end. These pins fit into hook-like receivers on scroll saws that are designed for pin-end blades. The pins usually stick out 1/16", 1/8", or 3/16" from the blade body. Pin-end blades are much faster to change and are ideal for projects that require frequent blade changes. However, they are harder to find, especially as blade specialisation increases, and the pins can make it impossible to thread the blade through very small holes in extra delicate fretwork. Pin-end blades are also thicker and wider than plain-end blades, making them unsuitable for intricate, inside cutting.
Plain-End Blades
Plain-end blades, on the other hand, have square, flat, and plain ends that affix into the jaws of small blade clamps on the scroll saw. This conventional blade-holding design requires more time for blade changes, but plain-end blades are widely available, even for specialty applications. Plain-end blades are also easier to feed through very small fretwork cuts due to their lack of pins. They are the standard for most long-time scroll saw users and are recommended for beginners.
Compatibility
It is important to note that each scroll saw on the market only accepts one type of blade, which is often a determining factor when purchasing a scroll saw. The DeWalt 20-inch Variable Speed Scroll Saw, for example, uses plain-end blades.

The arm lifts up, making it easy to thread the blade through the material for inside cuts. The arm design also keeps the blade perpendicular to the work, reducing over or undercutting.
The DEWALT scroll saw is a powerful and versatile tool, offering quick blade changes and a variable-speed control that allows for speeds ranging from 400 to 1,750 strokes per minute.

Scroll saw blades come in various tooth configurations
Scroll saw blades come in a variety of tooth configurations, each designed for a specific purpose and offering distinct cutting qualities. Here are some of the most common tooth configurations:
- Standard-Tooth Blades: These blades feature teeth that are all the same size and placed right next to each other. They are the most simple design and are suitable for various materials, usually wood and metal. They provide medium-aggression and material clearing capabilities.
- Reverse-Tooth Blades: Reverse-tooth blades have some teeth facing the opposite direction, with spaces between opposite-facing sets of teeth. This design allows the blade to cut on both the up and downstroke, reducing the risk of tear-out and creating very fine, smooth cuts. They are especially suitable for materials prone to tear-out.
- Skip-Tooth Blades: Skip-tooth blades are the most common configuration. They have wider spaces between teeth, which helps clear sawdust and increases cutting speed. However, they produce slightly rougher cuts compared to standard-tooth blades.
- Double-Tooth Blades: Similar to skip-tooth blades, double-tooth blades have spaces between teeth, with two teeth placed back-to-back, followed by a skipped tooth. This configuration results in a slightly smoother cut than skip-tooth blades but at a slightly slower cutting speed.
- Precision Ground Tooth Blades: Precision Ground Tooth (PGT) blades feature teeth that are ground to a high sharpness, providing faster and more aggressive cutting capabilities. They are ideal for making fast, smooth, and straight cuts but may be too aggressive for beginners.
- Crown-Tooth Blades: Crown-tooth blades have teeth pointing up and down, giving them a crown-like shape. They cut on both the upstroke and downstroke, resulting in smooth cuts but at a slower speed compared to other configurations.
- Spiral Blades: Spiral blades are flat blades twisted into a spiral, allowing them to cut in multiple directions. They are useful for projects that are too long to spin on the saw table but can be challenging for cutting straight lines and may require practice to master.
The choice of tooth configuration depends on factors such as project intricacy, material thickness, desired level of control, and cutting speed.

Frequently asked questions
The Dewalt scroll saw uses plain-end blades. Pin-end blades are not compatible with this model.
The standard size of the blades used in the Dewalt scroll saw is #5 or #7. However, the blade size can vary depending on the thickness and density of the wood being cut. For thicker and denser wood, a larger blade such as a #9 or #12 may be more suitable, while for thinner wood, a smaller blade such as a #3 or smaller may be preferred.
Replacement blades for the Dewalt scroll saw can be purchased from local or online scroll saw suppliers, or from hardware stores. Online retailers such as Amazon and Rockler also offer a variety of blade options.
The frequency of blade changes depends on several factors, including the type of material being cut, the complexity of the cuts, and the user's technique. It is recommended to have a sufficient supply of blades as they may need to be replaced multiple times during a project, especially when working with thick or dense wood.
