Scroll Saw Blade Tooth Types and Their Differences
If you’ve ever been curious about the various tooth configurations on scroll saw blades, you’re not alone. Selecting the right blade with the appropriate tooth type can significantly influence the quality of your cuts, efficiency, and overall project outcome. Understanding the distinctions helps in choosing the best blade for your specific woodworking or crafting needs.
Types of Blade Ends: Plain End vs. Pin End
- Pin End Blades: These blades feature small pins on each end that lock into dedicated holders on the scroll saw. They allow for quick and straightforward installation and removal, making them ideal for projects requiring frequent blade changes. Pin end blades are generally more robust and come in standard lengths of 3′, 4′, and 5′.
- Plain End Blades: Without pins, these blades are secured using clamps on the saw. They offer a broader variety of tooth configurations and are available predominantly in 5′ lengths. Plain end blades are favored for their versatility and compatibility with different saw models.
Now, let’s explore the various tooth types available to help you select the perfect blade for your project.
Common Scroll Saw Blade Tooth Types and Their Applications
(A) Regular Tooth Blades
These blades feature evenly spaced teeth along the entire length, providing straightforward, reliable cuts. They are suitable for general-purpose woodworking and come in both plain end and pin end options, making them versatile for various projects.
(B) Skip Tooth Blades
Designed for faster cutting speeds, skip tooth blades have teeth with gaps that enhance chip clearance and produce smooth finishes. They are particularly effective for cutting softer materials like aluminum, copper, brass, and bronze, as well as cold-milled rolled steel up to 1/8 inch thick. Available in plain end and some pin end variants, they are popular among hobbyists and professionals alike.
(C) Double Tooth Blades
This type features two teeth grouped together, followed by a flat space to facilitate efficient removal of chips. Double tooth blades cut quickly and deliver clean edges in wood and plastic, making them suitable for high-speed applications where smoothness is desired.
(D) Reverse Tooth Blades
With a skip pattern, these blades have some teeth pointed in the opposite direction, enabling a smooth, splinter-free finish on the cut surface. There are also Double Reverse Tooth blades, which combine the features of regular reverse teeth with double teeth for enhanced cutting performance and finish quality.
(E) Crown-Tooth Blades
This specialized blade features teeth that point both upward and downward, creating a dual-action cutting process. While slower than other types, crown tooth blades produce the smoothest, cleanest edges with minimal splintering. They’re usually available in plain end configurations and can be flipped when worn for extended use.
(F) Spiral Blades
Spiral blades are engineered to cut in all directions, allowing for 360° maneuverability. They are excellent for intricate scroll or fret work where turning the workpiece isn’t feasible. Ideal for bevel cuts, letters, and numbers, spiral blades come in plain and flat end versions for easier installation and secure retention.
(G) Premium Steel Blades
High-quality blades utilize advanced steel alloys for enhanced durability and cutting performance, especially in dense woods. Our PGT (Precision Ground Teeth) plain end blades feature razor-sharp reverse teeth and wide-spaced gullets, delivering straighter, faster, smoother, and more precise cuts. These premium blades are perfect for demanding woodworking applications.
