1#-8# 130mm Scroll Jig Saw s Spiral Teeth Kinds Wood Saw s Wire Metal

For thin hardwood up to about 6mm (1/4"), sizes 1# or 2# give the finest kerf and cleanest edge. If your hardwood is 6–12mm thick, step up to 3# or 4# for a better balance of cut speed and edge quality. Sizes 5# and above are better suited to faster cuts in thicker or softer stock where edge smoothness is less critical.

Yes — the spiral-tooth wire construction handles thin sheet metal and aluminum sheet (typically up to about 1–2mm thickness). For harder metals or thicker stock, use a slower saw speed and apply light, consistent feed pressure. Avoid forcing the blade, as excessive heat shortens blade life on metal.

The blades are carbon steel wire, which can surface-rust if stored in high-humidity conditions. Store unused blades in a dry location or a sealed bag with a desiccant packet. A light wipe with a dry cloth after use helps extend blade life. If corrosion resistance is a priority for your environment, contact us to confirm current stock options.

These are 130mm wire-style blades. Check your scroll saw's manual for the accepted blade length and chuck type (pin-end vs. pinless). Most benchtop scroll saws accept 130mm (5") blades. If your machine uses a different length or requires a flat blade, these wire blades will not fit. When in doubt, measure the distance between your upper and lower blade clamps with no blade installed.

If you are trying a new size for the first time, the 1-piece pack lets you test fit and cut quality before committing. The 5-piece pack suits a single medium-length project where you expect to go through a few blades. The 10-piece pack offers the best per-blade value for ongoing scroll saw work or when you regularly cut abrasive materials like MDF that wear blades faster.

Blade life depends on material hardness, saw speed, and feed pressure. In softwood at moderate speed, a single blade can last through several feet of cutting. In MDF, acrylic, or thin metal, expect shorter life due to abrasion and heat. Signs that a blade needs replacing include visible wire kinking, a burning smell, or the blade drifting off the cut line despite correct tension.

These blades are designed for scroll saws and hand-tensioned wire saw frames that accept 130mm wire blades. They are not compatible with standard power jig saw blade clamps, which require flat, T-shank or U-shank blades. If you have a hand-held bow saw or jeweler's saw frame sized for 130mm wire blades, these will fit correctly.
