Product Information

Full details

The Dapetz 130mm pin-end scroll saw blades are designed for hobbyists, model makers, and woodworkers who require smooth and precise cutting across wood, plastic, and non-ferrous metals. These blades offer high flexibility and a long service life, making them a reliable choice for intricate craft projects; however, they are specifically engineered for scroll saws that use pin-end attachment systems, limiting their compatibility with flat-clamp or tension-only machines.

Extended Product Information

FAQs

Are these blades compatible with flat-clamp scroll saws?

No, these blades require a pin-end mounting system. They cannot be used in saws that use flat tension clamps.

Can I use these for cutting steel?

These blades are rated for non-ferrous metals (like aluminum or brass) and wood. They are not hardened for cutting ferrous steel.

How many blades come in the pack?

The pack contains 10 individual scroll saw blades.

What is the length of the blade?

The blades are 130mm long.

Why 21 TPI?

A 21 TPI (teeth per inch) count is considered 'fine,' which is ideal for achieving smooth, detailed cuts that do not require significant sanding afterward.

Troubleshooting

Blade snapping frequently during use

Check your machine tension setting; too much tension can cause brittle breakage, while too little allows the blade to flex and bind.

Rough cut edges

Ensure you are using a consistent, light feed rate. Forcing the material through the blade prevents the teeth from cutting clean and causes tear-out.

Blade slipping from the pins

Verify that your saw's pin-end holders are not worn down and that the blade pins are fully seated in the grooves.

Pros and Cons

Pros

  • Excellent for detailed scroll work and complex patterns
  • High tooth count ensures a smooth finish requiring less sanding
  • Easy installation process due to the pin-end mechanism
  • Effective at cutting multiple material types including non-ferrous metals

Cons

  • Compatible only with pin-end scroll saw arms
  • Not suitable for heavy-duty rip cutting
  • May struggle with extremely thick hardwoods due to the blade width

Setup, Compatibility & Care

To install, ensure your scroll saw is powered off and unplugged. Insert the pins into the provided slots on the upper and lower arms, then apply the machine's tension adjustment until the blade is rigid with no lateral deflection. These blades are 130mm long, 3mm wide, and 0.4mm thick. To prolong the life of your blades, always avoid twisting the blade while cutting and store them in a dry environment to prevent oxidation, particularly since they are designed for use with metals.
