View · Overview

Product overview

The DSPIAE SF-17 uses a 30 mm taper ending at a 1 mm point to direct its etched tempered-glass surface into corners, recesses and the ends of grooves. The point provides access without adding a disposable abrasive coating to the blade. Its single-direction cut produces the equivalent of a 10000–12000 grit sandpaper finish on an already-shaped plastic surface.

  • The main body remains full width for 80 mm before the taper begins.
  • The intended materials are plastic and hard woods; it is not for metal.
  • Wash the etched face with water, using a toothbrush to recover its cutting action.
  • The clear case protects the tempered glass during storage; do not drop or throw the file.

Notes · Q & A

What's the difference between a needle file and a sanding stick?

Needle files are steel, cut faster and hold their shape for tight spots and metal. Sanding sticks are foam or paper-backed abrasive, kinder to plastic and better for smoothing broad, flat surfaces without gouging.

Which grit should I start with on mould lines?

For plastic, start around 400 grit to knock the line back, then refine with 600–800. Coarser than 400 leaves scratches you then have to chase out, so only go lower for resin flash or heavy work.

Should I file wet or dry?

Wet sanding with a drop of water reduces dust and clogging and gives a finer finish, which matters on resin where the dust is best not inhaled. Dry filing is fine for quick metal work and steel needle files.

How do I stop a file clogging with plastic or resin?

Brush it out with a stiff brass brush along the cut direction. For sanding sticks, tap them clean often. Clogged abrasive stops cutting and starts burnishing, which just polishes the high spots rather than removing them.
