SF-17 Irregular Glass Mirror Polishing File

The DSPIAE SF-17 shaped glass polishing file

A file of tempered glass with a very fine texture and an irregular profile to its working section. The irregular shape has a specific reason: a flat face will not reach into a narrow joint, into a corner or into a concave transition, so it is exactly there that the marks of the previous sanding stay. A shaped profile polishes those stretches out along with the rest of the part.

What the file does and what it does not

It practically removes no material, it only smooths the surface. It is a finishing tool and comes in only after abrasive paper. Against metal, tempered glass does not clog as fast, does not corrode and does not dirty light-colored plastic with rub-off.

How to work with it

• Work with a drawing movement in one direction and without pressure.
• Choose the part of the profile whose shape matches the place, otherwise the file will only bed down on an edge.
• Rinse a clogged face with water and let it dry.
• Glass is brittle; do not drop the file and do not bend it in your hand.

Who it is for

The file will be appreciated by those who finish intricate parts before a gloss coat, that is typically robot figures, car bodies with pressed shapes and models with many separate panels. For large flat faces a file with a flat working section is more suitable.

A shaped file does not replace a flat one, it complements it. Faces and longer edges are finished with a flat working section and this one comes in only where the flat one cannot reach. Do not breathe in the sanding dust from plastic and resin; work with extraction or at least with a respirator.
