DSPIAE | SF-15

Squared Glass Polishing File

#12000 equivalent — and of the five in this family, the one to buy first

⚠️ Two manufacturer warnings that appear on no other UK listing

It is tempered glass. Do not drop it. DSPIAE state that a crack renders the file useless, and there is no partial use of a cracked one. It comes with its own case for precisely this reason.

Plastic and wood only. Never metal. The working surface is texture worked into the glass itself. Run it along brass, photo-etch or steel and you damage that texture permanently.

📌 The problem this solves

Two marks turn up on every kit ever moulded, and both of them survive ordinary sanding. The first is what is left where the gate was — you nip it, you pare it, you sand it flat, and under a light there is still a faint patch that catches differently from the plastic around it. The second is the parting line, that hairline ridge running down a curved surface where the two halves of the mould met.

Sanding both flat is easy. Getting them invisible is the hard part, because flat is not the same as unmarked. What remains is a field of very fine scratches, too small to see individually and quite big enough to scatter light differently from the surface beside them.

Hobby sandpaper runs out somewhere around #2000 to #2500, which is not fine enough to take that away. This is the tool that finishes the job.

🔧 Why "squared", and why that makes it the one to buy first

There are five files in this family and three of them are exactly the same size, so comparing them on dimensions tells you nothing. The difference is entirely the shape of the working edges, and this is the plain one.

▪ A flat face for surfaces. The broad side does panels, plates and the flanks of anything large. This is where most polishing actually happens and where the shaped files are more awkward than helpful.

▪ Four square edges for corners. A squared section will sit down into a right-angled internal corner and polish it without rounding it off. Rounded or profiled files cannot do that — they leave the corner softer than it started, which on a hard-edged mechanical design is exactly what you do not want.

▪ No specialist profile, and that is the point. The irregular and pointed files in this family exist to reach places this one cannot. This one exists to do everything else, which is most of the work. If you are buying your first glass file, buy the plain one and find out where it stops before you buy a shaped one.

▪ The two jobs DSPIAE actually name. Not "next generation buffing experience" — polishing sprue gate residue and refining mould parting lines. Those are the two marks on every kit, and this is the shape that suits both.

📑 It is not sandpaper that lasts longer — it is a different thing

▪ No grains, no backing, nothing to fall off. Sandpaper is abrasive particles glued to a sheet: the particles blunt, the glue lets go, the sheet clogs, you throw it away. A glass file's cutting surface is texture in the glass. There is nothing bonded on and nothing to wear away.

▪ Clogging is fully reversible. It will fill with plastic dust and start feeling sluggish. That is normal, and DSPIAE's instruction is simply to wash it — rinse the plastic out under the tap and it cuts like new. Worth knowing before you own one, because otherwise the first time it feels slow you will assume it is blunt, and it is not.

▪ It cannot rust. Unlike a steel file left in a cold room over a winter.

▪ So the arithmetic is different. An abrasive you keep buying, against a tool you buy once. That is the honest case for a glass file and it is nowhere in the marketing copy.

▪ What #12000 means. DSPIAE rate the cutting effect as equivalent to #10000–#12000. The finest paper most modellers can buy stops around #2000–#2500, so this is finer than anything available on a backing — which is why it gives a genuine mirror rather than a very smooth matte. It is also why it removes almost no material. This is the last step, not a shaping tool.

🤔 Which file in the family?

MSF-13	90 × 13 × 3 mm — the short one, for tight areas and small parts
SF-15	110 × 13 × 3 mm, squared — this one. Flat faces, square corners. The default
SF-16	110 × 13 × 3 mm, irregular profile — for grinding gaps
SF-17	110 × 13 × 3 mm, sharper and narrower point — for tiny narrow parts
SF-20	165 × 20 × 3 mm, squared — the big one. Most working surface, most to hold

Straight answer: if this is your first glass file, buy this one. It is the plain shape, it handles the flat surfaces and square corners where most polishing happens, and it is the model most people end up using most. Then find out where it stops — and if you keep meeting a gap it will not enter, add SF-16 or SF-17 later. Buying a shaped file first is how you end up with a specialist tool and no general one.

Two exceptions. If nearly all your work is big flat panels, SF-20 is the better first buy — more surface, more to hold on to, faster across an area. And if you build small — miniatures, tiny parts, cramped assemblies — the shorter MSF-13 will suit your hands better than a 110 mm bar of glass.

💡 Getting a mirror out of it

Do the sanding first, properly. This finishes a surface; it does not flatten one. Work up through your grits to around #1500 or #2000, then reach for this. Skipping steps and hoping the glass file will catch up does not work.

Use an edge for corners, the face for surfaces. That is what the squared section is for, and using the face everywhere wastes half the tool.

Stroke in one direction. The texture runs one way deliberately. Following it turns fine scratches into a polish; scrubbing at random angles works against the design.

Barely any pressure. You are refining a surface, not removing material. Pressing harder gains nothing and puts a bending load into a piece of glass.

Wash it the moment it feels slow. Clogged, not blunt. Thirty seconds under the tap and it is back to full effect — and this single habit decides whether you rate the tool.

Case on, every time. Glass loose in a drawer against steel tools is a cracked file waiting to happen.

⚖️ Honest limitations

It is glass and it breaks. One drop onto a hard floor and you own a paperweight.

It removes almost no material. At #12000 it will not shift a nub, level a seam or take down a gate. If that is the problem, you want abrasive, not this.

Plastic and wood only. Metal will ruin the working surface permanently.

A squared file cannot reach into a gap. That is the honest cost of the plain profile and the whole reason SF-16 and SF-17 exist. If your work is full of narrow recesses, this is not the one to start with.

Three files in this family are the same size. The choice between SF-15, SF-16 and SF-17 is profile only, and DSPIAE's documentation of those profiles is thin. If you need a very specific shape, ask us rather than guessing from a photo.

It clogs, and a clogged file feels dead. Not a fault, but if you never wash it you will conclude it has failed.

You may not need one. If you finish matte and never work with gloss, metallics or clear parts, a #12000 polish is invisible on your models. We would rather say that than sell you a tool that lives in a drawer.

Not suitable for children under 8.
