PRODUCT DESCRIPTION

DSPIAE | AS-BK15

Aluminium Sanding Plates — 5 mm & 10 mm, 4 Pack, Black

Four rigid 75 mm plates in the two widths that actually reach the parts a normal sanding board cannot touch.

⚠️ Sandpaper is not included — and the numbers matter

These are bare carriers. You supply self-adhesive paper and cut it to the plate width. Before that puts you off, read the section below headed "One pad, four plates, nothing wasted" — the widths in this pack are not arbitrary, and the cutting turns out to be two straight lines with no measuring and no offcuts.

Also worth stating plainly, because one UK listing gets this badly wrong: the plates are 75 mm long, not 150 mm. The "15" in AS-BK15 is a series number, not a dimension.

📌 The problem this solves

You have a sanding board. It is 25 mm wide, it is excellent, and it is completely useless for the part in front of you — because the surface you need to flatten is 6 mm across, and the board is resting on the raised detail either side of it. It bridges. You press harder, and now you have sanded the detail instead of the seam.

Same story in a recessed channel, in the gap between two vents, on the mating face of a small joint part, along a narrow strip between panel lines. The board never touches the thing you are aiming at.

So you fall back to folded paper, which flexes and rounds every edge it touches, or to a file, which cuts fast but leaves its own tooth pattern that you then have to sand out anyway. What is actually needed is the same rigid flat backing you already like — just narrower.

🔧 One pad, four plates, nothing wasted

▪ 10 + 10 + 5 = 25. DSPIAE make their self-adhesive sandpaper in exactly one size: 75 × 25 mm, across the whole MSP and SP range. This pack contains two 10 mm plates and two 5 mm plates. Slice one pad lengthways at 10 mm and again at 20 mm and you have two 10 mm strips and one 5 mm strip — three plates papered from one pad, zero offcuts. Nobody tells you this. It is plainly deliberate on DSPIAE's part.

▪ The 75 mm length already matches. You never cut across the paper, only along it. No measuring, no template, no ruler — lay the pad on the plate, cut down the edge, done.

▪ 2 mm thick, both faces usable. Four plates with two working sides each gives you eight sanding surfaces. That is enough to carry a full grit ladder — #400 through #2000, say — permanently loaded, so a grit change is picking up a different plate rather than peeling and re-sticking mid-job.

▪ Two widths, chosen for real work. 10 mm handles narrow flats, mating faces and strips between panel lines. 5 mm gets into channels and slots where 10 mm still bridges. Between them they cover most of the gap left by a standard 25 mm board.

▪ Forged aluminium alloy, oxidised and sandblasted. Rigid enough that flat stays flat under thumb pressure, with a matt textured finish rather than a slippery polished one. The whole point of a metal carrier is that it does not conform — it makes the part match the plate, not the other way round.

▪ The paper peels off cleanly. DSPIAE's own adhesive is designed to release from these plates without leaving residue, so a plate can be re-papered many times. The plates are the tool; the paper is the consumable.

Straight answer: if you do not already own self-adhesive paper, add some to the same order. DSPIAE's MSP range covers #180 to #2500 in single grits; SP-S01 is the coarse set (#180–#800) and SP-S02 the fine set (#1000–#2500). Other 3M-backed self-adhesive papers will work if you already have them — you are cutting the strips yourself either way.

🤔 Which one do you actually need?

DSPIAE make these plates in three widths and four colours, which is eight products under nearly the same name. The only thing that varies is width:

AS-BK15 — this set	2 × 10 mm + 2 × 5 mm. For reach into narrow places.
AS-BK25	3 × 25 mm plates. Open flat panels and long seams. Takes a die-cut pad with no cutting at all.
AS-25 PRO board	Handled board, 25 × 75 mm face, 90 mm handle, smooth and sawtooth sides. Comfort over long sessions.
AS-25FP / PP / CP blocks	Solid profile blocks — flat, 90° internal angle, curved. Mass and geometry rather than reach.
Carbon fibre boards	Thinner and more flexible than 2 mm aluminium. For recesses these plates still cannot enter.
AT-CSS strip holder	Adjustable curvature, takes user-cut strips up to 9 mm wide. For curves, not flats.

Straight answer: if this would be your first DSPIAE sanding plate, buy the AS-BK25 instead. Three 25 mm plates cover the majority of ordinary flat sanding, the pads go straight on with no cutting whatsoever, and you will use them far more often. Buy the AS-BK15 as your second set, when you have hit the specific wall this pack exists to solve: the board is wider than the part. Buying them the other way round is a common mistake and we would rather you did not make it.

💡 Getting the best out of them

Cut the pad on a cutting mat, not on the plate. Lay the 25 mm pad face up, mark 10 mm and 20 mm along one end, and run a fresh blade down a steel rule. Two cuts. Peel and stick afterwards, not before — cutting through the backing paper while it is already on the metal is how you blunt blades and score plates.

Set the plates up as a ladder and leave them that way. With eight faces you can run something like #400 / #600 on the 10 mm pair and #800 / #1200 / #2000 on the 5 mm pair. Then a grit change is a plate change, which is the whole reason to own four rather than one.

Mark the grit on the bare edge. A dot of paint pen or a strip of tape on the 2 mm edge saves you squinting at four near-identical black plates halfway through a session.

Support the plate along its length. A 5 mm strip of aluminium is stiff, but it is not a joist. Two fingers behind the working area keeps it flat; one fingertip in the middle will let the ends lift and you will dish the surface.

Use the narrow width as a guide, not just an abrasive. Running a 5 mm plate along the inside of a channel keeps the stroke parallel to the walls, which is most of what makes a hand-sanded flat look machined rather than wobbly.

Wipe the plates when you re-paper them. The adhesive is designed to leave no residue, but sanding dust that gets under a fresh strip will telegraph straight through onto the part.

⚖️ Honest limitations

No sandpaper is supplied. On their own these plates do nothing at all. If you order them with nothing to stick on them, they will sit in a drawer.

The paper does have to be cut. It cuts neatly and with no waste, but it is still a job you do at the bench with a blade. The 25 mm plates in the AS-BK25 set need no cutting whatsoever, and if that difference matters to you, buy those instead.

2 mm is thicker than the photographs suggest. More than one buyer has said they expected something thinner. For genuinely tight slots and deep narrow recesses you want a carbon fibre board or a needle file, not these.

Flat work only. No curves, no internal 90° corners, no compound shapes. These are straight rigid plates and they do exactly one thing.

No handle, and the small ones are small. A 5 mm × 75 mm plate held between finger and thumb for twenty minutes is not comfortable, and there is nothing to grip but the plate itself. Fine for detail work in bursts, wrong for sanding a whole panel.

75 mm of working length. Short. On a long seam you will be repositioning constantly.

Easy to lose. Four small black plates on a dark cutting mat. Keep them together in something.

Rigid metal is unforgiving. It removes material quickly and it does not conform to anything. On soft plastic or resin, a heavy hand will flatten detail you meant to keep.
