Belt, disc, spindle & drum · review
The fastest orbit rate on this shelf at 13,500 a minute, on the smallest motor — which is what a detail sander is.
The end of it The right tool for the places the other six cannot reach, with both dust routes published.
Every figure below names its source. Each one is a manufacturer specification read off the listing itself. The judgments are ours.
The highest orbit rate on either half of this shelf, on the smallest motor.
That is not a contradiction. Material removal follows the abrasive’s travel, and a triangular head a tenth the area of a 125 mm (4.92 in) disc has to move much faster to remove anything at all.
Against the DEWALT’s 8,000 to 12,000 on this shelf, 13,500 is the compensation.
It does not make this a stock-removal tool. One point two amps is 138 watts and the pad is small.
Which is the entire job.
A triangular head gets into an internal corner. A contour attachment follows a molding or a spindle. A flat pad does a small panel.
The published OSM100 spindle sander on this shelf solves the inside-curve version of the same problem with drums. The random orbit sanders here do not solve it at all — a 125 mm (4.92 in) disc bridges a hollow and skates over a corner.
What three heads cost is three sets of abrasive and somewhere to keep them.
Both, published, with the port size given — 1-1/4 inches.
A dust box on a detail sander earns its place, because the tool goes where a hose will not follow: up a staircase, into a window reveal, under a cupboard.
What a box does is catch the coarse fraction and pass the fine one into the room, which is the trade the dust-extraction pages in this catalog set out at length.
Publishing the port size is what lets the other option be taken.
A sanding machine is bought once and fed for years.
So the size of the belt, the disc or the sleeve it takes is a bigger decision than the motor: a common size is sold everywhere and cheaply, and an odd one ties the machine to one supplier at whatever price that supplier charges.
The published Scheppach BTS800 page on this shelf is recommended on exactly that ground — it publishes both consumable sizes, and both are the common ones — and the abrasives shelf in this catalog is where the arithmetic lands.
Hook and loop, in the box.
Which is the difference between a tool that works on the evening it arrives and one that waits for an order — and on a detail sander with three head shapes, the sheets are shape-specific, so a general pack will not do.
The abrasives shelf in this catalog is where the next twelve come from.

Because a small pad covers less ground per orbit. Material removal depends on the abrasive's travel, and a triangular detail head a tenth the area of a 125 mm (4.92 in) disc has to move far faster to remove anything at all. Thirteen thousand five hundred orbits a minute against the DEWALT's 8,000 to 12,000 is that compensation. It does not make it a stock-removal tool — 1.2 amps is 138 watts and the pad is tiny — but it is why a detail sander does not feel hopelessly slow in a corner.
Reach, which is the entire job. A triangular head gets into an internal corner; a finger or contour attachment follows a molding or a spindle; a flat pad does a small panel. The published OSM100 spindle sander on this shelf solves the same problem for inside curves with drums, and the random orbit sanders here do not solve it at all — a 125 mm (4.92 in) disc bridges a hollow and skates over a corner. What three heads cost is three sets of abrasive and somewhere to keep them.
Both, and the listing gives the choice explicitly — micro-filtration on board, or a 1-1/4 inch port for a hose. A dust box on a detail sander is genuinely useful because the tool is used in places a hose will not follow: up a staircase, in a window reveal, under a cupboard. The box catches the coarse fraction and the fine fraction goes into the room, which is the trade the dust-extraction pages in this catalog spell out. Publishing the port size is what lets the other option be taken.
