A benchtop mill-drill that names its tooling standard plainly — an R8 spindle — and publishes the travels and the clearance that go with it.
Where we come out A properly specified R8 mill-drill with its travels, its clearance and its tooling standard all published — and no runout or weight anywhere.
The useful thing about this listing is that it commits. An R8 spindle, named in the title and again in the specification bullet, is the most widely tooled standard for a machine of this size: collets, end mill holders, drill chucks, boring heads and arbors are available everywhere, and this hub’s introduction is explicit that the tooling standard is the cost you buy into once and pay for indefinitely.
Around it the figures are published where they matter. An 18.9 in X-axis stroke and 13.8 in from spindle to table tell you what will fit and how tall it can be; a 1.5 HP brushless motor with variable speed from 50 to 2,250 rpm covers a 25 mm (0.98 in) drill at the bottom and a small end mill at the top; the spindle tilts ±90 degrees and the head rotates 360, so angled work can be reached from either side. The construction is stated as all-metal with brass gears, with forward and reverse switching and an emergency stop.
Two figures are missing and one of them matters a great deal. There is no runout, which on a mill sets the limit on every hole and slot it will ever produce. And there is no weight, on a machine whose sister on this shelf ships at 118 kg (260.1 lb) — which is a bench question before it is a machining one. The sister machine is the other thing to read carefully: on every published figure it matches this one, and on the spindle standard its own title and its own bullet disagree.

R8 is the spindle taper Bridgeport made standard on American knee mills, and it is the most widely supported tooling standard for machines of this size: collets from 1/8 in upwards, end mill holders, drill chucks, boring heads and arbors are all available off the shelf. This hub’s introduction names the tooling standard as the hidden cost of a machine — you buy into it once and pay for it indefinitely — and R8 is the one with the largest aftermarket. Naming it unambiguously, in the title and in the specification, is the most useful thing this listing does.
On the published data, in two places. Both describe a 7 by 27-1/2 in table, a 50 to 2,250 rpm variable brushless drive, a 13.8 in spindle-to-table distance and a spindle that tilts ±90 degrees and rotates 360. This machine states 1.5 HP and an R8 spindle. The SM028356 states 1300 W and, in its specification bullet, an MT3-ER32 spindle — while its title says R8. R8 and MT3-ER32 are incompatible tooling standards, so that discrepancy is the whole difference between the two purchases.
The bench. No weight is published, and a mill-drill of this class with a 27-1/2 in table is typically 100 to 130 kg (220.5 to 286.6 lb) — the sister machine on this shelf ships at 118 kg (260.1 lb). That is not a folding workbench load. The other unpublished figure is runout, which on a milling machine sets the floor on every hole and every slot it will ever cut.
Same shelf, nearest price — what else that money puts on the bench.

12 V DC · lathe and mill in one · tool-height shims · soft metals only
A 12-volt combination mini lathe and mill that supplies shims to set the tool height — the one adjustment that decides whether a small lathe cuts or rubs.
Best for: Teaching turning and milling on one machine, in wood, plastic and pure copper or aluminum
≈ $235
36 W · 20,000 rpm motor · 3,000 rpm spindle · 0.1 mm (0.004 in)/division
The 36-watt version of the XENDOLL desktop mill, with the same spindle speed, the same handle scale and the same bullets as the 24-watt one.
Best for: The same model and STEM work as the 24 W machine, with half again the motor
≈ $200
7 in swing · 14 in centers · 2,500 rpm variable · reversible · DRO
The only real metal lathe in the American half of this hub — 7 by 14 inches, variable to 2,500 rpm, reversible for left-hand threads, with a digital readout and a cutter kit.
Best for: Turning steel parts on a bench, where the tooling has to come with the machine
≈ $510
