INTBUYING SM028356, 7 × 27-1/2 in mill-drill review
The same mill-drill as its stablemate, with 1300 watts instead of 1.5 horsepower — and a spindle standard its own title and its own specification cannot agree on.
Where we come out The same bench mill as its stablemate with a different motor figure, on a page whose title and specification name two incompatible spindle standards.
This hub’s introduction ends on the hidden cost of a machine tool: the tooling standard, which you buy into once and pay for indefinitely. This listing cannot decide what that standard is. The title ends “R8 Metalworking”. The first specification bullet reads “Spindle taper:MT3-ER32”. Those are not variants of one thing — R8 collets and holders go straight into an R8 spindle, while MT3-ER32 wants a Morse taper 3 arbor carrying an ER32 nut — and a tooling set bought for either is useless on the other.
Everything else matches the sister machine on this shelf closely enough to be the same casting: a 700 by 180 mm (7.09 in) table, 350 mm (13.8 in) from spindle to table, infinitely variable speed from 50 to 2,250 rpm, a nose that tilts ±90 degrees and rotates a full 360, forward and reverse switching and an emergency stop. The motor is the one other published difference: 1300 W here, 1.5 HP — about 1,120 W — there, with nothing on either page to explain it.
Two smaller slips are worth noting because they are in the same place. The title gives the speed range as 0-2250 rpm and the bullet as 50-2250; a spindle under power does not turn at zero. And the table is 7 in by 27-1/2 in the title and 7.1 by 27.5 in the specification. The machine ships at 118 kg (260.1 lb), which is the figure to check your bench against before anything else.

What it handles, and what it will not
Strengths
Publishes a table size in the specification — 27.5 by 7.1 in, 700 by 180 mm (7.09 in)
Publishes the spindle-to-table distance, 13.8 in or 350 mm (13.8 in)
A 1300 W brushless motor with infinitely variable speed from 50 to 2,250 rpm
The nose tilts ±90 degrees and, per the listing, actually rotates a full 360
Forward and reverse switching with an emergency stop
Ships at 118 kg (260.1 lb), which is published in the consignment data if not in the bullets
Compromises
Its title says R8 and its specification bullet says MT3-ER32: two incompatible tooling standards on one page
The title gives 0-2250 rpm and the bullet gives 50-2250 — a machine cannot turn at zero under power
1300 W and "1.5HP" on the sister listing are not the same figure, and nothing explains which machine has which motor
No runout figure published
No axis travels published, where the sister machine gives an 18.9 in X stroke

The questions welders ask
Is the spindle R8 or MT3-ER32?
The listing says both, in different places, and they are not compatible. The product title ends with "R8 Metalworking"; the first specification bullet reads "Spindle taper:MT3-ER32". An R8 spindle takes R8 collets and holders directly; an MT3 spindle with an ER32 nut takes a Morse taper 3 arbor and ER32 collets. Nothing bought for one fits the other, and this hub’s introduction names the tooling standard as the commitment that outlasts the machine. Before ordering, this is the question to put to the seller in writing — and the sister machine on this shelf, which says R8 in both places, is the alternative if the answer is unsatisfactory.
Why does the discrepancy matter so much?
Because it is the expensive half of the purchase. A set of R8 collets, an R8 drill chuck arbor, an R8 end mill holder and an R8 boring head is a significant sum, and none of it fits an MT3-ER32 spindle — which wants MT3 arbors and ER32 collets instead. Buying the wrong set is the single most expensive mistake available on this shelf, and it is made by reading the title instead of the bullet, or the other way round.
Is it the same machine as the other INTBUYING mill?
On every other published figure, yes: a 7 by 27-1/2 in table, 50 to 2,250 rpm variable brushless drive, 13.8 in from spindle to table, a nose tilting ±90 degrees and rotating 360, forward and reverse with an emergency stop. The motor is given as 1300 W here and 1.5 HP there — about 1,120 W — which is a real difference that neither page explains. And the references, T028334 and SM028356, share the 028 stem that runs through four brands on this shelf.
