Square holes in steel · review
Stepless speed from 440 rpm — no belt to move, and a bottom end low enough for a 20 mm (0.79 in) bit.
Where we come out The convenience that makes correct speeds actually happen.
A belt-change press has every speed available in theory. In practice people drill at whichever speed the belt was left on, because opening the head costs a minute. A dial removes the excuse — and the result is bits that last and holes that are round.
Quill travel, the figure that decides how deep a hole you can drill in one plunge. The cheaper Scheppach on this page publishes 50 mm (1.97 in); this one publishes none.
Every figure above comes from the manufacturer’s published specification for this reference. Fields the listing does not publish are left out rather than estimated. Market availability was verified per market on the EAN.

It depends on how often you change speed. With a belt, changing means opening the head and moving it by hand — so most people leave it where it is and drill everything at the wrong speed. A dial removes that friction, and using the right speed is what makes bits last. If you drill one material with one bit size, it is money wasted.
Run large bits in steel. Below about 500 rpm you can drive a 16 to 20 mm (0.63 to 0.79 in) bit without cooking its edge, provided the machine has the torque to hold the speed. That is the top end of what a bench press is asked to do, and machines whose lowest speed is 600 or more cannot get there.

Mixed-material work where the speed changes several times an hour
Here because the consumable states this machine by name.
Specifications: the manufacturer sheet for welding and metalworking machines and the matching Amazon product page. Prices and availability: Keepa. Every figure on this page names its source.
710 W · 13 mm (0.51 in) in steel · 90 mm (3.54 in) quill travel · €250
Ninety millimeters of quill travel — nearly twice the entry machines, and the figure that decides deep holes.
Best for: Deep holes in solid stock, and anyone tired of repositioning halfway down
1/4 HP induction · 5 speeds 620–3,100 rpm · 10 in swing · laser alignment
A ten-inch bench press with a 620 rpm bottom gear and a laser alignment system — the slowest speed of the two stepped machines on this shelf.
Best for: A bench where the hole has to land where the line says, in steel up to about 10 mm (0.39 in)
≈ $200
1,400 W · 800 rpm fixed · 40 mm (1.57 in) boring · 2,810 lbf magnet · 11 cutters
A magnetic drill with a 40 mm (1.57 in) cutter capacity and one fixed speed of 800 rpm — which is the opposite of what this hub’s buying tip asks for.
Best for: Holes in structural steel plate of 10 mm (0.39 in) or more, where the machine has to go to the work
≈ $175
