Does a drill press or a hammer drill have more torque

I've recently bought this hammer drill for the purpose of getting a drill press holder. I like my tools modular.


I was about to get above type of drill press, when I checked my options for an actual drill press

I was expecting much significantly better specs:
both nearly the same top speed — 3000 rpm for my drill and 2900 rpm for the latter. both has 12 speeds, but mine has a handling of 7A, while the latter is 3.85A.

To me, at least torque is more important than speed and neither shows it explicitly.

So,

  1. Which one has a higher torque?

    If I was to assume that the current handling is actually reached at some given (usable) speed and assuming that given (usable) speed is nearly the same for both drills, then my current drill has more peak torque, obviously. Assuming the given speed is usable.

  2. If my drill has higher torque, then why so? I mean look at the casing for the latter's drill, it's definitely larger.

If torque is your objective, the drill press is going to provide more. It appears to use the same gearing as my quite-old Sears Craftsman drill press in that one releases a sliding motor mount, pulling the motor forward. Re-position the drive belts to a different pair of stepped pulleys for ratio change, then re-tension by pushing the motor aft and tightening the clamps/levers/bolts.

Any time you reduce speed by a gearing change, torque is increased. The hammer drill likely uses some form of electronic speed change, pulse width modulation, for example. As such, the amount of power transmitted is reduced for a specific period of time. Reduced (electrical) power, reduced torque.

One can bog down a variable speed hand drill by running it at a low enough rpm. It is nearly impossible to do so with a belt drive drill press, if one had one geared low enough to match.

I see that your hammer drill is not 12 speeds, but fully variable across the speed range, by the way.

Each tool choice is a compromise of sorts. The drill press will provide a stable surface on which to place parts and provide for greater accuracy with respect to squareness and precision. It's not going to be something to drag out to the backyard or driveway for an assembly project, however.

The hand drill has portability and light weight, but lacks precision and stability. A hole saw bit in a drill press is a good combination for comparison. Put the same hole saw into a hand drill and you won't get quite as smooth a hole and if the saw is large enough, it will be challenging to hang on to.

On the flip side, you won't be using a drill press to prepare concrete for anchors, as you can with the hammer drill.

Why not buy both?
