I can't say anything about the Albrecht, but I purchased a Rohm 1/2", key style chuck for my, then new, drill press a couple of years ago. It is marked as made in Germany.
I recently did some runout checks on that chuck and the unmarked, unbranded 20mm key style chuck that came with the drill press. Both are mounted with MT adapters. The unbranded one seems to actually be better.
With the drill chucks I took two measurements, one while rotating the spindle at the pulley and the other with the spindle still, but applying moderate, sideways pressure to the drill rod.
Runout measurements:
Spindle, above the chuck: < +/- 0.001" (measured twice at 90 degree positions)
Using a length of 1/2" drill rod:
Near the chuck:
Rohm 1/2": Rotating: +/-0.002" / Pressure: +/-0.002"
No Name 20mm: Rotating: +/-0.010" / Pressure: +/-0.004"
About 5" below the chuck:
Rohm 1/2": Rotating: +/-0.002" / Pressure: +/-0.002"
No Name 20mm: Rotating: +/-0.006" / Pressure: +/-0.0025"
Each of these measurements were taken with the drill rod in two positions in the chucks, about 120 degrees apart. And yes, the numbers did change. I am reporting the largest of the two readings above.
As you can see, the no-name chuck is actually better than the Rohm. The difference seems to be at the position 5" below the chuck jaws and this would be indicative of the angle of the jaw faces that grip the drill. Of course, the cutting edges of the drills will be a distance below the chuck, not just below it.
I purchased the Rohm chuck because the no-name, 20mm one would not hold small drills, like 1/8" and I use it most of the time. I only mount the 20mm one for drills larger than 1/2". Both of them are just fine for 99.9% of any holes I may ever want to drill.
I do not have any keyless chucks, not yet anyway.
