Only if you use regular metal discs. Using diamond discs, you break through in less than a minute in those locks: [1]

Comparing with your CyclyngWeekly link:

- the Litelock X3 goes from 5min to cut only 50% of the shackle to 23s fully cut.

- the Abus Granit Super Extreme 2500 also could only be cut to 50% in 5min, while the diamond disc finished in 29s.

- the Hiplok D1000 couldn't be fully cut in 5min with 2 metal discs, it took 52s with a diamond one.
