ABUS 60/50

Difficulty Notes

The Abus 75 line is described as a 'tough little open'. The 75/30 and 75/40 are noted as 'unnecessarily hard' by some users. The 75/50 and 75/60 are considered good for practicing dimple pins. Some users found the learning curve for dimple picking frustrating even with locks on lower belt ranks.

Picking Notes

The Abus 75/50 and 75/60 require manual counter-rotation of the core to set pins because they have a dead core. The 75/30 and 75/40 have a sprung core which allows tensioning easier. For the 75/50 and 60, picking in the same direction as tension is possible but far from optimal; counter-rotation is needed. Users suggest starting with spools and counter-rotation in regular pin tumbler locks before attempting these dimple locks.

Sources (r/lockpicking):
- u/Zer0pi314 (3pts): 'The 75/50 has the dead core... The 75/60 has the spring tension core'
- u/GeorgiaJim (2pts): 'They have a sprung core which makes tensioning easier than the 75/50 and 60 which are dead core. The hard part with the Abus padlocks is finding a flag that fits the keyway well.'
- u/GeorgiaJim (1pts): 'If you're already comfortable with spools and counter rotation in regular pin tumbler locks start there as the feedback and learning curve won't be so high that you need to start at entry level dimple locks.'

Tension Tips

For the 75/50 and 75/60 (dead core), you must manually counter-rotate the core to set pins. Picking in the same direction as tension is possible but suboptimal. For the 75/30 and 75/40 (sprung core), tensioning is easier. Finding a tension wrench flag small enough to fit the keyway well is a critical step.

Bitting Variance

The Abus nomenclature uses two numbers (e.g., 55/40) where the second number indicates the shackle width in millimeters. The 75/30 and 75/40 have smaller key sizes and identical cores (4 pins if memory serves). The 75/50 and 75/60 have full-size keys. The 75IB series is mentioned as a variant that is not under spring tension. Some listings for Abus locks specify minimum sizes; larger sizes in the same series (e.g., 55/50, 55/60) often share the same keyway as the smaller listed size (e.g., 55/40).
