The ABUS 55mm Rock Steel Padlock is built with one goal: resist attack. The hardened shackle and body construction make it extremely resistant to bolt cutters, saws, and pry attacks. The key cylinder is pick-resistant and bump-resistant — this lock takes security seriously.

ProsExcellent price/performance ratioShackle guardLock pick protectionDrill resistantCorrosion resistanceCan be keyed alike9/10 ABUS safety ratingGood protection against bolt cuttersConsNot the strongest ABUS makes (strongest lock costs over double)When it comes to bolt cutter proof padlocks, the ABUS 83CS/55 is one of the best on the market when weighing price versus performance. ABUS is one of the best known companies for providing quality padlocks that are super strong, and this lock is no exception. When it comes to security, ABUS has a ranking system that goes up to 10.
While many of our ABUS locks on this list have a 10 rating, you pay a pretty penny for that rating. This is roughly half the cost of the most secure ABUS locks and has a 9/10 safety rating. Not too shabby considering you don’t have to break the bank to get it.
The best feature on this lock is the shackle guard, protecting the shackle on both sides. This makes it difficult mechanically to get the bolt cutters near the shackle. It’s also made of hardened steel, making it further resistant to being cut by bolt cutters.

Pros360 Degree Protection: Circular design allows for protective measures to be double sided. It also combats the traditional means of bumping a padlock open.Affordable priceKeyed alikePull/drill resistantStainless steelCorrosion resistantConsNot heavy duty like some more expensive modelsWhen determining vulnerability of a padlock, one of the first places to examine is the shackle size and accessibility. The smaller or more compact the shackle is, the more difficult it will be to cut; bolt cutters cannot properly fit through thus not being able to supply enough force to penetrate the lock.
This is where the ABUS Diskus comes into play. 360 degree protection make it an affordable padlock that can’t be cut. This ABUS Diskus is available in two different sizes, 50mm and 80mm. When the padlock is in place, due to the shackle being surrounded, it is almost impossible to actually access it. The ABUS 26/70 Diskus comes keyed alike.
German made assures a quality product will be in your possession. Their stainless steel and production standards really take it to the next level. While it can be applied by itself, ABUS recommends pairing this padlock with a hasp to further protect from attack or tampering.

Buying Guide
What to look for before you buy
Cutter Jaw Size
Match the jaw opening to the material you need to cut. 18-inch cutters handle up to 5/16-inch soft metal. 24-inch handles 3/8-inch. 36-42 inch cutters take on 1/2-inch hardened bolts. Bigger jaws mean more leverage and cutting power.
Handle Material & Grip
Fiberglass handles are lighter and don't conduct electricity. Steel handles are stronger but heavier. Rubber grips reduce hand fatigue on long cutting sessions. For electrical work, always choose insulated fiberglass handles.
Our Verdict
The ABUS 55mm Rock Steel Padlock is virtually indestructible. The ABUS Granit 37ST/55 is the best stainless option.
