The 70mm disc padlock stands out in the realm of security hardware due to its robust design and resistance to common break-in techniques. Its circular, low-profile form is not just a stylistic choice, but a deliberate engineering decision aimed at enhancing security and durability.

At the core of its design is the hardened stainless steel body, shaped into a disc to minimize exposure to cutting and prying tools. Unlike traditional padlocks, the shackle in a disc padlock is mostly hidden within the body, making it significantly more resistant to bolt cutters and saw attacks. Typically, only a small portion of the shackle is visible when locked, further reducing its vulnerability.

The shackle itself is usually made of hardened steel and is 10mm or more in diameter to prevent easy deformation. Its placement also discourages leverage attacks, as the flat shape of the lock offers minimal space for prying tools to grip.

Internally, the lock uses a disc tumbler mechanism or a pin tumbler system with anti-pick features. The disc mechanism is particularly advantageous in outdoor environments due to its resistance to dirt and moisture, which can impede traditional pin tumbler locks.

Moreover, the 70mm size offers a balanced compromise between portability and protection. It’s large enough to secure storage units, gates, and lockers, yet compact enough to be practical for regular use. Most disc padlocks in this size also include a key-retaining feature, ensuring the lock isn’t left unlocked unintentionally.
