For thicker or hardened steel padlocks, power tools like angle grinders or reciprocating saws are highly recommended.
An angle grinder is a powerful tool designed for grinding and cutting. While it can slice through most metals, stone, and masonry with the correct wheel, it struggles with extremely hard materials like tungsten carbide or thick, case-hardened steels, which will quickly burn out or shatter standard discs.
Hardened steel and titanium are dense, tough metals that standard angle grinders struggle to cut. For these materials, high-powered grinders equipped with specialized cutting discs are necessary. These discs are often made from materials like tungsten carbide or have diamond grit designed for metal cutting.
The ban is due to the high proportion of serious injuries that result from the use of these tools. Common injuries include amputations, serious lacerations and face / eye injuries from shattered cutting and grinding discs.”
