The Oxford Grinder S1 is the ultimate high-security lock with a 14mm shackle, engineered to resist angle-grinder attacks. Its anti-disc cutter coating is designed to withstand an average of 10 angle-grinder discs before one side of the shackle can be cut through.

Both the Grinder S1 and S2 are designed to outlast and outperform leading locks, resisting up to 5x more cutting discs thanks to their hardened square steel shackles and advanced anti-angle grinder carbide coating. The unique faceted carbide surface deflects grinder blades from edge to edge, rapidly destroying discs and dramatically slowing down theft attempts.

A high-security double-locking system prevents shackle rotation, meaning thieves must cut through both sides of the lock to gain access.
