Husqvarna's mounting arrangement uses a hub with radial indentations and tangential slots to fix abrasive cutting blades flush on cut-and-break tools without permanently attaching the hub to the blade.

Patentradars sammanfattning

This invention by Husqvarna AB describes a separable mounting arrangement for securing abrasive cutting blades flush on construction equipment such as cut-and-break tools, wall saws, and floor saws. A hub with a profiled hub face and a matched flange clamp opposite sides of an axial depression formed around the blade's central aperture, ensuring no hardware protrudes beyond the blade plane. Radial indentations on the hub's central part align with restricted sections of a partly circular central aperture in the blade, allowing bayonet-style axial insertion followed by rotational locking into tangential slots—providing an interlock that retains the blade even if the flange loosens. Because the hub is not permanently attached to the blade, it can be reused across multiple blade replacements without disturbing the drive belt or disassembling the support arm.
