An adjustable disc sander includes: a base defining an operating surface; a sanding device being mounted on the base having a sanding disc; and an adjustable support unit including a linkage unit and an adjustable positioning unit. The sanding disc and the operating surface include a working angle. The linkage unit connects between the sanding device and the adjustable positioning unit. The adjustable positioning unit includes an adjuster being mounted around a support bar along a move direction, and includes a retainer being arranged between the support bar and the adjuster to move between a fixing position and a releasing position in a direction perpendicular to the move direction. When the retainer is at the fixing position, the adjuster can slightly adjust the support bar to achieve fine adjustment of the working angle. When the retainer is at the releasing position, the support bar can move significantly to achieve coarse adjustment of the working angle.

An assembly for guarding a grinding wheel of a bench grinder and a method for manufacturing an assembly for guarding a grinding wheel of a bench grinder are provided. The assembly includes a fixed guard, a sliding guard, and a locking device. The fixed guard is mounted around the grinding wheel and has an opening that provides access to the grinding wheel. The sliding guard is disposed over the fixed guard and designed to slide over the fixed guard to cover or uncover the opening. The locking device is designed to fix a position of the sliding guard relative to the fixed guard. The position of the sliding guard spans from a first position, which corresponds to complete covering of the opening of the fixed guard by the sliding guard, to a second position, which corresponds to complete uncovering of the opening of the fixed guard by the sliding guard.
