摘要

A compact attachment for a power hand drill has a compact frame mounted onto the drill housing by clamps secured by threaded fasteners. Grinding wheels/discs are driven from the drill chuck via geared connection with the grinding angles adjustable. The drill bits are clamped into a holder which is spring loaded to push the bits onto the grinding discs. The system can also be used for dressing the grinding surfaces with access to the grinding wheels for cleaning and replacement.
