This specialized tool is designed for heavy-duty drilling and demolition applications in concrete, masonry, and stone. The numerical values likely refer to its dimensions, possibly diameter and length, indicating a substantial size suitable for creating large holes or removing significant material. For instance, it might be used to bore through thick concrete walls or to break up pavement.
Its significance lies in its efficiency and robustness when tackling demanding construction tasks. The specific shank type ensures a secure and powerful connection to rotary hammers, maximizing energy transfer and minimizing slippage. Historically, tools of this type have evolved to meet the increasing demands of construction projects, providing increased power and durability compared to earlier models.
