udarowoobrotowy

The term "udarowoobrotowy" is a Polish adjective that translates to "impact-rotary" or "hammer-drill" in English. It describes a type of power tool designed for drilling into hard materials such as concrete, brick, and stone. The key feature of an udarowoobrotowy tool is its dual action: it combines a rotating motion with a percussive hammering action. This hammering action involves rapid, short bursts of force applied along the axis of the drill bit, which helps to break up the material as it drills.

This combined action significantly increases the efficiency and effectiveness of drilling into dense substances compared to a standard drill that only rotates. The impact mechanism can typically be disengaged, allowing the tool to function as a regular drill for softer materials like wood or metal. Udarowoobrotowy drills are commonly used in construction, renovation, and DIY projects where the ability to penetrate hard surfaces is essential. They are available in various forms, including corded and cordless models, and often feature adjustable speed and impact settings for versatility. The term itself is a compound word, with "udar" meaning "impact" or "stroke," and "obrotowy" meaning "rotary" or "rotating."
