ütvecsavarozó

The term "ütvecsavarozó" is a Hungarian word that translates to "impact driver" in English. It refers to a type of power tool designed specifically for driving screws and bolts with significantly more torque than a standard drill or screwdriver. This is achieved through a mechanism that delivers rotational force in short, powerful bursts, often accompanied by an audible hammering sound.

Impact drivers are characterized by their compact size and high torque output, making them ideal for demanding tasks such as fastening large lag bolts, driving screws into dense materials, or working with stubborn fasteners. The impact mechanism engages when the tool encounters resistance, allowing the user to apply significant force without stripping the screw head or over-torquing the fastener. This makes them a valuable tool for construction, automotive repair, and general DIY projects where high torque is required.

While similar in appearance to a cordless drill, an impact driver typically has a different chuck system, often a 1/4-inch hex collet, designed to accept hex-shank bits. They are usually powered by rechargeable batteries, offering portability and convenience. The controlled impact action helps to prevent the user's wrist from twisting, a common issue with high-torque applications using traditional tools.
