Käsiporakoneissa

Käsiporakoneissa, commonly known as hand drills or brace and bits, are manual tools used for drilling holes in wood and other materials. Unlike modern electric drills, they rely entirely on human power. The tool typically consists of a crank mechanism attached to a chuck that holds a drill bit. The user rotates the crank, which in turn spins the drill bit, allowing it to bore into the material.

These tools were once ubiquitous in carpentry and woodworking before the advent of electric power. They are still valued by some craftspeople for their quiet operation, precision, and the tactile feedback they provide. The slow speed of rotation offered by a hand drill can be advantageous for starting holes accurately and preventing tear-out, especially in delicate work. Different types of drill bits can be used, including auger bits, which are designed for efficient wood drilling.

Operating a käsiporakone involves holding the body of the tool with one hand while turning the crank with the other. Downward pressure is applied to advance the bit into the material. The ergonomic design of older models often featured wooden handles for grip and comfort. While less common today, they remain a testament to the ingenuity of traditional toolmaking and are still found in many antique tool collections and used by those who appreciate traditional woodworking techniques.
