Kivipuurid

Kivipuurid, often translated as stone drills or rock drills, are tools specifically designed for boring holes into hard materials like stone, rock, and concrete. Historically, these tools were crucial for construction, mining, and quarrying operations. Early forms of kivipuurid were manual, relying on human power to rotate a bit or hammer it against the surface. These often involved heavy mallets and chisels or augers.

The development of mechanized kivipuurid marked a significant advancement. Pneumatic drills, powered by compressed air, became widely adopted due to their efficiency and power. These drills use rapidly vibrating or rotating bits to break down the rock. Hydraulic systems also power some kivipuurid, offering immense force for demanding tasks. Modern kivipuurid can range from handheld jackhammers to large, truck-mounted drilling rigs.

The operation of a kivipuur typically involves a hardened cutting bit that is either rotated or impacted against the material. For rotary drills, the bit spins while applying downward pressure. Percussion drills, on the other hand, deliver rapid hammer blows to the bit, fragmenting the rock. Dust extraction systems are often integrated to manage the debris generated during drilling, which is important for both worker safety and the longevity of the tool. Kivipuurid are indispensable in various industries, facilitating everything from building foundations to extracting geological resources.
