Drilling tools are specialized instruments used to create holes in various materials, such as wood, metal, and concrete. Common types include drills, drill bits, and augers. These tools can be powered manually or by electricity, making them versatile for both professional and DIY projects. Different drilling tools serve specific purposes. For instance, twist drill bits are ideal for general-purpose drilling, while spade bits are used for larger holes in wood. Hammer drills combine rotary motion with a hammering action, making them effective for drilling into hard surfaces like concrete.
