Product Details

Drills are many times used in woodworking, metalworking, machine tool fabrication, development and utility projects. Specially designed versions are made for medicine, Space, and miniature applications.


There are many types of drills. Some are powered manually, others use electricity (electric drill) or compressed air (pneumatic drill) as the intent power, and a minority are pushed via an inside combustion engine (for example, earth drilling augers). Drills with a percussive motion (hammer drills) are often used in challenging substances such as masonry (brick, concrete and stone) or rock. Drilling rigs are used to bore holes in the earth to gain water or oil. Oil wells, water wells, or holes for geothermal heating are created with large drilling rigs. Some kinds of hand-held drills are also used to force screws and different fasteners. Some small appliances that have no motor of their personality may additionally be drill-powered, such as small pumps, grinders, etc.
