Spadeborrar

Spadeborrar is a term used to describe a specific type of drill bit. It is characterized by its flat, blade-like cutting edge, resembling a spade or a flat shovel. This design allows spade bits to create wide, shallow holes, often used for tasks like drilling pilot holes for screws in woodworking or for creating access points for electrical wiring in thin materials. Unlike twist drills, which are designed to bore deep into material, spade bits excel at clearing material quickly on the surface.

The cutting edge of a spade bit is typically sharpened to a point in the center to help with initial positioning and prevent the bit from wandering. The flat wings then scrape away the material as the bit rotates. They are commonly made from hardened steel to withstand the forces of drilling. Spade bits are often used with hand drills or power drills and are particularly effective in softer materials such as wood, plastic, and some softer metals. They are not designed for drilling deep holes or for precise depth control. The size of a spade bit is usually indicated by its width, referring to the diameter of the hole it creates.
