What are Drill Bits?
Drill bits are cutting tools that are made to fit into a rotating drill. A drill, fitted with a drill bit, is used to cut cylindrical holes of many different sizes in many different materials. The terms drill and drill bit can be confusing as sometimes they are used to describe both the cutter holder (drill) and cutter (drill bit) itself. Drill bits are available in a wide range of sizes and types. A steel drill bit is usually less expensive than a carbide-tipped drill bit. The best idea when buying drill bits is to find the kind that offers the quality and features most needed for the job.
