Use Spade drill bits long for rough boring in wood.
Spade drill bits long are suited for drilling large holes, where other bit types get expensive. They cannot be used to widen existing holes. It is possible to get a nice neat hole with a flat bit but the exit is usually messy.
Drill bits are cutting tools used to remove material to create holes, almost always of circular cross-section. Drill bits come in many sizes and shapes and can create different kinds of holes in many different materials.
Available in a variety of sizes
