About Drill Bits
Drill bits are cutting tools which are used to create cylindrical holes. Drill bits are held in a tool called a drill, which spins them and provides the force required to push the drill bit into the material.
Nowadays drill bits are relatively inexpensive and sharpening can be difficult and inconvenient (especially on-site), consequently users often throw away bits that become blunt, and replace them with new bits. This is particularly so for brick and concrete drill bits.
Obviously, there are different drill bit types for cutting into different materials and sometimes different drill bit types for cutting the same materials. But before we get into details, let’s get a bit of terminology under our belt.
