Abstract
The utility model relates to the field of cutting, in particular to a drill bit. Hole expansion drill bits sold in markets have various specifications, corresponding hole expansion drill bits need to be replaced when holes in different diameters are drilled in the hole expansion work every time, a cutter head of the drill bit is also easy to abrade, and inconvenience is brought for work. By aiming at the problems, the utility model provides a hole expansion drill bit capable of changing the diameter of the drill bit according to the diameter of drilled holes. The hole expansion drill bit provided by the utility model consists of a drill body 1, a drill handle 2, a positioning drill bit 3, a drill sleeve 4, a compression sleeve 5, a cutter handle 6, a fixing block 7, a cutter head 19 and the like. The hole expansion drill bit has the advantages that the structure is simple, and the diameter of the drill bit can be regulated according to the diameter of the drilled holes, so the cutting work of different hole diameters in a certain range can be completed by one hole expansion drill bit, the cutter head can be ground or replaced after becoming dull through being used, the service life is prolonged, and the production cost is reduced.
