[0001] This utility model relates to the field of drill bit equipment technology, and in particular to a novel group drill. Background Technology
[0002] In multi-hole drilling operations, existing drilling machines generally use a single drill bit to perform drilling operations in multiple passes. Especially in scenarios with dense holes (such as honeycomb panels and multi-hole molds), a single drill bit needs to be repeatedly positioned, drilled, and moved to complete multi-hole processing. Frequent pulling and moving operations consume time.
[0003] Therefore, in order to solve the above problems, a new type of swarm drill is proposed. Summary of the Invention
