Description
Technical field
This utility model relates to cutter of drill machine technical field, particularly relates to a kind of Multifunctional drill.
Background technology
On workpiece, the hole of machining high-precision typically requires and first uses drill bit machined bottom, by boring cutter or reamer the end of to
Hole carries out polish, finally with rose reamer, the bottom outlet of polish is being carried out chamfering, and processor is more, and working (machining) efficiency is relatively
Low, and due to the cumulative error of various operations, the machining accuracy in the hole being finally completed also tends to the highest.
Chinese patent CN201442122U discloses the two-step diamond drill bit that a kind of machining uses, including a handle
With second order bit body, it is characterised in that second order bit body makes two steps, is welded with Buddha's warrior attendant at the cutting on first step
First blade of stone, is welded with the second blade of diamond at the cutting on second step.Two blades of the program and brill
Head body is all connected as a single entity, and after one of them breaks down, overall just damage of drill bit cannot be continuing with, and waste is relatively big, increases
Production cost.
