A pineapple pattern drilling and milling cutter used for machining a carbon fiber composite board comprises a blade part, the blade part comprises an end blade and a chip containing groove which are formed in the end of a cutter body and a chip discharging groove and a circumferential blade which are formed in the circumferential side of the cutter body, the end blade is a drill tip cutting blade, and the chip discharging groove comprises a left spiral chip discharging groove and a right spiral chip discharging groove. And the circumferential cutting edge comprises a left spiral cutting edge and a right spiral cutting edge which are formed based on the chip grooves. According to the drilling and milling cutter, the machining actions of plunge milling and side milling of the carbon fiber composite board can be achieved at a time, the circumferential blades arranged in the pineapple pattern shape can cut off bidirectional carbon fiber structures distributed in a net shape in time, the defects of tearing, burrs,
