Preferably, the top end of the first branch flow channel is distributed in an upward inclined manner, and the tail end of the first branch flow channel is communicated with the cooling liquid channel.

Preferably, the second branch flow passage is located below the first branch flow passage, the inclination directions of the second branch flow passage and the first branch flow passage are opposite, and the top end of the second branch flow passage is communicated with the cooling liquid channel.

Compared with the prior art, the beneficial effects of the utility model are that: the end mill for machining the tungsten steel runner is more reasonable in structural design, the chip removal mechanism of the drill bit plate structure at the bottom end is combined with the chip removal mechanism of the cutting edge, so that the cutting efficiency is ensured, and the guide-out structure of the cutting fluid can synchronously and efficiently dissipate heat of the lower section and the upper end of the mill;

1. the arc-shaped structural design of the drill head plate facilitates the chip removal mechanism at the bottom end of the milling cutter to be communicated with the chip removal structure of the cutting edge in a mode that the arc-shaped surfaces of the drill head plate and the cutting edge are communicated, so that the chip removal is more convenient;

2. the use of two subchannel structures is convenient for the cutting fluid can be synchronous follow coolant passage to the bottom and the surface of milling cutter dispel the heat in step.
