Example 1

A tool bit with a suction channel, as shown in fig. 1 to 5, comprising: the cutter rest 21, the cutter bar 3 and a plurality of blades 22; the tool rest 21 comprises a cutting surface and a connecting surface, and each blade 22 is fixedly connected with the cutting surface of the tool rest 21; a discharge port 204 is arranged on the connecting surface, and a first feed port 202 is arranged on the cutting surface; the side surface of the knife rest 21 is provided with a plurality of second feed inlets 203; the knife rest 21 is also internally provided with a suction channel 201; the first feed port 202 and the second feed port 203 communicate with the discharge port 204 through the suction passage 201.

In one embodiment, the blade 22 is a ceramic blade. In another embodiment, the blade 22 is a metal blade. The user can select different blades according to different materials to be cut and replace the blades.

The cutter arbor 3 is built-in to have first material chamber 31 that inhales, and the one end of first material chamber 31 that inhales is connected with discharge gate 204, and the other end is connected with actuating mechanism's tool bit connecting axle 115, and the tool bit connecting axle 115 embeds has the second to inhale the material chamber 119, and discharge gate 204, first material chamber 31 and second inhale the material chamber 119 and communicate in proper order.

Specifically, one end of the cutter bar 3 is connected with the discharge hole 204 in a clamping way, and the other end of the cutter bar is provided with a quick connector, so that the quick connector is connected with the cutter head connecting shaft 115 quickly, and the replacement of parts is facilitated.
