Figure 2 yes Figure 1 A three-dimensional schematic diagram comprises a tool handle 1 and a tool head 2, wherein the tool head 2 has a front end face 210, and the front end face 210 is a plane. The outer periphery of the tool head 2 is provided with a plurality of blade grooves 22 along the length direction and a plurality of blade backs 25 along the circumferential direction. The rear ends of the blade grooves 22 extend to the blade backs 25, and chip grooves 26 are provided between adjacent blade grooves 22. The chip grooves 26 extend from between two adjacent blade backs 25 toward the tool handle 1.

[0033] The utility model is provided with a flat front end surface to improve the strength of the blade body, and a blade back is provided to improve the support and strength. The peripheral blade groove is provided between the blade back to ensure the stability of the blade groove and the strength of the blade.

[0034] The cutting edge 22 includes a first flank 221, a second flank 222, and a third flank 223, all of which extend to the blade back 25. The arrangement of the first flank 221, the second flank 222, and the third flank 223 reduces wavy vibration marks, resulting in a smoother machined surface. The blade back 25 provides support and ensures the strength of the blade, preventing breakage when machining titanium alloys and fiberglass, resulting in improved strength.

[0035] The clearance angle of the first formed flank surface 221 is 12°, the clearance angle of the second formed flank surface 222 is 25°, and the clearance angle of the third formed flank surface 223 is 35°.

[0036] The front end side surface of the cutting groove 22 is provided with a first formed relief angle 27 and a second formed relief angle 28. The first formed relief surface 221 is connected to the first formed relief angle 27, and the second formed relief surface 222 and the third formed relief surface 223 are connected to the second formed relief angle 28. The provision of the first formed relief angle 27 and the second formed relief angle 28 in the present invention enhances the strength of the entire blade and prevents vibration marks from being generated.

[0037] The peripheral rake angle 24 of the cutting edge groove 22 is 35°. The large rake angle design of the present invention enables sharper cutting.

[0038] The depth of the cutting groove 22 is 3.2 mm, which makes the cutting sharper and reduces the occurrence of chatter marks. The contours of the first flank 221, the second flank 222, and the third flank 223 of this embodiment are spline curves. Compared with the previous tools using tangent circles, the cutting effect is better and sharper, thereby reducing the occurrence of chatter marks.

[0039] The core diameter of the cutter head 2 is 6 mm. The core diameter of the cutter head of the present invention is smaller and the weight is lighter.

[0040] The helix angle of the chip flute 26 is 35°.
