Description of the embodiments
The present utility model will be described in further detail with reference to fig. 1.
The embodiment of the utility model discloses a concave arc milling cutter.
Referring to fig. 1, the concave arc milling cutter includes a shank 1 to which a clamp is fixed, one end of the shank 1 is provided with a cutting edge 2 for cutting and a chip pocket 3 for discharging chips, the cutting edge 2 includes an end edge, a peripheral edge, and an arc edge for cutting a workpiece, and the arc edge is for milling a convex R-profile.
