The basic concept of shovel teeth:

Seven Shovel Teeth Cutter Geometry Features

Shovel Teeth Cutter Geometry describes a relieved-tooth form in which the surface behind the cutting edge is shaped to provide clearance. This construction is common on form cutters because it can help preserve the required cutting profile as the tool is resharpened on the rake face, supporting repeatable dimensions and longer usable tool life.

Important features include the tooth profile, relief curve, rake angle, clearance, tooth pitch, gash depth, cutting width, cutter diameter, and mounting bore or shank. The design must balance edge strength, chip space, cutting force, profile accuracy, and sharpening allowance. It is often used for concave, convex, gear-related, thread, and other special-form milling applications.

Select the profile from the finished part drawing and confirm material, tolerance, machine rigidity, and sharpening method. Control runout, alignment, speed, feed, coolant, and chip evacuation, and inspect teeth for uneven wear. A specialist form cutter supplier can support tool selection. General milling cutter information also explains cutter forms, teeth, materials, mounting, and applications.
