Type of milling cutter that is flat with cutting teeth surrounding the tool.

• A. Face mill
• B. End mill
• C. Ball end mill
• D. Slab mill

Answer: (A)

When machining flat surfaces, a cutter that is flat and has cutting teeth arranged around its face is used to remove material efficiently across the surface. This geometry lets the tool shave material from a flat area with multiple inserts, producing a flat, smooth finish in fewer passes. The other cutters have different primary shapes or purposes: one is designed for contouring with edges on the sides and end, another has a rounded tip for shaping curved surfaces, and a wide-perimeter cutter is typically used for heavy roughing on large flats. The flat cutter with teeth around the tool is best described as a face mill because it’s built specifically to create flat, finished surfaces quickly.
