Which cutter is used to make concave surface on a work piece?
-
Angle cutter
-
Convex cutter
-
Corner rounding cutter
-
Radices cutter
D
Correct answer
Explanation
A radiused cutter (also called a radius cutter) is specifically designed to create concave surfaces or internal radii on workpieces. Angle cutters create V-shaped grooves, convex cutters make convex surfaces, and corner rounding cutters create rounded external corners. The term 'radices' in the option appears to be a misspelling of 'radius' or 'radiused'.
