Half-Round Convex Cutter — 1/4″ Radius, 1/2″ Width, Mini-Pro (3/4″ Bore)

Cuts a 1/4″ radius flute — a half-round hollow — into the face or edge of a workpiece, for reeded columns, fluted pilasters, decorative panel work and finger-pull details. The mating half is the half-round concave cutter (MC-64-004), which forms the corresponding bullnose; run the pair to make a rounded tongue that seats in a matching hollow. Radius and width move together as the geometry requires: this cutter’s 1/4″ radius spans a 1/2″ width. Runs counterclockwise. The Mini-Pro body carries a 3/4″ bore at 2-15/16″ diameter on three wings, in carbide. The Pro-Line equivalent is FB-HR-PL-004 on a 1-1/4″ bore at 4″.
