Corner Rounding Cutter — 3/8″ Radius, Pro-Line (1-1/4″ Bore)

Rounds a 3/8″ radius on furniture components, millwork and architectural trim — a substantial round for stair parts, heavy table edges and components meant to be gripped. Runs counterclockwise with the wood fed face down; an opposite-rotation version (FB-CR-PL-006-R) runs counterclockwise with the face up where the setup demands it. The Pro-Line body carries a 1-1/4″ bore at 4″ diameter on three wings, in carbide or T-Alloy — carbide for general production, T-Alloy where abrasive stock or long runs between sharpenings justify the premium. The Mini-Pro equivalent is MC-65-006 on a 3/4″ bore at 2-15/16″. Freeborn indexes this series by radius and the trailing SKU number is that radius in sixteenths, so 006 is 3/8″, 008 is 1/2″ and 012 is 3/4″. For the same radius with a longer reach see the extended corner round P-33-006; to cut a cove and a rounding together see P-34-006.
