Amana Tool MRR112 Miniature 1/4 Radius Corner Rounding with 3/16 Dia Ball Bearing x 11/16 Dia x 13/32 Cut Height x 1/4 Inch Shank Carbide Tipped Router Bit

2 Flute & 4 Flute
The router bits found on this page include the miniature 3/16" and 1/4" diameter ball bearings for routing tight spaces, the In-Tech™ insert replacement knife series, diamond tipped (PCD) bits as well as the standard 1/2" diameter ball bearings.

The basic edge-forming bit, the corner-rounding bit rounds an edge to a given radius. The tool is shouldered to cut a fillet. The cut can be used to ease edges, as a simple profile, or as a part of a complex one. Also known as roundover, rounding over, and quarter-round. If a smaller pilot bearing is used, a second shoulder can be produced, in effect making the bit a beading bit.

Tool #DRB-504 is excellent for composite panels, fiberglass, fiberglass PCB board, fiberglass reinforced composites, lightweight composites, custom composite materials, fiber-reinforced urethane and fiber-reinforced structural foam floors.
