Corner Rounding Router Bits with Ball Bearing Guide
* 4 flute design for super-smooth finish.
**Use replacement bearing 47712 and 47718 for corner rounding or 47701 and 47706 for beading.
Note: Bits with 1" and above diameter are not guaranteed due extreme diameters. For best results using a large diameter bit, it is best to first use a smaller radius bit or chamfer the material prior to using the larger radius bits. Tool life will be prolonged and a smoother finish will result.
#MR0110, MR0112 , MRR112 & MR0114 are Corner Round Bits with Miniature Ball Bearing Guides.

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.
