Amana Tool Corner Rounding Carbide-Tipped 2-Flute w/Ball Bearing Guide

Edge of Arlington offers free shipping in the United States when you choose flat rate shipping

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 part of a complex one. Also known as a 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.

Includes Miniature sizes:

The smallest guide bearings in the industry! If you’ve often wanted to trim and shape small details in tight corners, but were disappointed by the scoring and burning left behind by solid pilot bits, we have what you are looking for—8 of the most commonly used profiles in miniature sizes, complete with miniature ball bearing guides. These bits are perfect for signs, lettering, small boxes, and musical instruments—essentially any project that requires tiny flush trimming or shaping. Don’t let the small size fool you, these bits are precisely machined and carbide-tipped.
