Definition: 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.

Explaining
the Specifications:
- (d) -> The diameter of the shank or shaft. This size should be the same as the collet size of your router. Example: a small router is mostly supplied with a quarter inch collet that is 6,35 mm inside diameter.
- Common collet sizes:
- 1/4" collet = 6,35mm inside diameter
- 8mm collet = 8mm inside diameter
- 12mm collet = 12mm inside diameter
- 1/2" collet = 12,7mm inside diameter
- NOTE that the 12mm and
the 12,7mm (1/2") sizing are often misunderstood. 1/4 inch is not 6mm but
e
xactly
6,35mm. A 6mm shank will not fit in a 1/4 in collet. Wrong sizes will either
break the collet or the bit will fall out.
- TCT = Tungsten Carbide Tipped
- Allways stay in the MAX Speed range of router bit
