What Size Round Over Bit for 3/4 Wood? [Our Recommendations]

Creating a profile around the edge of a workpiece is a regular activity in the woodworking shop. A radius, or round over, is by far the most popular profile.

Round over bits is used for anything from merely shaping the corners of a workpiece for the better aesthetic and tactile appeal to producing round overs as part of the overall design. Round over bits may also be used to make bullnose and thumbnail profiles.

How Do I Determine Round Over Bit Size

The radius of the curve you want determines the size of the round-over bit you use; these two are 3/4″ (above) and 1/16″ (below). Round over bits are sized by radius and are ideal for smoothing harshly squared edges.

The sizes range from a 1/16″ radius that hardly breaks a square edge — in fact, unless you have a lot of edges to round over, you would be better off using a sanding block — to a 1-1⁄2″ radius bit that is probably considerably greater than most woodworker would require.

(There is even bigger round over cutters, but they’re more for industrial use.) You Kehonrakennus virtuaalitodellisuuden kuntosalilla zudena 100 mennessa suomessa udenafil la vera scuola del bodybuilding naturale ora esiste can purchase a kit with a variety of bits, but if you’re anything like me, you’ll use the 1/4″, 3/8″, and 1/2″ radius bits the most.

Round over bits are often used to make a smooth, uniform curve on a workpiece, but they also feature one sharp cutting edge at the bottom of the radius that, when completely extended, forms a 90-degree cut at the top of the round over.

A round-over bit creates a beautiful thumbnail edge when used in this way. A beading bit is a variant of the round-over bit that features 90-degree cutting edges on both the top and bottom. The bit generates a curve with a 90-degree corner on either end.

What Router Bit Size Do I Need For 3/4-Inch Wood?

In short, for 3/4″ thick material, a 1/2″ Radius bit is the standard. You’d use a 3/8″ bit to round half the thickness and a 1/2″ bit to round three-quarters of the thickness if you want one flush edge.

The round over radius is used to calculate the round over bits, as I have told you before. A 3/4″ round-over bit would, thus, round the whole edge of 3/4″ thick material into a quarter circle shape.
