Roundover bit vs ogee bit: the profile decision

A roundover bit shapes the square corner of a board into a quarter-round. The Yonico listings describe it plainly: add a round over edge to a variety of surface edges and projects, or create small moldings to be used on its own or as part of a molding build-up. It is the quiet profile, it softens edges without drawing attention. An ogee bit cuts the classic S-curve, a concave sweep flowing into a convex one, and it reads as decoration from across the room.

Match the profile to the project, not the other way around. If the piece will be handled, knocked or wiped down often, the roundover’s smooth curve resists chips and feels good in the hand. If the edge is a visible design feature on a table apron, a picture frame or a cabinet door, the ogee earns its extra setup. You can also combine them: a roundover on the working edges and an ogee on the show edge.

What the roundover listings tell you

Radius is the first decision. The four listings here span 1/8 inch to 3/4 inch radii: the Yonico 13161q cuts a 1/8 inch radius, the Totowood set covers 1/8, 3/16, 1/4 and 5/16 inch, the MEIGGTOOL set runs from 1/8 up to 1/2 inch, and the Yonico 13168 cuts a full 3/4 inch radius. A small radius just breaks the corner; a large radius reshapes the whole edge.

Shank size comes next. Three of the four use a 1/4 inch shank, which fits compact routers and most CNC spindles with a 1/4 inch collet. The Yonico 13168 uses a 1/2 inch shank, and the MEIGGTOOL set includes a 1/2 inch to 1/4 inch collet so its bits fit either. Read our 1/4 vs 1/2 shank router bits comparison if you are choosing a router to go with the bits.

All four list carbide cutters: C3 micro-grain tungsten carbide on both Yonicos and the MEIGGTOOL set, C2 carbide inserts on the Totowood set. The Totowood and MEIGGTOOL listings name guide bearings, which ride the edge and set the cutting depth. Stated materials overlap on solid wood, hardwood, softwood, MDF, particle board, plywood and acrylic. The MEIGGTOOL listing warns to avoid cutting metal and non-wood materials.

Roundover gear: four picks, ranked

The four bits below are ranked by their HQ Score, best first. Every figure is from the listing.

1. MEIGGTOOL 7-piece roundover set

Seven roundover bits on 1/4 inch shanks with radii of 1/2, 3/8, 5/16, 1/4, 7/32, 3/16 and 1/8 inch, industrial grade C3 micro-grain carbide cutters, solid hardened steel bodies and guide bearings. The set includes a 1/2 inch to 1/4 inch router collet, and the listing states a 1 year warranty. It is the only pick here with a warranty term, and the widest radius spread in one box. Note that the spec table lists 7 flutes for a 7-piece set, which reads like a mislabeled field; the title and bullets describe seven bits.

2. Yonico 13168, 3/4 inch radius

A single 3/4 inch radius roundover bit on a 1/2 inch shank with a 3/4 inch cutting depth, premium C3 micro-grain tungsten carbide blades and silver induction brazing, for table mount and handheld routers. It is the largest profile here by far. The spec table lists a 0.5 inch cutting diameter, which does not match a 3/4 inch radius bit; trust the title and bullets for the radius and shank.

3. Totowood 4-piece roundover set

Four roundover bits on 1/4 inch shanks with radii of 1/8, 1/4, 3/16 and 5/16 inch, C2 carbide inserts and a bearing guide, for CNC and other automatic routers as well as handheld and table-mounted routers. Stated materials include solid wood, hardwood, softwood, MDF, particle board, plywood and acrylic. The spec table lists only 1 item and a 0.25 inch cutting diameter, both of which clash with the 4-piece title and the stated radii; trust the title and bullets.

4. Yonico 13161q, 1/8 inch radius

A single 1/8 inch radius roundover bit on a 1/4 inch shank with a 1/8 inch cutting depth, C3 micro-grain tungsten carbide blades and silver induction brazing, for table mount and handheld routers. The spec table lists a 0.38 inch cutting length, a 0.75 inch cutting diameter, a 1.12 ounce weight and 2 flutes. It is the simplest pick here: one bit, one small radius, no set to store.

Set up the cut

Roundover bits are bearing-guided, so the bearing rides the workpiece edge and sets the profile. The Totowood and MEIGGTOOL listings name the bearing outright; the Yonico listings describe table mount and handheld use. Take the cut in sensible passes on hardwoods rather than forcing the full profile at once, and keep the bearing clean so it spins freely.

Match the bit to the material with our best CNC router bits for hardwood guide, or start from a full CNC bit set for woodworking if this is your first set of profile bits.

FAQ: lasers and CNC

What is the difference between a roundover bit and an ogee bit?

A roundover bit cuts a plain rounded edge, a quarter-round that softens the corner. An ogee bit cuts a decorative S-curve edge. The listings featured here are all roundover bits.

Which roundover radius should I start with?

The sets here start at 1/8 inch and run up to 1/2 inch, with the single Yonico 13168 reaching 3/4 inch. A 1/8 or 1/4 inch radius suits edges that get handled; save the 1/2 and 3/4 inch radii for wide, visible edges.

Do I need a 1/2 inch shank?

Not for these small profiles. Three of the four picks use a 1/4 inch shank, and the MEIGGTOOL set includes a 1/2 inch to 1/4 inch collet. The 3/4 inch Yonico 13168 is the only one that needs a 1/2 inch collet.

Can these bits cut acrylic?

The Totowood and MEIGGTOOL listings name acrylic among the materials. Note that the MEIGGTOOL listing also warns to avoid cutting metal and non-wood materials, which sits oddly against its own acrylic mention; follow the stated material list and keep metal out of the cut.

What does the guide bearing do?

The bearing rides along the workpiece edge and controls how deep the profile cuts. The Totowood and MEIGGTOOL listings both name a bearing guide on their bits.
