Compare the Whiteside 1474 oval edge bit and 1432 half round bit by profile depth, diameter, and RPM to pick the right edge for your board.
Quick answer
Choose the Whiteside 1474 oval edge bit when you want a subtle 1/8-inch-deep fingernail profile on cutting boards or charcuterie boards. Choose the Whiteside 1432 half round bit when you need a full 180-degree bull nose with a 1/4-inch cut radius for deeper, more prominent edges.
Why the profile depth changes the look and the setup
The 1474 oval edge bit cuts a 180-degree half-moon with a 1/2-inch bead opening and a 1/8-inch bead depth. That shallow depth keeps the profile close to the board face, so it reads as a soft fingernail edge rather than a bold groove. The 1432 half round bit cuts a full 180-degree design with a 1/4-inch cut radius, which removes more material and creates a taller, more visible bull nose. The trade-off is visual weight versus subtlety: the oval edge blends in, while the half round becomes a design feature.
Large diameter and recommended RPM affect stability
The 1432 has a 1-1/8-inch large diameter and a recommended 12,000 RPM. The 1474 has a 3/4-inch large diameter and a recommended 13,000 RPM. A larger diameter bit removes more material per pass, so the 1432 rewards a slower, more deliberate feed and a stable router table setup. The smaller 1474 is easier to control on narrower stock, but you still need to respect the recommended speed. Neither bit is a substitute for a fence or edge guide: the catalog notes that a fence is required on a router table and an edge guide is necessary with a hand router.
Shank and cutting length are the same, so the decision is profile-first
Both bits use a 1/2-inch shank and a 1-inch cutting length, so the choice is not about shank compatibility or cut depth capacity. The 1432 is also available with a 1/4-inch shank if your router only accepts that size, but the 1474 is supplied with a 1/2-inch shank. If your router accepts 1/2-inch shanks, pick based on the edge you want, not on the shank. If it only accepts 1/4-inch, the 1432 gives you a half round option, but you would need to confirm oval edge availability separately.
Trade-offs to weigh before buying
- Profile depth: The 1474 cuts a 1/8-inch-deep fingernail profile; the 1432 cuts a 1/4-inch-radius half round. Deeper profiles need more material removal and can expose more end grain on thin boards. Test the profile on scrap stock of the same thickness before routing the final piece.
- Router table control: Both bits require a fence on a router table. The 1432's 1-1/8-inch large diameter removes more material per pass, so use a slower feed and firm hold-down pressure with that bit. If your router table lacks a fence, fix that before buying either bit.
- Shank flexibility: The 1432 is available with a 1/4-inch shank as well as the 1/2-inch shank; the 1474 is supplied with a 1/2-inch shank. A 1/4-inch shank router can use the 1432 but not the 1474 as supplied. Check your router collet size first; if it is 1/4 inch only, the 1432 is the safer half round choice.
