Product Description
The CMT Roman Ogee Bit with Bearing is a premium router bit engineered to produce the timeless S-curve ogee profile - one of the most elegant and widely used edge treatments in woodworking. With a 1 1/8 in. cutting diameter, a 29/64 in. cutting height, and a 5/32 in. radius, this bit delivers a crisp, classical ogee edge on furniture, cabinet doors, and decorative millwork. Crafted from CMT's industrial-grade carbide, it pairs precision geometry with a bearing guide for repeatable, consistent results on hardwood, softwood, and sheet goods alike.
Key Features
- Roman Ogee Profile - produces the classic double-curve S-shape edge treatment beloved in furniture and cabinet work, giving finished pieces an elegant, professional appearance.
- Bearing Guide Included - the integrated bearing rides along the workpiece edge to control cutting depth consistently, eliminating the need for fences and reducing setup time on handheld routers and router tables.
- 1/2 in. Shank - the larger shank diameter provides greater rigidity in the router collet, reducing vibration and chatter during the cut for a smoother, cleaner ogee profile.
- Hard Metal (HW) Carbide Cutting Material - industrial-grade carbide construction maintains a sharp cutting edge through extended use on solid hardwood, softwood, and composite sheet materials.
- 2-Flute Design - dual cutting edges allow for balanced, efficient material removal and a finer surface finish with each pass.
- Right-Hand Rotation - standard RH rotation is compatible with the vast majority of routers, ensuring straightforward installation with no special tooling required.
- Multiple Passes Recommended - taking the full ogee profile in progressive passes rather than a single aggressive cut reduces stress on the bit and the workpiece, extending tool life and improving edge quality.
Why This Product
- The roman ogee is widely regarded as one of the most popular edge profiles in woodworking - this bit is purpose-built to deliver that exact classic design in a single setup, making it a reliable choice for cabinet doors, furniture rails, and decorative trim.
- The 5/32 in. radius and 29/64 in. cutting height are sized to produce a well-proportioned ogee profile on standard-thickness stock, giving craftsmen the look of hand-carved detail with router precision.
- The included bearing guide keeps the cut depth consistent along curved or straight edges without requiring a separate fence, making this bit equally practical on a router table or with a handheld router.
- The 1/2 in. shank and 2-flute hard metal carbide construction work together to reduce vibration and extend cutting life - a practical advantage when running production quantities of cabinet doors or furniture components.

Frequently Asked Questions
What router machines is this bit compatible with?
This bit features a 1/2 in. shank and right-hand rotation, making it compatible with handheld routers and router tables that accept a 1/2 in. collet - the most common collet size on full-size routers. Confirm your router accepts a 1/2 in. shank before use.
How many passes should I take to cut the full roman ogee profile?
For best results, multiple passes are recommended rather than cutting the full 29/64 in. profile in a single pass. Progressive, lighter passes reduce stress on the bit, improve surface quality, and extend cutting life - especially important when working with dense hardwoods.
What does the bearing on this bit do?
The bearing rides along the edge of the workpiece and acts as a depth stop, controlling how far the carbide cutters engage the wood. This allows the bit to produce a consistent ogee profile without needing a router fence, and it makes curved-edge work straightforward on a handheld router or router table.
What is the radius of the ogee profile this bit produces?
This bit produces a roman ogee profile with a 5/32 in. radius. The full cut has a 1 1/8 in. diameter and a 29/64 in. cutting height, yielding a well-proportioned classical S-curve edge suitable for furniture, cabinet doors, and decorative trim work.
