YONICO 13161q 1/8-Inch Radius Round Over Edge Forming Router Bit
The 1/8″ radius round over edge bit by Yonico features a 1/4″ shank and a 1/8″ cutting depth. It is designed to add a gentle rounding to edges on a variety of surfaces and projects. The blade uses premium C3 micro-grain tungsten carbide for a sharper and longer-lasting edge, making it suitable for drawers, table edges, and decorative trims.
NICAVKIT 6Pcs Roundover Router Bit Set
This 6-piece set covers radii from 1/8″ to 1/2″ with a 1/4″ shank. The bits are built from YG6 tungsten carbide blades mounted on a hardened 1045 steel body. An anti-kickback design helps maintain control, and the set is suitable for hardwood, softwood, and plywood. It’s a practical choice for decorative edges, sign-making, or cabinetry where multiple edge profiles are needed.
YONICO 13170 1-1/4-Inch Radius Round Over
This router bit provides a generous 1-1/4″ radius with a 1-1/4″ cutting depth and a 1/2″ shank. It’s well-suited for large moldings or furniture edges that require a pronounced rounded profile. Yonico uses premium carbide blades for durability, offering a stable cut on solid wood and plywood with consistent results.
YONICO 13171 1-1/2-Inch Radius Round Over Edge
With a 1-1/2″ radius and a 1/2″ shank, this Yonico bit is designed for substantial roundings. It’s ideal for edge profiles on tabletops, door frames, and large cabinetry components. The C3 micro-grain carbide blades ensure a sharp, long-lasting edge for consistent finishes on hardwoods and softwoods alike.
YONICO 13162q 1/4-Inch Radius Round Over Edge
This 1/4″ radius round over bit uses a 1/4″ shank and cutting depth suited for mid-sized edge rounding. It’s a balanced option for furniture components, cabinet doors, and decorative trims. The premium carbide blades provide a clean cut with reduced tear-out on a range of wood types.
Buying Guide: Key Considerations For Roundover Router Bits
- Radius selection: Small radii (1/8″ to 1/4″) offer subtle rounding suitable for edges that must remain slim and tight, such as cabinet doors. Larger radii (3/4″ to 1-1/2″) create pronounced curves ideal for table edges, decorative moldings, or signwork. Choose based on the visual weight you want and the thickness of the workpiece.
- Shank size: A 1/4″ shank fits most compact routers, while a 1/2″ shank provides greater rigidity and reduces vibration on larger cuts. If you have a handheld router with lower horsepower, stick with a 1/4″ shank for better control.
- Blade quality: Carbide blades, especially premium micro-grain carbide, stay sharp longer and resist dulling on dense hardwoods. Higher-quality blades reduce burn and produce cleaner edges over extended use.
- Material compatibility: Most roundover bits are designed for wood, plywood, MDF, and some composites. Avoid metals and non-wood materials that can dull blades quickly or cause kickback.
- Bearing guides and safety: Some sets include bearings or anti-kickback designs to improve control. Ensure you follow router safety practices and maintain steady feed rates to minimize tear-out.
- Application scope: For cabinet doors or fine furniture, smaller radii combined with multiple passes can achieve refined edges. For architectural trims or large tabletops, larger radii may be more efficient and aesthetically appropriate.
- Maintenance: Regularly clean the bits, remove resin buildup, and store them dry to extend blade life. Inspect shanks for wear and ensure proper seating in the router collet before use.
In sum, these rounded-edge router bits provide a range of radii and shank options to match your project scale and router capabilities. When selecting, consider the edge profile you want, the material you’ll cut, and the power of your router to ensure clean, consistent results.
