Amana Tool MRR112 1/4" Round Over Bit with 3/16" Bearing
The Amana Tool MRR112 1/4" Round Over Bit is a great bit to keep in the shop when you want to soften edges and give your woodworking projects a smoother, more finished look. A 1/4" round over is a classic all-around profile that adds comfort in the hand while still keeping a clean, refined appearance.
We use this router bit for adding a round over to charcuterie boards and tables. It is a simple detail, but it makes a big difference in how the finished piece looks and feels. Softening a sharp edge helps make projects feel more professional, more comfortable to handle, and more complete overall.
What This Router Bit Is Used For
This round over bit is designed for creating a smooth rounded edge on wood projects. It is a practical option for makers, furniture builders, cutting board makers, sign makers, and woodworkers who want a more comfortable finished edge without creating an oversized profile.
- Charcuterie boards and serving boards
- Tables and furniture parts
- Shelves and small woodworking projects
- Wood signs and plaques
- Small boxes and decorative projects
- Cutting boards and butcher block projects
- General woodworking projects that need a classic rounded edge
- Projects where you want to remove a hard square edge cleanly
Why We Like This Bit
A 1/4" round over is a useful middle-ground size. It is more noticeable than a tiny edge easing, but still subtle enough to work well on a wide range of projects. For many boards, tables, shelves, and furniture parts, it gives the edge a finished feel without taking over the design.

How to Use This 1/4" Round Over Bit
This bit is typically used after your project has been cut, shaped, and prepared for edge detailing. A 1/4" round over is a good choice when you want a noticeable but still clean rounded edge.
- Make sure your project edge is clean, stable, and ready for routing.
- Install the round over bit securely in a router that accepts 1/4" shank router bits.
- Set the bit height based on the round over profile you want to create.
- Use the bearing to guide the bit along the edge of the workpiece.
- Take a controlled pass and avoid forcing the bit through the wood.
- For harder woods or delicate pieces, use lighter pressure and a steady feed rate.
- Sand the routed edge lightly and finish the project based on its intended use.
Always follow your router manufacturer's safety instructions. Make sure the bit is properly secured, the workpiece is stable, and your hands are safely positioned before routing.

Important Use Note
Please note: there is no warranty on this bit.
To help reduce the chance of damage, avoid applying too much force while routing. Excess pressure can put strain on the bearing and lock ring. For best results, use lighter pressure and a steady, controlled feed during the cut.
This bit performs best when used with a lighter, more controlled approach rather than forcing the cut.

What should I avoid when using this router bit?
Avoid forcing the cut or putting too much pressure on the bit. Keeping the cut controlled helps reduce stress on the bearing assembly and can help extend the life of the bit.

Yes. Test the bit on scrap material first so you can confirm the round over size, router setup, and final edge profile before using it on your finished piece.
