Amana Tool MR0112 1/8" Round Over Bit with 3/16" Bearing
The Amana Tool MR0112 1/8" Round Over Bit is a great choice when you want to slightly ease the edge of a woodworking project without creating a large profile. A 1/8" round over is subtle, clean, and ideal for projects where you want to remove the sharpness of a square edge while keeping the overall look crisp and refined.
We use this router bit for adding a round over to charcuterie boards and tables. It is a small edge detail, but it helps make a project feel more finished, more comfortable in the hand, and more professional without making the edge profile feel too bold.

How to Use This 1/8" Round Over Bit
This bit is typically used after your project has been cut, shaped, and prepared for edge detailing. Because a 1/8" round over is a subtle profile, it is a good choice for finishing edges without changing the look of the piece too dramatically.
- 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, reduce RPM speed by 30% to 50% and use a steady, controlled approach during the cut.
This bit performs best when used with lighter pressure and controlled routing.

Frequently Asked Questions
What is a 1/8" round over bit used for?
A 1/8" round over bit is used to slightly soften and round over the sharp edge of a board or project. It creates a subtle profile that improves comfort while keeping the piece looking clean and crisp.
What projects is this bit best for?
This bit is great for charcuterie boards, tables, signs, boxes, shelves, cutting boards, serving boards, and general woodworking projects where you want a small, understated round over.
Why use a 1/8" round over instead of a larger round over bit?
A 1/8" round over is ideal when you want just a slight easing of the edge rather than a bold rounded look. It is a great choice for smaller projects, clean designs, and pieces where you want the edge softened without changing the overall shape too much.
Can I use this bit in a standard router?
Yes. This bit has a 1/4" shank, so it fits routers that accept 1/4" shank router bits.
Is this a good bit for charcuterie boards?
Yes. A 1/8" round over helps give charcuterie boards a cleaner, softer edge without making the profile too large.
Can I use this bit on tables?
Yes. This bit can be used to add a subtle round over to table edges and furniture parts when you want a softer, more comfortable edge without a large radius.
Why is there no warranty on this bit?
This bit can be damaged by too much force or excess pressure on the bearing and lock ring, so it is sold without warranty. Lighter pressure, reduced RPM, and controlled routing are recommended.
What should I avoid when using this router bit?
Avoid forcing the bit through the cut or putting too much pressure on it. Slowing the RPM and using a more controlled feed can help reduce stress on the bit.
Should I test the profile before using it on my finished project?
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.
Should I sand after routing the round over?
Yes. A light sanding after routing helps remove any sharpness or tool marks before applying your finish.
