MR0112 Amana Tool 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 project without creating a large profile. A 1/8" round over is subtle, clean, and perfect 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’s a small detail, but it helps make a project feel more finished and more comfortable in the hand. This size is especially nice when you want a softer edge without making the profile too bold.

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, 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’s a great choice for smaller projects or cleaner, more minimal designs.

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 — this is one of the ways we use it in our own shop. A 1/8" round over helps give charcuterie boards a cleaner, softer edge without making the profile too large.

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 passes 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.
