MR0107 Amana Tool 22.5 Degree Chamfer Bit with 3/16" Bearing

The Amana Tool MR0107 22.5 Degree Chamfer Bit is a really useful bit for template and pattern work, especially when working on curves that run both with and against the grain. Its design gives you more flexibility during routing, helping you make cleaner cuts without constantly needing to reposition your template.

We use this bit in our shop for flush trimming templates, particularly when cutting curved parts where changing cutting direction can make a big difference in cut quality. Because of the two-bearing design, you can work from either direction using the same template, which makes the process more efficient and helps reduce tear-out on tricky grain.

This bit is a solid option for woodworkers doing template routing, pattern work, laminate trimming, and curved part shaping where control and versatility matter.

What We Use It For

We use this router bit for flush trimming templates, especially when:

• Cutting curved parts

• Routing areas that run with and against the grain

• Doing pattern work where changing cutting direction helps produce a cleaner finish

This is a really helpful bit when a standard approach doesn’t give you the cleanest cut on curved or more complex shapes.

Product Features

This bit is designed for laminate work, template routing, and pattern work. The two-bearing setup allows the cutter to be used with the template mounted on either side of the workpiece. That means you can cut from either direction using a single template, without having to stop and move the template to the opposite side.

That added flexibility can be a big advantage when routing curved parts, especially when grain direction changes throughout the cut.

Frequently Asked Questions

What is this router bit used for?
This bit is used for flush trimming templates, pattern work, and laminate trimming. It is especially useful when routing curved parts where grain direction changes throughout the cut.

Why is this bit helpful for curved cuts?
When cutting curves, some areas of the cut may go with the grain while others go against the grain. This bit’s design allows you to change cutting direction more easily, which can help improve cut quality and reduce tear-out.

What is the advantage of the two-bearing design?
The two-bearing design allows you to use the same template from either side of the workpiece. This gives you more flexibility and helps you cut from either direction without needing to move the template.

Can I use this bit for template routing?
Yes — this bit is a great option for template and pattern routing, especially on shapes with curves or changing grain direction.

Can this bit be used 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 bit only for chamfering?
Even though it is a 22.5 degree chamfer bit, the way this bit is being used here is for template-guided trimming and pattern work, where its bearing setup and cutting profile offer more routing flexibility.

What types of projects is this bit best for?
This bit is well suited for curved templates, pattern routing, laminated parts, shaped components, and woodworking projects where you need more control over cutting direction.
