Amana Tool MR0107 22.5 Degree Chamfer Bit with 3/16" Bearing
The Amana Tool MR0107 22.5 Degree Chamfer Bit is a useful router bit for template routing, pattern work, laminate trimming, and curved woodworking parts where control and cutting direction matter. While it is a 22.5 degree chamfer bit, one of the biggest advantages of this bit is the two-bearing design, which gives you more flexibility when routing against changing grain direction.
We use this bit in our shop for flush trimming templates, especially on curved parts where the grain can run both with and against the cut. Being able to work from either direction using the same template setup can help improve cut quality and reduce the need to reposition or remake templates.
What This Router Bit Is Used For
This bit is a strong fit for woodworkers who need more control during template-guided routing and pattern work. It is especially helpful when routing complex shapes, curved parts, or materials where grain direction changes throughout the cut.
- Template routing and pattern work
- Flush trimming templates
- Routing curved woodworking parts
- Working with shapes that run with and against the grain
- Laminate trimming
- Shaped components and custom woodworking parts
- Projects where cutting direction affects tear-out and edge quality
Why We Like This Bit
The two-bearing setup is what makes this bit especially useful for template and pattern routing. It allows the cutter to be used with the template mounted on either side of the workpiece, which means you can change cutting direction without constantly moving the template.
- Great for template routing: A useful bit for flush trimming templates and pattern-guided woodworking.
- Helpful on curved parts: Especially useful when cuts run both with and against the grain.
- Two-bearing design: Lets you route from either direction using the same template setup.
- Reduces template repositioning: Helps save time and makes the routing process more efficient.
- Useful for laminate trimming: A practical option for laminate work, pattern work, and shaped parts.
- Better control on tricky grain: Gives you more flexibility when grain direction changes through the cut.
Recommended Products to Use With This Router Bit
For best results, pair this router bit with the right templates, tape, wood, and supporting accessories for your project:
- Acrylic Woodworking Templates - Use this bit with clear acrylic templates for repeatable routing, pattern work, and flush trimming.

How to Use This 22.5 Degree Chamfer Bit for Template Routing
This bit is especially helpful when a standard routing direction does not give you the cleanest cut on curved or complex shapes. The two-bearing design allows you to use the same template setup from either direction, which can help reduce tear-out when the grain changes.
- Secure your template or pattern to the workpiece.
- Rough cut the shape first with a band saw or jig saw, leaving a small amount of material outside the final profile.
- Install the bit securely in a router that accepts 1/4" shank router bits.
- Use the bearing setup that matches your template position and routing direction.
- Route in the direction that gives you the cleanest cut based on the grain direction.
- If the grain changes through the curve, adjust your cutting direction as needed while keeping the template setup consistent.
- Take controlled passes and avoid forcing the bit through the material.
- Sand and finish the routed edge as needed for your project.
Always follow your router manufacturer's safety instructions. Make sure the bit is properly secured, the template is firmly attached, and the workpiece is stable before routing.

Frequently Asked Questions
What is this router bit used for?
This bit is used for template routing, pattern work, flush trimming templates, laminate trimming, and curved woodworking parts where cutting direction and control matter.
Why is this bit helpful for curved cuts?
When cutting curves, some areas may run with the grain while others run against the grain. The two-bearing design gives you more flexibility to change cutting direction, 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 routing flexibility and helps reduce the need to move the template during the cut.
Can I use this bit for template routing?
Yes. This bit is a good option for template and pattern routing, especially on curved shapes or projects with 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?
No. Even though it is a 22.5 degree chamfer bit, it can also be useful for template-guided trimming and pattern work because of its bearing setup and routing flexibility.
What types of projects is this bit best for?
This bit is well suited for curved templates, pattern routing, laminate trimming, shaped components, and woodworking projects where you need more control over cutting direction.
What is the angle of this chamfer bit?
This bit has a 22.5° angle.
What is the cutting height?
The cutting height is 1-3/8".
What is the shank size?
The shank size is 1/4".
Should I rough cut before using this bit?
Yes. For template routing and shaped parts, rough cut the piece first and leave only a small amount of material for the router bit to remove. This helps improve control and reduces stress on the bit.
The Amana Tool MR0107 22.5 Degree Chamfer Bit is a versatile option for template routing, pattern work, laminate trimming, and curved woodworking parts.
