Amana Tool 47168 Flush Trim Compression Bit - Upper and Lower Bearing Guide
The Amana Tool 47168 Flush Trim Compression Bit is a really useful bit for template routing, pattern work, laminate trimming, and flush trimming shaped parts. It is especially helpful when routing curves that move both with and against the grain, where changing cutting direction can help reduce tear-out and improve the finished edge.
We use this router bit in our shop for flush trimming templates, particularly on curved parts where grain direction changes throughout the cut. The upper and lower bearing guide design allows you to use the template from either side of the workpiece, giving you more flexibility to route in the direction that gives you the cleanest result.
What This Router Bit Is Used For
This flush trim compression bit is designed for template-guided routing and pattern work where grain direction, cut quality, and routing flexibility matter. It is a strong option for woodworkers who want more control on complex shapes and curved parts.
- Flush trimming acrylic templates
- Pattern routing shaped woodworking parts
- Routing curved parts with changing grain direction
- Laminate trimming
- Template routing from either side of the workpiece
- Reducing the need to reposition templates during routing
- Improving cut quality on challenging curves and profiles
Why We Like This Bit
The biggest advantage of this bit is the upper and lower bearing guide setup. This allows you to run the template on either side of the workpiece, so you can change routing direction without having to move the template to the opposite face.
- Great for template routing: A strong choice for flush trimming templates and pattern work.
- Helpful on curved parts: Useful when cutting curves that go both with and against the grain.
- Upper and lower bearing guides: Let you route from either direction using the same template setup.
- Reduces template repositioning: Saves time by reducing the need to move your template during the routing process.
- Useful for laminate work: A solid choice for laminate trimming and clean flush trimming applications.
- Good for detailed woodworking: Helps create cleaner results on more complex shaped parts.
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.
- Template Tape - Useful for securing acrylic templates or layout guides to your workpiece before routing.
- Universal Router Base Plate - Helpful for extra router stability and visibility on larger routing projects.
- Dimensional Wood - A great option for template routing, furniture parts, shaped components, and woodworking projects.
- Live Edge Wood - Useful for routed boards and projects where grain direction and natural shape can change throughout the cut.
How to Use This Flush Trim Compression Bit
This bit is especially useful when one routing direction starts to cause tear-out and you want the flexibility to change direction without moving the template to the opposite side of the workpiece.
- 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 either the upper or lower bearing guide depending on your template position and routing setup.
- Route in the direction that gives you the cleanest cut for the grain direction you are working with.
- If the grain direction changes, adjust your routing 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 flush trimming templates, pattern routing, laminate trimming, and shaped woodworking parts. It is especially useful for curved parts where changing cutting direction can help improve the quality of the cut.
Why is this bit good for curved template work?
When routing curves, part of the cut may go with the grain and part may go against the grain. This bit allows you to change routing direction more easily so you can get a cleaner cut and reduce tear-out.
What is the advantage of the upper and lower bearing guides?
The upper and lower bearings let you use the same template from either side of the workpiece. This gives you more flexibility and saves time because you do not need to move the template to keep routing in the best direction.
What does “compression” mean on this bit?
In this case, the compression-style design helps support cleaner trimming performance, especially in applications where cut quality matters and you want more control during template-guided routing.
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.
What types of projects is this bit best for?
This bit is well suited for template routing, laminate trimming, shaped parts, curved woodworking components, and other projects where flush trimming accuracy is important.
Is this a good bit for template routing?
Yes. This is an excellent bit for template and pattern work, especially when working on shapes that require you to route from different directions for the cleanest finish.
What is the diameter of this router bit?
The diameter is 5/8".
What is the cutting height?
The cutting height is 1-3/8".
Should I rough cut before using this bit?
Yes. For best results, rough cut the part first and leave only a small amount of material for the router bit to remove. This helps reduce stress on the bit and usually produces cleaner results.
The Amana Tool 47168 Flush Trim Compression Bit is a strong choice for template routing, pattern work, laminate trimming, and curved woodworking parts where grain direction changes throughout the cut. Use it when you want more routing flexibility, cleaner results, and the ability to work from either side of the template setup.
