Amana Tool 46304 UltraTrim Flush Spiral Up-Cut Bit - 1/2" Diameter
The Amana Tool 46304 UltraTrim Flush Spiral Up-Cut Bit is designed for clean, accurate flush trimming on larger woodworking and template-routing projects. With its 1/2" diameter, 2" cutting height, and 1/2" shank, this bit is a strong choice when smaller trim bits do not give you enough cutting height or stability for the job.
We use this router bit in our shop for flush trimming bigger projects like table leg templates, chair templates, and larger furniture components. The longer cutting height gives you more reach, while the double ball-bearing setup helps the bit track smoothly along a template or workpiece edge.
What This Router Bit Is Used For
This carbide-tipped spiral up-cut bit is made for larger template-guided routing and flush trimming applications where control, reach, and cut quality matter.
- Flush trimming table leg templates
- Flush trimming chair templates
- Pattern routing larger furniture parts

Why We Like This Bit
This bit is especially useful when working on bigger template-based projects where a shorter bit may not have enough reach. The up-cut spiral helps pull chips up and out of the cut, which can improve chip removal and cutting efficiency during larger routing operations.

How to Use This Spiral Up-Cut Flush Trim Bit
This bit is best used when the bulk of the waste has already been removed. For larger furniture parts, rough cut the shape first, then use the router bit to bring the piece cleanly to the template profile.
- 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 1/2" shank router bits.
- Confirm that the double bearings are positioned properly against the template or guide surface.
- Route in controlled passes and avoid forcing the bit through the material.
- Let the up-cut spiral clear chips from the cut while maintaining steady router control.
- Sand and finish the routed edge as needed for your furniture 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.
