Frequently Asked Questions

What is a top-bearing flush-trim bit?

A top-bearing flush-trim bit has its guide bearing positioned above the cutter rather than below. The bearing rides along a template or reference edge placed on top of the workpiece, trimming the material beneath flush to the template profile.

When should I use a top-bearing bit instead of a bottom-bearing bit?

Use a top-bearing bit when the template is fastened to the top face of the workpiece or when the reference surface is above the router table—such as trimming edge banding flush to a panel using the panel itself as a guide from above.

What is the advantage of solid carbide over carbide-tipped flush-trim bits?

Solid carbide bits are ground from a single carbide blank, providing more consistent edge geometry, better vibration resistance, and longer edge life in abrasive materials like MDF, plywood, and laminate. They are also resharpenable to original geometry more precisely than brazed-tip bits.

What is a compression flush-trim bit?

A compression flush-trim bit has upcut flutes at the bottom of the cutter and downcut flutes at the top. When the full cutter height is engaged, fibers on both faces of the panel are sheared toward the center, eliminating tear-out on both the face and the back of the workpiece.

What is a double-bearing pattern bit?

A double-bearing pattern bit carries a bearing both above and below the cutting flutes. This allows the same bit to follow a template placed either above or below the workpiece without changing the bit setup.

What materials can solid carbide spiral flush-trim bits cut?

These bits cut solid hardwoods, softwoods, MDF, plywood, melamine, high-pressure laminate, and composite materials such as Corian. The spiral geometry and solid carbide construction handle abrasive materials better than standard carbide-tipped bits.

Can these bits be used in a CNC router?

Yes. Solid carbide spiral flush-trim bits are well suited for CNC use due to their balanced geometry and superior wear resistance. For a broader range of CNC-optimized tooling, browse the CNC collection.

What shank sizes are available for top-bearing flush-trim bits?

Both 1/4" and 1/2" shank versions are available. Use 1/2" shank bits in full-size routers for reduced vibration and cleaner cuts; 1/4" shank bits are appropriate for compact and trim routers.

What is the difference between these bits and the flush-trim bits in the main flush-trim collection?

This collection focuses specifically on solid carbide spiral bits with a top-bearing configuration, including compression and double-bearing variants. The broader flush-trim collection includes bottom-bearing and carbide-tipped options alongside these solid carbide spiral versions.

Are these bits covered by a quality guarantee?

Yes. All Infinity Tools solid carbide spiral bits are backed by our quality guarantee. Contact us if a bit does not perform as described.
