Solid Carbide Spiral Flush Trim & Compression Flush Trim Router Bits
Flush trimming is one of the most common routing operations — trimming laminate to a substrate, cleaning up glue joints, or tracing a template to produce duplicate parts. Solid carbide spiral flush trim bits cut cleaner and last longer than standard carbide-tipped bits, and the compression geometry variants eliminate tearout on veneered and laminated workpieces where both faces must remain intact.
The 1/2-inch shank Solid Carbide Spiral Flush Trim Bits provide maximum rigidity for trimming hardwood edge banding and template routing in thick stock. The 1/4-inch shank versions are suited for trim routers and lighter applications.
Compression Flush Trim for Veneer Plywood and Laminate
When trimming veneer-core plywood or high-pressure laminate, a standard upcut flush trim bit can chip the top veneer on exit. The Solid Carbide Compression Flush Trim Bits combine upcut and downcut flutes to shear both surfaces cleanly in a single pass. The Compression Double Bearing Pattern Bits add a second bearing for flexible template orientation — useful when routing cabinet carcasses or curved parts where the template can be above or below the workpiece.
The 2-piece Compression Double Bearing Pattern Set covers the most common size range. For flush trim technique and router table setup guides, visit the Infinity Tools Learning Center.
