Specialty Router Bits

Specialty Router Bits for Custom Millwork, Flooring, and Architectural Details

Some routing tasks demand purpose-built profiles that standard roundovers and chamfers cannot produce. This collection brings together specialty router bits for window sash construction, handrail profiling, tongue-and-groove flooring, wainscot paneling, sign making, and decorative details — all built to Infinity Tools carbide standards for performance in hardwood and softwood alike.

The Window Sash Router Bit Sets machine the full glass-retaining rabbet and cope profile needed for traditional divided-light window sashes. The 1/2-inch Shank Handrail Router Bits produce the curved undercut profile used for code-compliant stair and balcony handrails in one pass at the router table.

Flooring, Paneling, and Decorative Profiles

The Floor Making Router Bit Sets cut matched tongue-and-groove profiles for site-made hardwood flooring, allowing you to mill custom floor stock from wide boards or reclaimed lumber. The Wainscot Paneling Router Bit Set produces the raised field and frame profile used in traditional wainscoting without the need for a shaper.

For sign work, the 8-piece Sign Making Router Bit Set covers the V-groove, roundnose, and profile bits used for lettering and decorative routing. The Flute & Bead Router Bit Set machines classical fluting and reeding profiles for columns, pilasters, and furniture legs.
