Cove Router Bits

You’re restoring a Victorian-era mantelpiece, but your chisel skills leave the coves looking like a toddler’s scribble. Sanding can’t fix this. Enter cove router bits—the unsung heroes behind the graceful, concave curves that define everything from Shaker cabinetry to Greek Revival crown molding. Whether you’re crafting furniture, millwork, or DIY decor, here’s how to master the tool that turns “basic” into “Baroque” without hand-carving blisters.

Cove Router Bits 101: The Curve That Built America

Coves aren’t just decorative—they’re structural and stylistic marvels:

• Shadow Drama: Concave curves catch light, making flat surfaces look hand-carved.
• Glue & Spline Beds: Perfect for reinforcing joints in tabletops and panels.
• Historic Accuracy: Replicate 18th-century moldings or mid-century modern flair.
• Material Versatility: Carve wood, MDF, acrylic, and even soft aluminum.

Real-World Win: A Charleston restorer used a ¾” cove bit to clone $10,000worthofantebellumceilingmedallions—charging$250/hour for “period-authentic craftsmanship.”
