Freud 85-031 3/16" Depth Inlay Bit is a precision carbide router bit designed for decorative inlays in solid surface projects. With a 3/16" cutting depth, it creates a ready-to-fill groove that accepts wood, metal, or contrasting solid-surface strips, letting you add striking edge accents to countertops, vanity tops, furniture, and more. Use in hand-held routers for flexible, on-site accuracy and consistently clean results.

What makes this inlay bit special

• Specially formulated carbide optimized for solid surface materials, delivering durable performance and reliable finishes over time.
• 3/16" cutting depth provides a repeatable groove size for precise inlays and predictable results across multiple projects.
• Hand-held router friendly design enables precise control and versatile use on curved edges, corners, and flat surfaces alike.
• Edge-ready profiles produce clean, flush inlay channels that accept wood, metal, or contrasting solid-surface strips with minimal finishing work.

Who should use this bit

• Fabricators and installers working with solid surface materials (e.g., Corian, engineered countertops) who want a sharp, defined inlay groove.
• Woodworkers and furniture makers crafting decorative borders and identity stripes on edge surfaces.
• DIY enthusiasts tackling kitchen islands, bathroom vanities, or custom gift projects that feature contrasting inlays.

Practical uses and project ideas

• Inlaying wood or metal strips into the edge of solid surface countertops to create a luxurious, multi-material look.
• Adding color or material contrast along cabinet faces or vanity tops for a custom, high-end appearance.
• Detailing furniture edges with a contrasting inlay channel to elevate tabletops, shelves, or hutches.

How to use

1. Mark the location and width of the inlay groove on your workpiece.
2. Set the router depth to 3/16" and secure the piece firmly to prevent movement.
3. Feed the bit steadily in a controlled pass, using light passes if needed to minimize chatter and ensure a clean groove.
4. Test-fit your inlay material on scrap to confirm a snug, flush fit; adjust as necessary.
5. Apply appropriate adhesive to the inlay and press it into the groove; clamp until set as required by the adhesive.
6. Flus h sand the surface after curing to achieve a seamless transition between inlay and surrounding material.

Maintenance and tips for best results

• Keep the carbide sharp and free of built-up material to maintain clean cuts and precise grooves.
• Cut at appropriate speeds for solid surfaces and use steady feeds to minimize chipping and ensure a crisp edge.
• Clean and dry the bit after use to extend tool life and prevent corrosion on any exposed surfaces.
• Store with other router bits in a protective case to preserve the cutting edges and maintain accuracy for future projects.
