When you're building furniture, cabinets, or any wood project, the edge you choose can make or break the look. A sharp square edge might feel modern, while a soft roundover gives a comfortable touch. But with so many options—square, roundover, chamfer, bevel, ogee, and more—how do you pick the right one? This guide covers the most common woodworking edge profiles, how to create them, and what to avoid. Whether you're a beginner or a seasoned DIYer, you'll find actionable advice to get professional results.
1. Square Edge: Clean and Modern
A square edge is exactly what it sounds like—a 90-degree angle with no rounding. It's the simplest edge, often left as-is after cutting. Use it for modern or minimalist designs, like contemporary tables or shelving. However, square edges are prone to chipping and can feel sharp. To avoid splinters, sand the edge lightly with 220-grit sandpaper. For a flawless look, use a sharp blade and cut with the grain. Avoid on high-traffic surfaces like countertops where edges get bumped.
2. Roundover: Soft and Safe
The roundover is the most popular edge profile. It creates a smooth, rounded curve, making it comfortable to touch and resistant to chipping. Router bits come in various radii: 1/8", 1/4", 3/8", and 1/2". For a subtle touch, use a 1/8" or 1/4" roundover on table edges. For a softer feel, go with 3/8" or 1/2". Pro tip: Run the router at a moderate speed (around 15,000 RPM) and feed the wood against the rotation. Avoid climbing cuts to prevent tear-out. Always test on scrap first.
3. Chamfer and Bevel: Angled Elegance
A chamfer is a flat angled cut, usually at 45 degrees, while a bevel can be any angle. Chamfers add a decorative detail without being too fancy. Use a chamfer bit with a pilot bearing, or set your table saw blade to 45 degrees. Bevels are great for box joints or picture frames. Common mistake: cutting too deep, which weakens the edge. Keep the chamfer width to about 1/8" to 1/4" of the thickness. For a clean cut, use a sharp blade and make multiple passes if needed.
4. Ogee and Cove: Decorative Profiles
Ogee edges have an S-shaped curve, often found on traditional furniture like dressers or crown molding. Cove edges are concave, creating a groove. These profiles require a router table for consistency. Beginner tip: Start with a simple ogee bit (e.g., Roman ogee) and practice on pine. To avoid burning, reduce router speed and use a light pass. Cleanup is key: sand the profile with a foam sanding block or use a detail sander. Avoid these on thin stock (less than 3/4") as they can weaken the wood.
5. Router Bit Selection and Safety
Choosing the right router bit matters. For most edges, use a carbide-tipped bit with a bearing guide. The bearing follows the wood edge, ensuring consistent depth. Key parameters: shank size (1/4" vs 1/2"), bit diameter, and profile shape. For safety, always wear eye and ear protection. Secure your workpiece with clamps or a featherboard. Never force the router; let the bit do the work. If you get burn marks, slow down feed rate or check bit sharpness. A dull bit causes tear-out.
FAQ
What's the best edge for a dining table? A 1/4" or 3/8" roundover is ideal—comfortable and durable.
Can I make edges without a router? Yes, use sandpaper, a block plane, or a file for simple roundovers or chamfers. For consistent profiles, a router is best.
How do I avoid tear-out on plywood? Score the cut line with a utility knife, then use a router with a sharp bit. Alternatively, apply painter's tape along the edge.
What's the difference between a chamfer and a bevel? Chamfer is typically 45°, while bevel can be any angle. Both are angled cuts, but chamfer is more precise.
Should I sand before or after routing? Sand the flat surfaces before routing to avoid dust in the profile. After routing, lightly sand the edge with fine grit.
Final Tips for Perfect Edges
Practice on scrap wood before your final project. Keep your router bits clean and sharp. When in doubt, go with a roundover—it's forgiving and looks great. And remember: the best edge is the one that fits your design and feels right. Now grab your router and start creating!
