7 common types of edge forming router bits

Edge forming router bits are essential tools used in woodworking to shape and create decorative profiles along the edges of various materials, such as wood, plastic, or composite materials. These bits are designed to be used with a router, a power tool that spins the bit at high speeds, allowing for precise and controlled cuts. Edge forming router bits are available in a wide variety of profiles and sizes, each capable of producing unique edge shapes and designs. Let's explore some of the most common types in more detail:

1. Roundover Bits: Roundover bits are widely used for creating a rounded profile on the edge of a workpiece. These bits typically have a radius or diameter measurement that determines the size of the roundover. Common sizes range from 1/8-inch to 1-inch or more. Roundovers are versatile and popular because they add a smooth, curved finish to edges, eliminating sharp corners and providing a pleasant tactile feel.

2. Beading Bits: Beading bits are used to create a decorative bead along the edge of a workpiece. The bead can be small or large, depending on the specific bit used. Beading adds an elegant and traditional touch to furniture, cabinetry, and other woodworking projects. Some beading bits may include a bearing that guides the bit along the edge, making it easier to create consistent beads.

3. Cove Bits: Cove bits produce a concave profile along the edge of a workpiece. They create a smooth, curved recess that can be used for decorative purposes or as a functional detail. Cove profiles are commonly used in trim work, moldings, and architectural details. These bits are available in various sizes, allowing for different depths and widths of coves.

4. Roman Ogee Bits: Roman ogee bits create an "S"-shaped profile with a concave and convex curve along the edge of a workpiece. This profile adds an elegant and decorative look to the edge. The Roman ogee profile is often seen in furniture, picture frames, and other woodworking projects where a classic and sophisticated appearance is desired.

5. Chamfer Bits: Chamfer bits are used to create a beveled edge on the workpiece. They remove material at a specific angle, resulting in a clean and angled edge. Chamfers can be used to break or soften sharp edges, add visual interest, and create a professional and finished look. Common chamfer angles include 45 degrees and 22.5 degrees, but different angles can be achieved by adjusting the bit height or using specialized bits.

6. Bullnose Bits: Bullnose bits create a half-circle profile on the edge of a workpiece. These bits produce a smooth, rounded edge that is comfortable to touch. Bullnose profiles are often used for creating decorative edges on furniture, stair treads, and countertops. Router bits with bearings can be used to guide the bit along the workpiece, ensuring accurate and consistent results.

7. Ogee Bits: Ogee bits create a double curve profile with an "S"-shaped edge. This profile is commonly used for decorative purposes and adds a sophisticated look to the workpiece. Ogee profiles can vary in complexity, with some bits featuring multiple curves and levels. These bits are often used in furniture making, cabinetry, and architectural millwork.

When working with edge forming router bits, it's important to consider the size, depth, and speed of the cut. It's recommended to start with lighter passes and gradually increase the depth to achieve the desired profile. Additionally, using a router table with a fence or a guide can help maintain consistent results and improve safety.
