Beading Bits 3/8 Radius 1/4 Shank from Bosch are router bits designed for profiling decorative edges where an attractive bead detail is needed, so they give projects a consistent, finished look on visible corners and edges. The bit is classified as a router bit in the profiling category, which means it is built specifically to shape stock rather than drill or bore, helping keep the routing workflow focused on clean edge profiles. The 3/8 inch radius defines the contour of the bead, so every pass produces the same profile size across multiple parts. A 1/4 inch shank matches routers that accept 1/4 inch bits, providing a familiar interface for common woodworking routers. The bit uses two flutes, so it cuts on both sides of the profile for balanced material removal that supports smoother feed and a cleaner edge profile on typical woodworking passes.
This Bosch router bit uses a 1/4 inch shank, so it fits collets designed for 1/4 inch bits and allows the bit to be secured for edge routing operations. The 3/8 inch radius profile is built into the cutting geometry, so once the bit is set at the correct height in the router, each pass creates the same decorative bead along the stock edge. The two flutes share cutting duty around the profile, so the bit removes material progressively as it travels, which supports a controlled feed rate along the edge. A ball bearing pilot at the tip rides on the workpiece edge while the carbide tipped cutters shape the bead, so the bit follows the edge contour while routing and keeps the decorative bead aligned with the original stock line.
This Bosch beading bit is identified as a router bit in the profiling class, so it is suited to tasks where the goal is shaping an edge rather than cutting joinery. The 3/8 inch radius profile is intended for locations where an attractive, decorative edging is needed, such as exposed edges that benefit from a softened, shaped appearance. Because the bit is carbide tipped, the cutting edges at the working end are designed to stay sharp longer than non-carbide tips in typical woodworking use, so the same bead profile can be repeated across multiple parts in a run. The 1/4 inch shank format allows the bit body to be used in routers that accept 1/4 inch shank bits, making it convenient for shop tools already set up for that shank size. The ball bearing pilot at the end of the bit guides the profile along the workpiece edge during routing, so the bead follows edge curves or straight runs that match the pilot path.
The two flute configuration on this Bosch beading bit means the cutters are arranged to remove material on both sides of the bead profile as the bit rotates, which helps balance the cut and supports a smoother finish on the decorative edge. The 3/8 inch radius dimension is fixed into the cutter geometry, so once the router height and fence or guide are set for a pass, every piece run against the ball bearing pilot receives the same bead shape. The carbide tipped construction concentrates carbide at the cutting edges, so the profile remains true over many passes, supporting consistent results across long production runs. The 1/4 inch shank provides a standard interface for 1/4 inch router collets, tying the profile cutter securely to the router so that the bead location relative to the stock face stays stable once set. The ball bearing pilot rolls along the edge while the bit spins, so the bit tracks the workpiece instead of relying on a separate template, helping maintain alignment between the bead and the original edge line.
This Bosch beading bit is a router bit in the profiling class, so it is designed for shaping decorative edges where a bead detail is desired on wood components.
The 3/8 inch radius on this bit creates a bead with a 3/8 inch curved profile, so every routed edge shows the same rounded decorative contour wherever it is used.
The 1/4 inch shank fits routers that accept 1/4 inch bits, so the bit seats in a 1/4 inch collet and allows secure mounting for edge profiling passes.
The Bosch beading bit uses two flutes so cutting is shared around the profile, which supports smoother cutting action and a cleaner decorative edge during routing.
The carbide tipped construction places carbide at the cutting edges, helping the bit maintain a consistent profile shape over many passes in typical woodworking use.
The ball bearing pilot guides the bit along the workpiece edge as it spins, helping the bead follow the edge line so the decorative profile stays aligned with the stock.
The Bosch Beading Bits, 3/8 inch Radius, 1/4 inch Shank are router bits built for profiling attractive edges wherever a bead detail is desired, so they suit projects that call for a consistent decorative profile. With two flutes, carbide tipped cutting edges, and a ball bearing pilot, the bit is configured to shape the 3/8 inch radius contour while tracking along the workpiece edge. The 1/4 inch shank format matches routers designed for 1/4 inch bits, simplifying router selection around that standard interface. For woodworking jobs that specify a 3/8 inch radius bead, this bit provides a defined profile ready to be put to work on visible edges.
