Edge Beading Bits, 1 Flute, 1/8" Radius, 7/8" Diameter, 1/4" Shank, 2-1/8" Length

Bosch Edge Beading Router Bit For Clean Profiles

Bosch edge beading router bit gives a 1/8 inch radius profile that creates a consistent decorative edge on new work and helps match many older molding profiles. The 7/8 inch cutting diameter produces a substantial bead that reads clearly on cabinet parts and furniture components. A 1/4 inch shank fits common routers that accept this shank size, so it drops into many shop setups without changing the overall system. Overall length of 2-1/8 inches provides enough reach for typical edging passes while keeping the bit compact for better control at the router table or with a handheld router. The bit is carbide tipped, so the cutting edges are designed to hold up during repeated profiling of hardwoods and man-made materials. A ball bearing pilot guides along the workpiece edge, helping the bit track the contour while the cutter forms the bead.

Key Edge Beading Details That Support Your Work

• The 1/8 inch radius cutting profile shapes a small, defined bead that softens sharp edges without removing excessive material, which is useful when you want a finished look while keeping part dimensions close to plan.
• The 7/8 inch diameter cutting circle lays out a wide enough path for a visible molding detail, helping face frames, shelves, and trim parts stand out with a single pass instead of multiple lighter cuts.
• The 1/4 inch shank interface fits routers designed for that collet size, allowing this bit to be used in many compact or mid-size routers that are common in cabinet and trim shops.
• The overall 2-1/8 inch length balances reach and stability, so the bit extends far enough for edge work while keeping the cutting geometry closer to the bearings and collet for smoother operation.
• The carbide tipped construction puts wear-resistant cutting edges at the perimeter of the bit, supporting longer service life across multiple jobs before sharpening is needed.
• The ball bearing pilot at the tip follows the workpiece edge, so the cutter stays aligned to the stock and maintains a consistent bead profile even when the material edge varies slightly.

Installation And Setup For Accurate Edge Profiles

The 1/4 inch shank on this Bosch edge beading router bit slides into a matching 1/4 inch router collet, so mounting centers the bit securely for accurate rotation. With an overall length of 2-1/8 inches, the bit seats deeply while still projecting enough to set cutting height for the 1/8 inch radius bead. The 7/8 inch diameter and ball bearing pilot work together during setup: the bearing rides the stock edge while height adjustments determine how much of the radius engages the material, letting you tune the bead size relative to the workpiece face. Because the bit is carbide tipped, installers and shop users can run standard profiling passes knowing the cutting edges are designed for repeated contact with typical woodworking materials.

Using This Router Bit In Molding And Profiling Work

Where This Edge Beading Bit Fits Your Projects

This router bit is identified as a Bosch edge beading router bit in the profiling class, so it is oriented toward shaping decorative edges on cabinet parts, furniture components, and similar pieces. The 1/8 inch radius bead works well when a subtle profile is needed that still breaks the edge and adds visual interest, such as on shelves, rails, or door parts. With a 7/8 inch diameter, the bit establishes a bead that shows clearly on face frames and trim without overwhelming narrow stock, which suits many cabinet and casework applications. The web description notes that this versatile bit adds attractive edging on new pieces and matches many older molding profiles, so it can be used both for fresh work and for tying in to existing trim runs where an older bead style needs to be echoed.

Details That Support Repeatable Beads And Less Rework

The ball bearing pilot on this router bit runs along the workpiece edge as the carbide tipped cutters shape the 1/8 inch radius bead, helping the profile stay consistent from piece to piece. Because the bearing directly follows the material edge, the 7/8 inch diameter cutting circle keeps the bead aligned, which is important when running multiple cabinet doors or rails that must match in appearance. The 1/4 inch shank and 2-1/8 inch overall length contribute to stable mounting, so the bit remains centered during operation and helps reduce chatter that can lead to sanding or rework. As a carbide tipped, edge beading profile in the router bits class, it is set up for repeated passes on production or semi-production jobs where a dependable, repeatable edge detail saves time during finishing and installation.
