    Description

    Bosch Roundover Router Bit For Smooth Edges

    Bosch roundover router bit is a profiling router bit that produces smooth, uniformly rounded edges, so cabinet and woodworking edges look consistent from piece to piece. The bit is classified as a router bit for rounding over, which focuses it on edge-shaping work rather than material removal. A 5/32 inch radius profile creates a modest round that breaks sharp corners without removing too much material, which helps keep stock dimensions predictable during production runs. The cutter has a 13/16 inch overall diameter that sets the path width as it travels along the workpiece, guiding how close you work to adjacent features or joinery. A 1/4 inch shank diameter fits routers that accept 1/4 inch shank tooling, which keeps this bit in line with many trim and mid-size routers used in cabinet shops. Overall length of 1-7/8 inches keeps the bit compact for better control at the work surface.

    Key Bosch Roundover Details For Woodworkers

    • The 5/32 inch radius on this Bosch roundover router bit shapes a gentle curve along edges, which helps ease corners on doors, shelves, and trim without dramatically changing the profile.
    • The 13/16 inch bit diameter defines the cutting circle, which helps plan how close you can work to adjacent profiles while still achieving a clean rounding cut.
    • The 1-7/8 inch overall bit length keeps the cutting geometry close to the collet, which supports controlled passes along cabinet parts and smaller workpieces.
    • The 1/4 inch shank diameter matches routers and trimmers that accept 1/4 inch bits, which lets you use this profile with compact tools often used for finish work.
    • The design is described as producing a rounded corner with decorative bead at lower depth settings, which lets you choose between a plain roundover or an added detail line in the same setup.
    • The bit is part of Bosch router bits in the profiling category, which aligns it with edge-forming tasks common in cabinet doors, furniture parts, and trim work.

    Roundover Router Bit Setup And Use Details

    This Bosch roundover router bit is identified as a router bit for rounding over, so setup focuses on edge passes rather than plunging cuts. The 1/4 inch shank diameter seats in a 1/4 inch router collet, which centers the bit for balanced rotation during profiling. With a 5/32 inch radius, depth setting directly controls how much of the curve engages the edge, which lets you tune from a light corner break to a fuller round within that radius. The note that a lower depth setting produces a rounded corner with decorative bead means that adjusting projection creates either a simple roundover or a roundover plus bead, giving two visual options without changing bits. The 13/16 inch diameter and 1-7/8 inch total length define how much bit extends beyond the baseplate, which helps plan passes along straight runs and around smaller panels.

    Using This Router Bit In Cabinet And Trim Work

    Where This Bosch Roundover Bit Performs Best

    This Bosch 85616M roundover bit sits in the profiling router bits class, so its role is shaping exposed edges on cabinet components and trim rather than rough cutting. The 5/32 inch radius suits applications where you want a softened edge that still reads crisp, such as face frames, shelves, or door rails, because the curve is modest and does not visually shrink the part. The 13/16 inch cutting diameter gives a defined path that tracks well along straight stock, which is helpful when running edges on longer parts. Its 1/4 inch shank allows use in routers and trim routers set up for 1/4 inch tooling, fitting many tools used for on-site edging or shop finishing passes. When the depth is set lower, the bit produces a rounded corner with a decorative bead, which adds a visual break line suited to furniture-style details on cabinet doors, aprons, or decorative panels.

    Profile Control For Repeatable Rounded Edges

    The 5/32 inch radius of this router bit sets a fixed curvature, so once you dial in the edge height, every pass repeats the same roundover, supporting consistent parts in batch work. Because the description specifies smooth, uniformly rounded edges, the geometry is aimed at leaving an even surface along the curve, which reduces leveling work between pieces that share the same profile. The lower depth setting option that produces a decorative bead gives two profiles from one Bosch roundover router bit, so repeating that depth setting yields matching bead-and-round edges across a run of doors or trim. The compact 1-7/8 inch length and 13/16 inch diameter also help with control when following narrow rails or shorter workpieces, because the bit mass stays closer to the collet. Within Wurth Baer Supply's woodworking focus, this combination of defined radius, controlled diameter, and 1/4 inch shank supports profiling workflows in cabinet and furniture production.

    Common Questions About This Bosch Router Bit

    What type of work is this Bosch roundover router bit designed for?

    This Bosch roundover router bit is classified under router bits for profiling and rounding over, so it is intended for shaping and softening exposed edges on cabinet, furniture, and trim components.

    What edge shape does the 5/32 inch radius produce?

    The 5/32 inch radius produces a modestly curved edge that breaks sharp corners while preserving overall part size, which suits shelves, frames, and door parts needing a softened but defined edge.

    How does the lower depth setting affect the profile?

    The lower depth setting on this router bit produces a rounded corner with decorative bead, so a single setup can provide either a simple roundover or a beaded edge depending on projection.

    What does the 13/16 inch diameter mean in use?

    The 13/16 inch diameter defines the cutting circle, which affects how much of the edge area is engaged during a pass and how close you can work near adjacent details or joinery.

    Which routers does the 1/4 inch shank fit?

    The 1/4 inch shank fits routers equipped with a 1/4 inch collet, aligning with many trim and mid-size routers commonly used for cabinet and finish profiling work.

    Why does the overall length of 1-7/8 inches matter?

    The 1-7/8 inch overall length keeps the cutting edges relatively close to the collet, supporting better control and stability when profiling smaller parts or narrow trim.

    Select This Bit For Controlled Rounded Edges

    This Bosch 85616M roundover router bit from Wurth Baer Supply combines a 5/32 inch radius, 13/16 inch diameter, and 1/4 inch shank to support controlled profiling passes on cabinet and furniture parts. The ability to produce either a smooth roundover or a rounded corner with decorative bead through depth adjustment adds flexibility for trim and door work. Selecting this router bit aligns tooling with edge-shaping tasks where uniform, rounded profiles contribute directly to the finished look of your woodworking projects.
