Bosch roundover bit 1/8 radius gives you a dedicated router bit for producing smooth, uniformly rounded edges, so edge profiles look consistent from part to part on a job. This 2 inch x 1/8 inch radius corner roundover bit is built as a profiling router bit, so it is suited to shaping exposed edges rather than bulk material removal. The 2-flute design cuts with two edges each rotation, which supports a cleaner cut path around corners and along grain. A 1/4 inch shank matches common light and mid-size routers that accept 1/4 inch bits, so it fits into typical trim and detail routing setups. The bit is identified as Bosch part 85290M, so matching it again for repeat work or replacements stays straightforward across projects.
The 1/4 inch shank on this router bit is designed to seat in 1/4 inch router collets, which lets it work with trim and mid-size routers commonly used for profiling. The design allows a lower depth setting to produce a rounded corner with a decorative bead, so you can control how much of the bead shows by how deep the bit is set relative to the workpiece edge. This lower depth setting capability means the same bit can create either a simple rounded corner or a more decorative rounded corner with a bead, depending on the routing setup. Because it is a profiling bit for smooth, uniformly rounded edges, it fits naturally into finishing passes rather than early roughing work.
This Bosch 2 inch x 1/8 inch radius corner roundover bit functions as a profiling tool in woodworking, so it suits tasks where visible edges need a controlled round. The 1/8 inch radius is sized for relatively small edge breaks, which matches work on cabinet doors, drawer fronts, shelves, and trim where a subtle softened corner is preferred. Because the bit is identified as a router bit in the profiling category, it naturally belongs in setups focused on shaping the final edge rather than cutting joinery. The smooth, uniformly rounded edges described by the manufacturer show that this cutter is intended to leave a finished-looking profile directly off the router, which helps keep edge work efficient on repeated parts.
The 2-flute layout further supports this profiling role, since two flutes share the cut around the rotation and help maintain a steady feel as the bit runs along edges. On straight runs and gentle curves, this construction is suited to maintaining a consistent contact pattern with the work, so the operator can focus on feed rate and guidance rather than roughness from the cutter. With a 1/4 inch shank, the bit matches trim routers that are often used one-handed for detail work, so it fits naturally into on-site adjustments and shop finishing passes on smaller components.
The Bosch 85290M part number ties this router bit to a defined 1/8 inch radius roundover profile, so shops can return to the same cutter when they need the same edge detail on different projects or replacement bits. This defined profile helps keep runs of cabinets, doors, or panels visually consistent, because the radius and bead potential stay the same each time the bit is used. The ability to use a lower depth setting to produce a rounded corner with a decorative bead adds flexibility to that repeatability: the same bit can produce a plain round or a round with a bead simply by adjusting how deeply it engages the edge.
Because the bit is described as producing smooth, uniformly rounded edges, its geometry is tuned for finishing rather than aggressive stock removal, which helps reduce visible tool marks that would otherwise need extra sanding. The 2-flute design also contributes to this consistent finish, since two cutting edges share the work and support a balanced cut. With the 1/4 inch shank fitting routers that accept that shank size, the bit can stay in a dedicated trim router for edge profiles, so operators can repeat the same setup day to day without changing collets or tooling.
The Bosch 85290M router bit creates smooth, uniformly rounded edges with a 1/8 inch radius, which softens corners while keeping the profile controlled for cabinetry and similar work.
The Bosch roundover bit 1/8 radius, at a lower depth setting, produces a rounded corner with a decorative bead, giving you a more detailed edge from the same cutter.
This router bit has a 1/4 inch shank, so it fits routers that accept 1/4 inch bits, which is common for trim and mid-size routers used for profiling.
The 2-flute design means two cutting edges share the cut, which supports smoother passes and reduces visible marks on rounded edges.
The 2 inch x 1/8 inch radius corner roundover bit is sized for modest edge breaks, providing a controlled, subtle round suitable for many cabinet and trim parts.
The Bosch 85290M part number uniquely identifies this 1/8 inch radius roundover bit, helping you match the same profile for future work or replacements.
This Bosch roundover bit 1/8 radius is built as a profiling router bit for smooth, uniformly rounded edges, so it suits shops and installers who need a repeatable, modest corner round. The 1/4 inch shank fits typical routers that accept that size, keeping the bit compatible with common trim routing setups. With its 2-flute construction and 1/8 inch radius profile, the bit supports consistent, controlled edge work on cabinetry and similar components. For projects where a defined roundover look matters, the Bosch 85290M part number provides a clear reference when selecting this cutter from Wurth Baer Supply.
