Meet the Freud 08-136 5/8" (Dia.) Double Flute Straight Bit with a 3/8" shank—the go-to choice for woodworkers who demand precision, speed, and a flawless finish. Built from Freud’s carbide-tipped line, this bit is engineered to handle demanding routing tasks with consistency across materials.

• 5/8" diameter, 3/8" shank provides a robust, stable cut and generous groove capacity while staying compatible with a wide range of routers.
• Double flute geometry paired with precise hook and shear angles delivers fast material removal and a smooth, tear-free finish in hardwood, softwood, plywood, and composites.
• Carbide-tipped design offers excellent durability and long life, making it ideal for frequent routing and repeated use on projects.
• Relieved tips enable efficient plunge cuts, reducing loading and improving control when starting cuts into the workpiece.
• Versatile mounting designed for CNC, hand-held and table-mounted routers, so you can tackle precise grooves, edge-routing, and general routing tasks on any setup.
• Wide applicability perfect for grooves and slots, edge profiles, and dado-like cuts on cabinetry, furniture, shelving, and projects that require clean, repeatable edges.

Why this bit stands out: the 5/8" diameter creates robust, wide grooves and stable guidance for large-radius edges, while the double flute design accelerates cutting without sacrificing edge quality. The combination of carbide tips, relief on the tips, and smart geometry means fewer passes, less chipping, and results you can trust on every cut.

Ideal use cases

• Grooving and edge-routing on boards for shelves, cabinet backs, or panel assemblies
• dado-like joint preparation and wide-slot routing in plywood and solid wood
• Precision channeling for hardware inserts or decorative edging on furniture projects
• Consistent, repeatable cuts in CNC or manual-router setups for production work

Who this is for: professional woodworkers, cabinet makers, and serious hobbyists who value durable tooling, dependable finishes, and versatile performance across woods and composites. If you regularly work with wide grooves or require clean edges in mixed-material projects, the Freud 08-136 is engineered to deliver.
