1/2 inch (12.7 mm) end mill router bit for wood carving — built for large concave work Shank: 1/2 inch (12.7 mm) — fits routers and routers’ collets that accept a 1/2" shank. Cutting width: 2 1/2 inches (2.5 inches) — broad cutter for removing more material per pass. Profile: 2.5 inch radius concave cutter bit — produces a consistent, smooth concave surface ideal for bowls and hollows. Purpose: specifically designed as a router bit for big bowl carving and other large concave shapes. Why this bit solves common woodworking problems Faster roughing: the wide cutting width and concave profile let you remove material more quickly than narrow bits, reducing carve time on large bowls and hollow forms. Consistent contours: the 2.5 inch radius cutter creates uniform concave curves across the workpiece, minimizing the need for extensive hand sanding and reshaping. Router-ready compatibility: a 1/2 inch shank ensures secure, low-vibration installation in routers that accept 1/2" bits, improving control and finish quality. Key benefits at a glance Time savings on large projects thanks to greater material removal per pass. Cleaner, repeatable concave profiles for bowls, platters, and recessed panels. Simple installation and reliable routing with standard 1/2" collet compatibility. Designed specifically for woodworking applications that require large-radius concave cuts. Typical applications and use scenarios Big bowl carving: quickly rough and refine the interior curve of large wooden bowls while maintaining a consistent radius. Hollow forms and vessel making: create smooth, even hollows in turning blanks or stacked blanks for further finishing. Decorative concave panels and architectural details: produce concave recesses or sculpted panels where a 2.5" radius curve is required. Practical notes for use Use in routers or CNC machines equipped for 1/2" shanks and appropriate power for large-diameter cutting. Make multiple shallow passes rather than one deep cut to preserve tool life and achieve a smoother finish. Follow standard safety practices for routing: secure the workpiece, use proper feed rates, and wear appropriate protection. Specifications Shank diameter: 1/2 inch (12.7 mm) Cutting width: 2 1/2 inches (2.5 inches) Cutter profile: concave, 2.5 inch radius Intended use: router bit for big bowl carving and other large concave woodworking projects This bit is focused on large-scale concave shaping tasks where a consistent 2.5" radius and broad cutting width make carving faster and more predictable.
