The 1/2" Shank Carbide Arc Filling Router Bit stands as a premium precision tool engineered to craft seamless arc-shaped recesses and intricate decorative profiles across diverse woodworking projects. Forged from solid micrograin carbide (C6 grade)—renowned for its exceptional hardness (92 HRC) and wear resistance—this router bit integrates a TiCN (titanium carbonitride) coating that enhances surface hardness by 40% compared to uncoated alternatives. This advanced construction makes it uniquely suited for shaping dense hardwoods like oak and mahogany, as well as laminates and composite materials prone to splintering. The 1/2" shank delivers superior stability in high-torque routers and CNC machining centers, while its specialized arc filling design ensures smooth, vibration-free cuts when forming curved edges, inlays, or structural joints requiring precise curvature.

Arc Profiling Precision: Boasts ±0.001" tolerance in curvature consistency, ensuring uniform arcs across multiple workpieces—critical for matching cabinet door panels or furniture components.
Multi-Material Versatility: Effortlessly cuts through hardwoods, softwoods, plywood, MDF, and acrylic, with the TiCN coating reducing resin buildup in pine and cedar.
Heavy-Duty Stability: The 1/2" shank minimizes deflection by 60% compared to 1/4" shanks during aggressive routing, making it ideal for industrial production lines.
Heat Management: TiCN coating dissipates heat 30% faster than standard coatings, preventing wood burning in deep cuts and extending tool life by 50% in continuous use.
Tool Compatibility: Seamlessly integrates with standard collets in routers from brands like Festool, Bosch, and DeWalt, supporting quick setup in both handheld and table-mounted configurations.
Furniture Design: Creates arched door panels for wardrobe cabinets, curved drawer fronts in mid-century modern furniture, and inlaid arc patterns for table tops.
Cabinetry: Forms smooth radius edges on kitchen countertop overhangs, bathroom vanity shelves, and open shelving units for a modern, child-safe finish.
Woodworking Artistry: Essential for marquetry and intarsia projects, shaping intricate curved joints in decorative wall art and heirloom-quality furniture.
Restoration Work: Precisely fills gaps in antique furniture with custom-matched arc profiles, preserving original aesthetics while reinforcing structural integrity.
Q: Can this bit be used for metalworking applications?
A: No. It is specifically engineered for wood and non-ferrous materials. For metal, use carbide end mills designed for ferrous/non-ferrous machining.
Q: What feed rate is recommended for different wood types?
A: For hardwoods (oak, maple): 40–60 IPM; for softwoods (pine, cedar): 60–80 IPM; for composites: 50–70 IPM to prevent delamination.
Q: How to maintain the TiCN coating for longevity?
A: Clean with a soft bristle brush and compressed air after use. Avoid harsh solvents or wire brushes. Re-coat professionally after 3–4 sharpening cycles.
