Infinity Tools 1/2" Shank Roundnose (Core Box) Router Bit – Create Smooth Curves, Decorative Grooves & Details

Add smooth, flowing details to your woodworking projects with our premium-quality 1/2" Shank Roundnose Router Bit, also commonly called a Core Box Router Bit. The fully rounded cutting profile is ideal for routing decorative grooves, flutes, veins, and coves in furniture, cabinetry, doors, drawer fronts, signs, and other woodworking projects.

With its large 1-1/4" radius and 3/4" cutter height, this bit is also an excellent choice for rounding and shaping the interior edges of bowls, trays, boxes, and other recessed areas. The 1/2" shank provides excellent rigidity and stability when making larger, more demanding cuts.

For even more versatility, Item 14-690B includes a top-bearing kit with stop collar and Allen key. The bearing diameter matches the cutter diameter, allowing the bearing to follow a template or existing surface for accurate template-guided routing and decorative shaping.

Why use a 1/2" shank instead of a 1/4" shank?

A 1/2" shank resists deflection and vibration better than a 1/4" shank, giving smoother, more accurate cuts — especially on larger profiles and in a router table.

The bearing diameter is 3/4", matching the cutter diameter.

Should I use this bit in a router table?

Yes, a router table is recommended for a bit this size, giving you better control and safety on larger profiles.
