Ultra-Shear Big Bowl Router Bits
Maximum Efficiency and Depth for Larger Projects
Ultra-Shear Big Bowl Router Bits are designed for woodworkers who need to create deeper recesses and larger, smooth transitions in their projects. Featuring a 3-flute design, these bits achieve 50% more cuts per inch compared to standard 2-flute bits, ensuring faster, cleaner results. With an overall length of 2-7/8", Ultra-Shear Big Bowl Bits allow for deep cutting without the need for shaft extensions. Their full 1" cutting diameter clears out material faster, making them perfect for projects such as serving bowls, divided charcuterie boards, and holiday candy dishes.
Versatile Corner Radius Options
Available in four different corner radii—1/8", 3/16", 1/4", and 5/16"—Ultra-Shear Big Bowl Bits give you the flexibility to create the perfect radius for your project. Whether you're designing bowls, trays, or other custom woodworking pieces, these bits provide smooth, professional finishes with each pass.
Pattern-Following Precision and Easy CNC Use
Equipped with pattern-following bearings, these bits allow you to use commercially available templates or create your own custom patterns. The beauty of this system is that what you see in your template is exactly what your project will look like—no need to account for offset issues common with template guide bushings. For CNC users, the pattern-following bearings are easily removed, allowing seamless transitions to digital cutting.
Perfect for Deep Recesses and Smooth Transitions
Not only can these bits handle larger, deeper recesses, but they also excel at extending the depth of an existing pocket. By following the edge of a recess with the bearing, you can increase the depth and create a soft radius transition from the sidewalls to the bottom, resulting in a smooth, professional finish.
Innovative Carbide Head Design for Superior Performance
Ultra-Shear uses a hybrid design borrowed from the metal-cutting industry, merging solid carbide cutting performance with steel shank economy. Our "Carbide Head" bits feature a solid carbide blank brazed to a durable steel shank. The 3-flute spiral cutting pattern is then precision-ground onto the carbide head, providing the cutting efficiency of solid carbide spirals for less.
American Made Quality
Like all Woodpeckers products, Ultra-Shear Big Bowl Bits are proudly made in our Strongsville, Ohio facility. Whether you're a hobbyist or a professional, Ultra-Shear Big Bowl Bits offer unparalleled performance and value.
