Ultra-Shear Compact Bowl Router Bits
Delicate Precision for Small-Scale Projects
Ultra-Shear Compact Bowl Router Bits are a more refined option for creating beautiful, intricate projects. With a 1/2" cutting diameter and smaller bottom-radius options, these bowl bits deliver a distinct and delicate look compared to larger 7/8" or wider bowl bits. Perfect for making divided charcuterie boards, nightstand valets, coasters, desk organizers, and holiday candy dishes, these bits are ideal for countless small-scale woodworking projects.
Precision Cutting Compatible With Shaper Origin or Templates
The Ultra-Shear Compact Bowl Bits are available with 8mm shanks, compatible with Shaper Origin, offering precise digital control, or 1/4" shank versions for traditional router setups. When working with a template, there’s no offset to worry about as with guide bushings—what you see in your template is exactly what your project will look like. This makes them perfect for creating custom shapes with unparalleled accuracy.
Smooth Finishing for Recesses and Pockets
Beyond templated work, bowl bits are excellent for cleaning up recesses and pockets. For example, after drilling a hole with a Forstner bit, you’re often left with an unsightly center spur and sharp groove. A quick pass with a bowl bit erases the center hole and creates a smooth radius around the perimeter for a professional finish.
Innovative Hybrid Design for Superior Cutting Performance
Ultra-Shear’s innovative design, delivers spiral bowl bits with unmatched efficiency. Instead of wasting time and material grinding down a solid carbide bit, Ultra-Shear brazes a solid carbide head onto a steel shank and turns the entire assembly for perfect concentricity and superior cutting geometry. This hybrid approach offers the precision of solid carbide spirals for less.
Multiple Radius Options for Custom Projects
The 1/4" shank Compact Bowl Bits come with corner radii of 1/16", 1/8", and 3/16", all featuring a 3/8" cut length. The 8mm shank versions offer radii of 1mm, 2mm, and 3mm, making them perfect for detailed digital work, compatible with Shaper Origin. You can purchase individual bits or save with a complete set of either 1/4" or 8mm shank bits, giving you the flexibility to tackle a variety of projects.
American Made Quality
Like all Woodpeckers products, Ultra-Shear Compact Bowl Router Bits are proudly made in Strongsville, Ohio, using state-of-the-art CNC grinding equipment.
