Ultra-Shear 1/4" Shank, 1/4" Cut Diameter, 2-Flute Solid Carbide Spiral Router Bits
Delivering Smoother Cuts
Spiral bits deliver smoother cuts, because some part of the bit is always in contact with your material, where brazed bits have an interrupted cut.

Flexibility with 1/4” Shank
These 1/4" bits are perfect for grooves, dados rabbets and mortises. The 1/4" shank gives you the flexibility to use them in smaller routers.
Versatile Range of Cutting Lengths
The Ultra-Shear 1/4" bits come in a range of cutting lengths: 3/4", 1", 1-1/4", 1-1/2", and 1-3/4". These variations allow you to choose the perfect bit for your specific project needs.
Excel at Deep Mortising Jobs
The long shank and extended cut length of these bits excel at deep mortising jobs, particularly when used in CNC or horizontal router systems like the Multi-Router or compatible with PantoRouter. Always use the shortest cut length necessary for your cuts to achieve the best results and maintain tool longevity.

Choosing Between Up-Cut and Down-Cut Bits
Up-Cut Bits: Ideal for dadoes, slotting, and full-edge cutting in solid wood, Up-Cut bits effectively pull chips out of the kerf.
Down-Cut Bits: Perfect for rabbeting and working with cabinet-grade plywood, Down-Cut bits slice down into the material, preventing surface fibers from lifting.
Made in the USA
All Ultra-Shear Solid Carbide bits are manufactured in Strongsville, Ohio facility. We use high-quality carbide blanks, ultra-fine grinding wheels, and advanced CNC grinding equipment to produce great American-made router bits.
