Ultra-Shear 3 Flute Compression Router Bits with Short-Up Cut Options
Faster, Smoother Cuts with Flawless Edges
Ultra-Shear's 3-flute compression router bits are designed to deliver faster, smoother cuts with flawless top and bottom edges. Made from solid carbide, these bits combine up-cut tips with down-cut shanks, ensuring beautiful, chip-free cuts on both sides of your material. Adding a third cutting flute gives you the option to increase your feed rate or get more cuts per inch, enhancing your efficiency and precision.
Versatile Performance in Various Applications
These bits perform flawlessly in CNC machines of any size, as well as in hand-held routers and router tables. While compression bits are typically chosen for plywood and MDF work, Ultra-Shear's design allows them to cut solid wood perfectly too. The unique combination of up-cut and down-cut flutes ensures a smooth finish on both the top and bottom surfaces of your projects.
Two Cut Length Options for Maximum Flexibility
Ultra-Shear offers these bits in two cut lengths: 1-1/4" and 1-5/8". Both lengths are available with standard or short up-cut sections. The short up-cut feature provides the advantages of compression cutting geometry in materials as thin as 1/4". This allows the down-shear cutting action to engage the top surface during shallow cuts, making these bits extremely versatile for various project requirements.
Proudly Made in the USA
All Ultra-Shear Solid Carbide bits are manufactured in Woodpeckers' Strongsville, Ohio facility. We take pride in our American-made products and are confident you won't find better quality for less.
