Ultra-Shear 3-Flute Flush Trim Router Bits with Template Bearing
Faster Pattern Routing or Better Finish? You Choose.
Pick up the pace on pattern routing projects or improve the surface finish—the choice is yours when using Ultra-Shear's 3-Flute Spiral Flush Trim Bits. The 3-flute geometry generates 50% more cuts per minute, giving you the flexibility to either feed faster while maintaining the same number of cuts per inch or slow down and achieve an ultra-smooth finish requiring minimal sanding.
Options to Match Your Project
Ultra-Shear offers these versatile bits in both up-cut and down-cut versions, with cut lengths of 3/4", 1", and 1-1/4". The super-sharp spiral flutes handle intricate work with ease and leave behind clean surfaces. The 1/4" tall pilot bearing is precisely matched to the cutter diameter, delivering flawless pattern routing even on small, intricate shapes with tight inside corners. The range of cut lengths allows you to match the bit precisely to your material thickness.
Up-Cut or Down-Cut?
Up-Cut bits pull chips toward the router—upward when used hand-held and downward when used in a router table—making them ideal for solid wood. Down-Cut bits push chips away from the router. When used in a router table, they require careful handling but excel at leaving a clean top surface, especially on plywood with thin face veneers.
American Made Quality – Built to Last
Ultra-Shear Spiral Flush Trim Bits are made using premium solid carbide blanks and ground on state-of-the-art CNC equipment with ultra-fine grinding wheels. This delivers unmatched sharpness, durability, and performance. As with all Ultra-Shear products, these router bits are made in our Strongsville, Ohio, facility, ensuring factory-direct, American-made quality.
