JGZUI 2-Degree Spiral Flush Trim Router Bit Set Designed for clean, chip-free edge trimming and template routing. The spiral cutting edges are set at a 2-degree shear angle, slicing through wood fibers rather than tearing them for a superior finish. The enclosed top bearing follows templates and straight edges with precision, making it easy to achieve consistent flush cuts every time. C3 tungsten carbide cutters stay sharp through heavy use, while the Teflon-coated No. 45 carbon steel body resists heat and corrosion. The 1/4" shank fits standard routers and trim routers. Whether you are trimming laminate countertops, flushing cabinet veneers, or copying templates for furniture projects, this bit delivers smooth, professional results. Available in four popular cutting diameters and a 4-piece set, all featuring a 30mm cutting length and 1/4" shank.
