JGZUI 3-Flute Straight Router Bit Set This 3-flute straight router bit is engineered for woodworkers who demand precision and durability. The C3 tungsten carbide cutting edge is brazed to a hardened No. 45 carbon steel body, delivering the sharpness to cut through hardwoods, MDF, and plywoods cleanly while maintaining its edge over extended use. The three-flute straight design produces smooth, accurate grooves with efficient chip removal - ideal for dadoes, rabbets, and flush-trimming operations. The Teflon-coated body reduces friction and heat buildup, preventing resin from sticking and extending the life of the bit between cleanings. Choose the shank size that matches your router: the 1/4-inch shank option fits handheld routers, trimmers, and engraving machines, while the 1/2-inch shank option offers extra rigidity for router tables and CNC applications. All bits feature a 30mm cutting length and come in a protective plastic box.
