1、HIGH HARDNESS COATING: The router bit features a high hardness and heat resistan blue coating that enables the tool cutting edge to maintain vital sharpness and lubricity, resulting in the perfect cutting results 2、WEAR RESISTANT AND BURR FREE: The coating of the milling body better removes chips and reduces friction. To prevent the build up of wood chips, resins and bitumen, the cutting material should be free of burrs 3、INCISIVE AND FAST: Double bearing flush trim bit bring incisive cutting, smooth rotation, quick operation, high hardness 4、DURABLE AND RUGGED: The flush trim bit has a strong tungsten steel alloy case and no backlash design. Tungsten carbide tip particle quality can improve strength, with good wear resistance and long service life 5、MULTI FUNCTIONS: The main functions of milling cutter are cutting, three dimensional sag angle, slotting. The blade is incisive and smooth, suitable for trimming, 3D free angle and sashing 6、SUITABLE OBJECT: The line flush trim bit is suitable for wood, medium density fiberboard, particle board, plywood and other compact panels
