MLCS Tri (TM) carbide-tipped router bits are at the vanguard of routing technology. Larger cutters with an extra cutting blade (versus standard 2-flute bits) save time by allowing more aggressive cuts, and therefore, fewer passes. These 1/2" shank bits can be run at reduced speeds, helping to eliminate burning on problem woods, such as, cherry, oak, and others. The August '06 Workbench Magazine Review states: "While two flute bits can leave cutter marks...these three-flute bits produce consistently smooth cuts." TripleWing (TM) Flush Trim Bits are for use in trimming laminates and pattern routing. 1/2" Large Diameter, 2" Cutting Length, 1/2" Shank
