Amana Upcut Spiral Plunge Router Cutters 1/4" Shank

These spiral-flute bits combine a shearing action for a clean, accurate cut with an augering action for chip clearance. The "up-cut" does as it says and cuts from the bottom, pulling chips upwards as it cuts. This enables deeper penetration while reducing stress on the tool, making this perfect for mortising. These router bits are manufactured in solid carbide for long tool life, even when used in abrasive material. The polished flutes and razor sharp cutting edges produce superior results. These bits are primarily for CNC use and are ideal for production settings. They are great for cutting grooves and dado cuts, and are excellent for particleboard, plywood and laminate. Suitable for CNC routing, handheld routers and router tables.
