Amana Upcut Spiral Plunge Router Cutters with Spektra 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. These router bits are excellent for cutting the following materials: Laminate Melamine Melamine Particle Board MDF Veneered Plywood Wood With a brilliant distinctively-tinted coloring, the Spektra™ nACo nanocomposite coating provides additional improvements in four critical aspects of router tooling. • nACo coating is a micro-thin ceramic coating which enables the tool's cutting edge to retain crucial sharpness and lubricity. This provides longevity and produces cutting results of the highest quality. • Coating prevents high heat and oxidation which is detrimental to cutting tool performance. • Multi-colored hues, while attractive, will dissipate upon use and yet coating will remain fully effective. • nACo offers approximately 4,500 Vickers for impressive solid hardness on cutting areas of the tool, for an increase up to 2.5 times compared to uncoated bits. Note: Blue based color dissipates immediately upon use. nACo® nanocomposite coating will not wear off. Suitable for CNC routing, handheld routers and router tables.-bg
