High Quality: High Quality: The Genmitsu end mills are made of Tungsten Carbide Steel and 0.2um ultra-fine 0.2μm tungsten carbide steel alloy that can keep continuous machining 800 minutes. Moreover, its Nano Blue Coating provides high hardness, and heat resistance enables the tool's cutting edge to retain crucial sharpness and lubricity. This provides longevity and produces cutting results of the highest quality.
Down Cut Advantage: Downcutting bits press the chips and the material back into the cut, thus leaving a nice finish on the top surface of your material. Generally used for smoothly downcut groove and slots, mortises, cycles, and dados, plunge cut leaves with a clean edge and top surface, better than straight bits.
