Uxcell 4mm Shank 0.9mm x 8mm Solid Carbide Uncoated 2 Flute Square End Mill Cutter

Made of fine grain carbide it has high hardness (HRC90) high strength and wear resistance. With good milling and cutting performance carbide can run at higher speed than high-speed steel. The passivation treatment greatly increases corrosion resistance and wear resistance. Suitable for cutting materials with hardness below HRC55 such as aluminum aluminum alloy copper magnesium alloy etc.. The clearance part is the same as the cutting diameter specially designed for machining deep holes and deep grooves. Used for groove machining side milling and finishing. Features square end cut 2-flute design large and spiral chip space design for fast and clean chip removal. Sharp cutting edge provides smooth cutting. Features just the base substrate without any coatings good for general purpose cutting in wide ranges of applications. Use on CNC machining centers CNC machine tools precision engraving machines and other equipment. Universal chamfered round shank for easier clamping and stable cutting process.The longer the length of the tool clamped by the chuck the better. Tips: If the clamping length is shorter you need to lower the feed rate and cutting speed to reduce vibration and extend the tool life. Combined with the material to be processed select an appropriate feed rate and cutting speed to improve the tool life and obtain better processing accuracy and performance.
