1 Milling Bit D0.2-D0.9mm Micro Flat End Mill Carbide 2 Flutes CNC Router Bit Nano Blue Coated CNC Machine Milling Cutter Description: Under the condition of ensuring the chip space, the large core diameter design is adopted to enhance the rigidity of the tool, and the rigidity of the tool and the strict chip discharge performance and the scientific groove control are made, so that the cutting and chip removal of the tool are more stable. Features: 1: Multi-layer nano-coating:It can directly perform high-speed roughing to fine processing for heat-treated materials below 58, reducing the number of tool changes and improving machine tool processing efficiency. 2: The new fine-grained tungsten steel base material has high wear resistance and strength, and is specially designed for high-hardness and high-speed cutting applications. 3: Can fit on mostCNC machine,Engraving machine, High speed machine. Specification: Type: 2 Flutes Flat End Mill Material: Tungsten Carbide Coating: Nano Blue Coated Shank: 4mm Cutting Diameter: 0.2mm 0.3mm 0.4mm 0.5mm 0.6mm 0.7mm 0.8mm 0.9mm Overall Length: 50mm User Tips In order to obtain a better cutting surface and extend the life of the tool, be sure to use a tool holder with high precision, high rigidity and good dynamic balance. 1. Before usingthis tool, please measure the tool yaw and the tool yaw accuracy exceeds 0.01MM, please correct it before cutting. 2. The shorter the length of the tool extension clamp, the better, if the extension of the tool is extended, please reduce the rotation speed, feed speed or cutting amount. 3. If abnormal vibration or sound is generated during cutting, reduce the spindle speed and cutting amount until the condition is improved. 4. Steel cooling is best applied by spray or jet to maximize the effect of high aluminum titanium. Insoluble water-soluble cutting fluids are recommended for stainless steel, titanium alloys or heat resistant alloys. 5. The cutting method depends on the influence of workpiece, machine and software. The above data is for reference only. After the cutting condition is stable, the feed rate will be increased 30% to 50%. Note Please allow 1-3mm error due to manual measurement.
