Uxcell Carbide Flute End Mill CNC Router Bit Cutting 4mm x 22mm

Made of carbide (tungsten steel), the end mill is wear resistance, good toughness, heat resistance, higher hardness but is more brittle. Carbide can run at higher speed than high-speed steel. Carbide material with good milling and cutting performance, ensures high work efficiency. Spiral chip space design for fast and clean chip removal. Cutting edge provides smooth cutting and no glitches. Upcut end mills can direct chips up and away from the milling area, leaving an unobstructed path to prevent tool breakage and extends the tool life.
