Drill Bit Features: Cutting edge diameter: 3mm / 0.118"; round shank diameter: 3mm / 0.118"; cutting edge length: 29mm / 1.14"; overall length: 60mm / 2.36"; split point: 135 degree. Suitable for handheld drills, drilling machines, bench drills, machining centers, CNC lathes.. 4341 High Speed Steel: It contains high content of carbon and alloy elements, providing excellent cutting performance, high heat resistance, high hardness, wear resistance and durability. Good for applications requiring precise and efficient processing.. Black & Gold Finish: Premium black nitride and gold titanium dual coatings can apply lubricant better for smoother drilling and are more durable and corrosion resistant. The black and gold finish helps to extend the tool life.. Wide Applications: The drill bits can drill clean and accurate holes in stainless steel, cast iron, A3 steel, carbon steel, aluminum alloy, copper, wood and plastic. Sharp cutting edges provide neat and smooth cuts. Large spiral grooves facilitate the export of metal chips..
