| High processing efficiency: the edge of the cutters is hard and sharp with a coating. Process heat treatment materials under 32 high speed, reduce changeover times and improve production efficiency. Cutting edge design: The bottom of the cutter is U-shaped, the large front angle effectively reduces cutting resistance, sharp and durable, convenient for removing chips and further improving machining efficiency. Usage: The milling bits are suitable for milling lateral, final milling, finish machining, etc. Applies to carbon steel, alloy steel, tool steel, cast iron, titanium, aluminum, etc. A set of countersunk bits including: 8 different sizes of cutters to meet your needs, 1/16" = 2mm, … | |
