The Precision Twist 2ACO jobber-length drill bit is a 135-degree, split-point, heavy-duty, round shank drill bit made of HSS and cobalt with a gold oxide finish. They meet NAS 907 Type J aircraft industry specifications for heat resistance and use for drilling hard, tough materials. Best performance with drilling into hardened, tempered alloy steel, nodular graphite malleable cast iron, and alloyed titanium and nickel. It is suitable for drilling to a depth up to four times the diameter of the drill. The shank diameter is the same as the drill size. While the 2ACO series was designed for aircraft industry, they also work well for drilling into a variety of materials. The 135-degree split-point drill geometry ensure an accurate hole by reducing walking when the hole is started. The finish retains lubricants to aid in wear resistance and chip flow. The 2ACO series has a type N flute form, with a regular helix angle of 21 to 34 degrees. The gold oxide is a low temperature heat treatment which reduces grinding stress within the tool, and has an appealing, easy-to-identify gold color. Gold oxide is commonly used to identify cobalt steel tools. Spiral flutes act as a passageway for chip extraction from the hole and for coolant to enter the hole. Right-hand twist brings chips up and away from the cutting edge. and away from the cutting edge. They are made to DIN 338 and NAS 907 industry standards, which help ensure that drill bits around the world conform to the same specifications.
