Description
Drill America D/ASTCO series cobalt steel screw machine length drill bit. Manufactured to National Aerospace Standard 907. 135 degrees split point is self-centering and reduces thrust. Ideal for portable or machine drilling. Short, rugged construction performs well in high tensile strength materials like PH stainless steel, inconel, and titanium.

Key Features

Cobalt steel tools are similar to high-speed steel, but with more cobalt for improved performance when cutting harder metals such as stainless steel or nickel alloys

Gold oxide is a thinner oxide surface treatment than black oxide typically used to identify cobalt steel tools; performance is similar to uncoated tools

Round shanks allow use with a wide variety of toolholding systems

When run in a counterclockwise direction (right-hand cut) spiral fluted tools evacuate chips up and out of the cut to reduce clogging

Ideal for portable or machine drilling
