steel twist drill bit

The steel twist drill bit is made of high quality high speed steel with heavy duty 135 breakaway points for self centering and thrust reduction. Gold and black finish, Drill Bit For Metal is used for drilling stainless steel and other hard metals. The high-speed steel Metal Drill Bit is suitable for most general-purpose applications, offering a combination of hardness and toughness for improved wear resistance. These round shank tools are ground on all three sides to reduce slippage of the Hole Cutter Step Drill Bits when used in drill chucks. When the Twist Drill Bit operates in a counterclockwise direction (right cut), the helical flute cutter ejects the chips upwards to reduce jams.
