Precision Twist C29HX10 29 Piece Purple & Bronze High Speed Steel Jobber Drill Set Fractional 135 Degree Split Point 091010

This Precision Twist C29HX10 jobber length drill bit set contains 29 high-speed steel drill bits, including inch sizes 1/16 Inch through 1/2 Inch in 1/64 Inch increments, with a purple and gold oxide finish and a 135-degree split point for general-purpose applications on a range of materials. High-speed steel (HSS) provides hardness for wear resistance, and the purple and gold oxide finish provides additional wear resistance compared to an uncoated drill bit. Compared to standard drill bits, these tools have a thicker web for increased strength and rigidity. The self-centering 135-degree split point penetrates hard material without a pilot hole and produces smaller chips, which are less likely to clog a hole than a 118-degree point. These jobber length drill bits have a drilling depth up to four times their diameter. The round shank accommodates most drill chucks. The set comes in a metal index case with labeled compartments for identification and organization. Drill bits conform to American National Standards Institute (ANSI) standards.
