1,Precise dimension,long life and high efficiency.
2,High-speed steel (HSS) provides hardness for wear resistance
3,Black oxide finish reduces wear while promoting chip and coolant flow on ferrous materials
4,Self-centering 118-degree notched point penetrates material without a pilot hole more easily than a conventional point, and maintains a sharp cutting edge
5,Morse taper shank allows the tool to be inserted directly into the machine's spindle to facilitate high-torque applications such as large cut diameters
6,When run in a counterclockwise direction (right-hand cut) spiral fluted tools evacuate chips up and out of the cut to reduce clogging
7,Designed to perform in a broad range of materials in the iron and steel families
8,Spiral flutes are constructed with a higher flute angle to remove chips more easily.
Made from High Speed Steel, Right hand cutting. Standard two flute design.
General purpose, normal duty drills designed for drilling holes in a variety or normalsteel, cast iron, and other ferrous and non-ferrous metals and alloys.
Have a normal 118 degree drill point angle suitable for a variety of drilling applications and conditions.
