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.
