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.

1.Premium 40Cr steel with heat treatment improves core strength for maximum durability and extended life.
2.Hardened, premium carbide insert tip is strong and stays sharp longer for finer material break up and easier drilling.increases
3.strength and durability.
4.Copper braze material gives high heat resistance for reduced tip loss,Carbide tip securely embedded in the steel body.
5.Fold spiral flute (S4) for rapid drilling dust removal.
6.With even less vibration and more precise guiding, the stability and
7.service life of the drill bit are increased.
