Right hand (clockwise rotation) cutting direction. Standard two flute design. Standard spiral, helical flutes. 118 °s; normal point suitable for most normal, general purpose, drilling applications. 135 °s; split point suitable for drilling high tensile strength, low machinability, ferrous materials, such as tougher alloy and harder stainless steels. Have a heavier web construction that offers greater rigidity and strength to better resist any increased torque. Self-centering and reduces the thrust required in drilling tougher materials.
