Cryo-Gen N Letter Industrial Length Drill Bit by Super Primalloy

Robust Super Primalloy construction ensures durability. A patented multi-phase cryogenic treatment refines the drill's molecular structure, enhancing longevity and reducing stress fractures. The 'N' series nitride treatment hardens cutting surfaces for superior edge retention and faster hole creation. The 135° split point design facilitates easier penetration into high-tensile materials. Cryogenic treatment also stabilizes the molecular structure, reducing brittleness and extending tool life. A dark gold surface treatment provides excellent lubricity for increased drill life. Modified flute and web designs enhance strength and durability. The superior 'M' series alloy steel construction offers exceptional wear resistance and longevity. Flatted shanks minimize slippage in the drill motor and prevent damage. Proudly made in the USA.
