Robust Super Primalloy construction ensures durability. Multi-phase cryogenic treatment at -300°F enhances molecular structure, reduces stress, and boosts longevity. 'N' series nitride treatment hardens cutting surfaces for superior edge retention and faster hole creation. Heavy-duty 135° split point design simplifies center punching and improves penetration in high-tensile materials. Cryogenic treatment stabilizes molecular structure, reducing brittleness and extending tool life. Dark gold surface treatment provides excellent lubricity for increased drill life. Modified flute and web design boosts strength and durability. 'M' series alloy steel construction offers exceptional wear resistance and longevity. Flatted shanks minimize slippage in the drill motor and protect the drill and chuck. Proudly made in the USA.
