1/8" Super Primalloy Cryo-Gen N Maintenance Length Drill Bit - 3 Pack by Super Primalloy

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. Reduced overall length by 15% enhances rigidity and resistance to breakage. Cryogenic treatment minimizes brittleness and extends tool life. Dark gold surface treatment provides excellent lubricity for increased drill life. Modified flute and web design boosts strength and durability. Premium 'M' series alloy steel construction offers exceptional wear resistance and longevity. Proudly made in the USA.
