Reduced length enhances rigidity, strength, and resistance to breakage. A patented deep thermal cycle, down to -300°F, refines the molecular structure, reduces stress, and boosts durability. Cryogenic treatment minimizes brittleness and extends tool life. Nitride treatment hardens cutting surfaces for superior edge retention, faster hole creation, and longer service life. Left-hand rotation can back out fasteners, eliminating the need for screw extractors. A super heavy-duty 135° split point eliminates center punching. Premium 'M' series alloy steel offers exceptional wear resistance and longevity. Precision-ground flats on the shank prevent slippage and damage. (Sizes under 3/16" lack flatted shanks). Manufactured in the U.S.A.
