    Countersinks for Rivets

    Tough and wear resistant, these countersinks last at least twice as long as high-speed steel. They can also run up to 25% faster at higher temperatures without chipping on hard materials, such as nickel.
    Titanium Nitride (TiN) Coated—Withstand heat, corrosion, and abrasion better than uncoated and black oxide countersinks, so they stay sharp over longer periods.
    Number of Flutes—Countersinks with fewer flutes reduce chatter, so you can run them at high speeds. Countersinks with a higher number of flutes remove more material per revolution, leaving a smoother finish and extending tool life.
