    Even on hard and difficult-to-machine materials, these bits cut holes so precise that you don’t need to finish them with a reamer. The double-edged flutes keep these bits centered to drill straighter and smoother than other types. Carbide bits are the hardest and most wear-resistant to stay sharp at high temperatures and faster speeds. Also known as double-margin drill bits.
    Jobbers' Length—These bits have the balance of rigidity and length needed for most applications.
    Aluminum Titanium Nitride (AlTiN) Coated—The hardest and most wear-resistant coating, especially at high temperatures. These bits are best for hard and abrasive materials, such as iron and titanium.
