Specially-designed flutes keep these bits centered as they drill, resulting in straighter, rounder holes with tighter tolerances. They are titanium nitride (TiN) coated for wear and temperature resistance. Also known as double-margin drill bits.

Titanium-nitride (TiN) coated drill bits last longer and can drill at higher speeds than uncoated drill bits.

Drill bits with a split point keep centered without a pilot hole.

The short flutes provide increased rigidity for drilling straighter holes and the long length lets you access hard-to-reach spots. More wear resistant than cobalt steel and high-speed steel, these carbide-tipped bits maintain a sharper, harder edge at high temperatures for excellent performance on abrasive material, such as plastic. Because they aren’t as brittle as solid carbide bits, they can be used in less rigid setups, such as a hand-held drill. A split point keeps the bit centered without a pilot hole.

The shank has a smaller diameter than the tip, allowing you to drill large holes with machines that have small-capacity chucks. A split point keeps the bit centered without a pilot hole.
