Drill Bits for Precise Holes
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.

Carbide Drill Bits for Precise Holes
Specially-designed flutes keep these bits centered as they drill, resulting in straighter, rounder holes with tighter tolerances. Made of solid carbide for the highest accuracy and longest tool life, they are harder, stronger, and more wear resistant than high-speed steel, cobalt steel, and carbide-tipped bits. They retain a sharp, hard edge at high temperatures for the best performance on hard and abrasive material. These bits require rigid toolholding to prevent breakage and should not be used in hand-held drilling. All are jobbers’ length so they have the rigidity and length required for most applications. An aluminum titanium nitride (AlTiN) coating gives them additional wear and temperature resistance. Also known as double-margin drill bits.

Short-Flute Extended-Length Carbide-Tipped Drill Bits
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.

Drill Bits for Wood Screws
These bits are cut to match a wood screw’s thread and diameter, resulting in a perfect fit for a screw. They produce clean edges when cutting soft and hard wood.

Cobalt Steel Left-Hand Drill Bits
With better heat and wear resistance than high-speed steel, cobalt steel bits can run up to 25% faster and have a longer tool life. Also known as reverse-flute bits, the flutes spiral in the opposite direction of other bits. Use in counterclockwise drilling applications such as removing broken screws. These bits are maintenance length, also known as mechanics’ length. They are shorter and more rigid than jobbers’ bits but longer than short-length bits. The split point keeps the bit centered without a pilot hole.
