The parabolic spiral flutes lift chips out of the hole, reducing clogging and improving coolant flow. These bits are jobbers’ length so they have the rigidity and length required for most applications. A split point keeps the bit centered without a pilot hole.

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

These jobbers'-length bits have the rigidity and length required for most applications. Made of cobalt steel, which has better heat and wear resistance than high-speed steel, they can run up to 25% faster and have a longer tool life.

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 on these jobbers'-length bits provide increased rigidity for drilling straighter holes. Made of cobalt steel, which has better heat and wear resistance than high-speed steel, they can run up to 25% faster and have a longer tool life. A split point keeps the bit centered without a pilot hole.

For the highest accuracy and longest tool life, these solid-carbide bits 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 applications. All are jobbers’ length so they have the rigidity and length required for most applications. A four-facet point keeps the bit centered without a pilot hole.

Uncoated drill bit sets are good for general purpose drilling in most metal and plastic.

Titanium-carbonitride (TiCN) coated drill bit sets have a hard, smooth finish that resists chipping and wear. It also prevents material from accumulating on the cutting edge. They’re especially good for use on aluminum.

Aluminum-titanium-nitride (AlTiN) coated drill bit sets are the most wear and temperature resistant for the longest life and highest drilling speeds.

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. All are jobbers’ length so they have the rigidity and length required for most applications.

The shank has a smaller diameter than the tip, allowing you to drill large holes with machines that have small-capacity chucks.

The shank has a smaller diameter than the tip, allowing you to drill large holes with machines that have small-capacity chucks. Also known as Silver and Deming, these bits have a 1/2" diameter shank.

Drill bits with flats on shank have three flat sides to prevent the bit from slipping in the drill chuck.

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

The sharp point allows for gradual penetration to reduce friction and eliminate cracking and chipping when drilling in plastic.
