The parabolic spiral flutes lift chips out of the hole, reducing clogging and improving coolant flow. With better heat and wear resistance than high-speed steel, these cobalt steel bits can run up to 25% faster and have a longer tool life. All 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.

Holes in these bits allow coolant to be run through the tool for more efficient chip evacuation. Use them in CNC machines with coolant-through technology. 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. A titanium aluminum nitride (TiAlN) coating gives them additional wear and temperature resistance. The four-facet point keeps the bit centered without a pilot hole. These bits require rigid toolholding to prevent breakage and should not be used in hand-held drilling applications.

Jobbers'-length drill bits have the rigidity and length required for most applications.

Maintenance-length drill bits are shorter and more rigid than jobbers'-length bits but longer than short-length bits. They hold up better than jobbers' bits when drilling in hard metal. Also known as mechanics' 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.

Insert these bits directly into power screwdrivers, impact drivers, and other tools that accept 1/4" hex shanks. 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 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.

The straight flutes and notched point withstand the heavy pressure necessary to penetrate hard steel. These carbide-tipped bits maintain their sharp edges when drilling abrasive material. Because they aren’t as brittle as solid carbide bits, they can be used in less rigid setups, such as a hand-held drill. They are jobbers' length and have the rigidity and length required for most hand-held drilling and machine tool applications.

The sharp point allows for gradual penetration to reduce friction and eliminate cracking and chipping when drilling in plastic. These bits are jobbers' length and have the rigidity and length required for most applications.
