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.

Also known as screw-machine and stub-length bits, these provide maximum rigidity for drilling straighter holes than standard-length drill bits. Made of carbide-tipped steel, which has better wear resistance than high-speed steel and cobalt steel, they 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.

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.
