These jobbers'-length bits have the rigidity and length required for most applications.
Also known as screw-machine and stub-length bits, these provide maximum rigidity for drilling straighter holes than jobbers'- and maintenance-length drill bits.
The short flutes provide increased rigidity for drilling straighter holes than standard extended-length drill bits.
Also known as mechanics' bits, these are shorter and more rigid than jobbers’ bits but longer than short‐length bits.
The short flutes on these jobbers'-length bits provide increased rigidity for drilling straighter holes.
Also known as screw-machine and stub-length bits, these provide maximum rigidity for drilling straighter holes than jobbers'-length drill bits.
The parabolic spiral flutes lift chips out of the hole, reducing clogging and improving coolant flow.
Three cutting edges instead of the typical two enable these bits to drill holes with a smoother finish than other 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.
Insert these bits directly into power screwdrivers, impact drivers, and other tools that accept 1/4" hex shanks.
In addition to resisting heat and wear better than high-speed steel drill bits, these can also run up to 25% faster and have a longer tool life. Insert them into power screwdrivers, impact drivers, and other tools that accept hex shanks.
Three sharp points allow these bits to drill accurate straight and overlapping holes, even across the grain. Also known as brad-point bits.
Carbide-tipped bits maintain their sharp edges when drilling hard material. They are for use in both 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.
Cobalt steel bits are heat resistant and maintain their sharp edges when drilling hard material. They are for use in both hand-held drilling and machine-tool applications.
Harder, stronger, and more wear resistant than high-speed steel, solid-carbide bits maintain their sharp edges longer. They require rigid toolholding to prevent breakage and should not be used in hand-held drilling applications.
Because softer metal, like aluminum, brass, and bronze, can clog a bit, the flutes on these bits lift chips out of the hole. Also known as slow-spiral drill bits.
Use for drilling in most metal.

These rods, also known as drill blanks, have an undersized diameter for machining your own jobbers'-length drill bits.
