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.
Specially-designed flutes keep these bits centered as they drill, resulting in straighter, rounder holes with tighter tolerances. Also known as double-margin drill 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.
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.
Drill long, straight holes with these bits. Channels in the bit allows coolant to flow through the tool for more efficient chip evacuation. Also known as gun drills.
Use these bits for general purpose drilling in most material.
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.
The SDS-Plus shank has two deep slots and two shallow slots for use with SDS-Plus-drive rotary hammers.
These bits have a round or hex shank that fits into the three-jaw chuck on a hammer drill.
A more controlled chip removal reduces heat buildup. Use these bits on brittle material such as block and brick.
Three sharp points allow these bits to drill accurate straight and overlapping holes, even across the grain. Also known as brad-point 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.
Harder, stronger, and more wear resistant than carbide-tipped 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.
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 cobalt 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.
These hollow bits are diamond-tipped for long life and fast cutting speeds. Only for use in drill presses.
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.
Attach to the shank of a drill bit to extend its reach.
Use on plastic and most metals.
For use on wood and plastic.
These rods, also known as drill blanks, have an undersized diameter for machining your own jobbers'-length drill bits.
