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.
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.
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.
Insert these bits directly into power screwdrivers, impact drivers, and other tools that accept 1/4" hex shanks.
All have a 1/4"-28 threaded shank which installs directly into the threaded spindle on a compatible drill.
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.
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.
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.
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.
Insert directly into power screwdrivers, impact drivers, and other tools that accept a 1/4" hex shank.
The built-in guide has a beveled tip that fits into countersunk holes in hardware, such as hinges and latches, to center the bit.
Attach to the shank of a drill bit to extend its reach.
Use on plastic and most metals.
For use on wood and plastic.
Drill and tap holes in a range of diameters. With a drill bit point to drive into the workpiece, these tools can drill and tap holes in a single step. Connect them directly to drills, power screwdrivers, and other tools that accept a 1/4" hex shank.
Multiple tap sizes allow tapping a range of hole diameters. Connect these taps directly to drills, power screwdrivers, and other tools that accept a 1/4" hex shank.
With a drill bit point to drive into the workpiece, these taps can drill and tap holes in a single step. A 1/4" hex shank connects them directly to tools such as drills and power screwdrivers.
These rods, also known as drill blanks, have an undersized diameter for machining your own jobbers'-length drill bits.
