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.
Make fast bit changes—all of these bits have the same shank diameter, eliminating the need for different collets to hold each size.
Three cutting edges instead of the typical two enable these bits to drill holes with a smoother finish than other 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 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.
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.
When one end becomes worn, reverse the bit to use the other end.
These bits have short flutes and a sturdy construction which prevent snagging that deforms sheet metal and thin-wall tubing.
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.
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 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.
For general purpose use.
Carbide is harder, stronger, and more wear resistant than cobalt steel and high-speed steel for better performance on hard and abrasive materials.
For applications where the workpiece will go through several machining processes, these countersinks bevel the outer edges of the hole and provide an additional 120° chamfer to prevent damage to the center hole.
These countersinks create a surface that minimizes contact between the material and the lathe centers to prevent damage and allow for more precise machining.
Use in general purpose applications.
For excellent performance on hard and abrasive materials, these carbide countersinks are harder, stronger, and more wear resistant than cobalt steel and high-speed steel countersinks.
Use on plastic and most metals.
For use on wood and plastic.
These countersinks come attached to a high-speed steel jobbers’ bit.
Drill, countersink, and drive screws without switching three separate bits in and out of your power tool.
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.
