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.
Access hard-to-reach spots and drill deep holes.
Use these bits for general purpose drilling in most material.
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.
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.
The sharp point allows for gradual penetration to reduce friction and eliminate cracking and chipping when drilling in plastic.
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.
Place a washer with an ID of the desired hole size over the bit and it acts as a stop to prevent the bit from drilling a larger hole.
Unlike traditional wire-installing drill bits, you do not need to strip the end of the wire when using one of these bits. After drilling, insert the wire into the bit's hollow shaft and pull through the hole.
Three drill points allow these bits to separate spot-welded panels without damaging the bottom panel.
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.
Also known as mechanics' bits, these are shorter and more rigid than jobbers’ bits but longer than short-length bits.
Designed to lift chips out of the hole, these bits reduce clogging and improve coolant flow.
Also known as reverse-flute bits, the flutes spiral in the opposite direction of other bits. Use in counterclockwise drilling applications such as removing broken screws.
Steps with progressively larger diameters let you drill a range of sizes with one bit. Also known as step drills.
Drill small holes by hand.
Use these inch size cutters with magnetic-base drills.Also known as annular cutters.
Sets include cutters, a pilot pin, and a hex key. Also known as annular cutters.
These cutters are perfectly sized for cutting holes that will be tapped later. Also known as annular cutters.
Use these metric cutters with magnetic-base drills. Also known as annular cutters.
The geometry of these cutters allows you to cut aligned holes in multiple sheets at one time. Also known as annular cutters.
For general purpose use.
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.
No need to create a starter hole—the drill point is incorporated into the countersink flutes.
Use in general purpose applications.
To remove the need for a starter hole, the drill point is incorporated into the countersink flutes.
Use on plastic and most metals.
These countersinks come attached to a high-speed steel jobbers’ bit.
Also known as step drill bits. The 82° countersink angle is compatible with the profile of flat- and oval-head inch screws.
Also called subland drill bits. The 90° countersink angle guides the tap into the hole.
Choose for general purpose applications.
For use with most metals in addition to plastic and wood.
Drill and counterbore holes with enough clearance for socket head screws without changing tools.
The same tool lets you drill and counterbore holes with enough clearance for socket head screws.
Often called step drill bits.
Also known as subland drill bits, these last longer than standard counterboring drill bits because the diameter stays the same after sharpening.
Often used with screw holes in misaligned sheets or layers of material.
No need for separate tools, these sets have counterbores in various sizes that drill and counterbore holes with enough clearance for socket head cap screws.
Keep counterbores in various sizes on hand to drill and counterbore holes with enough clearance for socket head cap screws without changing tools.
Drill and ream holes for tapered pins with the same tool. They are for use in drill presses, turret lathes, screw machines, and other machine tools.
Available in metric sizes, these tools let you drill and ream holes with the same tool. They are for use in drill presses, turret lathes, screw machines, and other machine tools.
Drill and tap a variety of hole sizes. These taps and drill bits are for use on metal and plastic.
Also known as gun taps, the taps in these sets have spiral-point flutes that push chips ahead of the tap and out of through holes.
All taps and drill bits have a hex shank for direct connection to tools such as drills and power screwdrivers.
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.
Insert these taps directly into drills, power screwdrivers, and other tools that accept a 1/4" hex shank.
Drill holes and cut threads without switching tools.
Drill and thread holes for pipe and conduit without switching tools.
Pair these arbor adapters with hollow-core cutters when using a manual drill press or milling machine. Hollow-core cutters are also known as annular cutters.
