About Countersinks
Countersinks cut a cone-shaped opening to install screws and rivets flush with a surface or hold workpieces between centers on a lathe. They can also be used for chamfering and deburring.

About Counterbores

Counterboring—Enlarge the top of an existing hole to create a cylindrical-shaped opening with a flat bottom that acts as a seat for the head of a screw or wood plug.

Maintenance-Length Drill Bit Sets

Also known as mechanics’ bits, these are shorter and more rigid than jobbers' bits but longer than short-length bits. A split point keeps the bit centered without a pilot hole. Their shanks have three flat sides to prevent the bit from slipping in the drill chuck.

Chip-Clearing Drill Bit Sets

Designed to lift chips out of the hole, these bits reduce clogging and improve coolant flow. They’re jobbers’ length, so they have the rigidity and length required for most applications. A split point keeps the bit centered without a pilot hole.

Quick-Change Carbide Drill Bit Sets

Make fast bit changes—each bit has the same shank diameter, eliminating the need for different collets to hold each size. Harder than high-speed steel, cobalt steel, and carbide-tipped bits, these maintain their sharp edges longer. These bits require rigid toolholding to prevent breakage and should not be used in hand-held drilling applications. All are jobbers’ length so they have the rigidity and length required for most applications. A four-facet point keeps the bit centered without a pilot hole.

Cobalt Steel Drill-Point Countersink Sets for Lathe Centers

With more heat and abrasion resistance than high-speed steel, cobalt steel is often used on hard-to-machine materials. The countersinks in this set have a 60° countersink angles that’s compatible with the profile of centers on a lathe. They have a small drill point on the tip for drilling and countersinking holes with the same tool. The drill point creates a small gap that prevents damage to the points of live or dead centers. Turn the countersink around for a sharp cutting edge when one end dulls.

Quick-Change Combination Countersinking Drill and Screwdriver Bit Sets


Fasten differently sized screws with these sets. They save you the effort of switching three separate bits in and out of a power tool, instead letting you flip between a countersinking drill and a screwdriver bit with a single hand. You can also attach your own countersinking drills and screwdriver bits as long as they have a 1/4” hex shank.
Countersinking drills have an 82° angle, allowing inch-sized flat- and oval-head screws to sit flush with the surface.

Bit Assortments
These assortments contain general-purpose bits.
Hex shank bits (also known as insert bits) are used in hand drivers or with a bit adapter in power tools.
Hex shank bits for power tools have a groove in the shank and fit directly into power tools without an adapter. They offer more reach for recessed holes and less wobble compared to a hex shank bit used with an adapter.

Tap and Drill Bit Sets

Drill and tap a variety of hole sizes. These taps and drill bits are for use on metal and plastic.
Carbon steel taps are for thread repair and occasional tapping.
Plug-chamfer taps are a versatile choice for most tapping applications. With 3-5 chamfered cutting threads, they require moderate torque and are often used for start-to-finish tapping of through holes and closed-end holes. However, they do not start threads as easily as taper chamfers. When using them to tap closed-end holes, be sure to leave sufficient space at the bottom for chips to accumulate.

Hex-Shank Tap and Drill Bit Sets for Drills and Screwdrivers

All taps and drill bits have a hex shank for direct connection to tools such as drills and power screwdrivers. They're made of high-speed steel and are for use on most metal and plastic. Taps have a plug chamfer with 3-5 chamfered cutting threads, so they're suitable for start-to-finish tapping, but they’ll need space at the bottom of closed-end holes for chips to accumulate.

Hex-Shank Combination Drill Bit/Tap Sets for Drills and 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. They're made of high-speed steel and are for use on most metal and plastic. Their spiral flutes keep chips clear by drawing them back toward the tap and out of the hole. Recommended for use in through holes, all have a plug chamfer with 3-5 chamfered cutting threads, so they're suitable for start-to-finish tapping.

Tap, Die, and Drill Bit Sets

Cut and repair threads and drill holes in many different sizes. Tap and die wrenches are included. The dies are hex shaped for use with conventional wrenches. The taps are made of carbon steel and are recommended for thread repair and occasional tapping.
Taper-chamfer taps have 7-10 chamfered threads at the tip for cutting into the workpiece. They require less torque than other chamfer types, making them a good choice for starting threads and tapping through holes. However, a longer taper means that they cannot thread as close to the bottom of closed-end holes
Plug-chamfer taps are a versatile choice for most tapping applications. With 3-5 chamfered cutting threads, they require moderate torque and are often used for start-to-finish tapping of through holes and closed-end holes. However, they do not start threads as easily as taper chamfers. When using them to tap closed-end holes, be sure to leave sufficient space at the bottom for chips to accumulate.

Drill/Mill End Mill Sets


These multifunction tools have a 90° pointed tip that allows them to be used for drilling as well as for slotting, profiling, and chamfering cuts. Made of solid carbide, they're harder, stronger, and more wear resistant than high-speed steel for the longest life and best finish on hard material. Their extreme hardness means they are brittle, so a highly rigid setup, such as a CNC machine, is necessary to prevent the end mill from breaking. All are center cutting, allowing plunge cuts into a surface.
