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.

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 1/2" Diameter Reduced-Shank Drill Bit Sets
With better heat and wear resistance than high-speed steel, these cobalt steel bits can run up to 25% faster and have a longer tool life. The shank has a smaller diameter than the tip, allowing you to drill large holes with machines that have small-capacity chucks. A split point keeps the bit centered without a pilot hole. Also known as Silver and Deming bits, they have a 1/2" diameter shank.

High-Speed Steel 1/2" Diameter Reduced-Shank Drill Bit Sets
The shank has a smaller diameter than the tip, allowing you to drill large holes with machines that have small-capacity chucks. Also known as Silver and Deming, these bits have a 1/2" diameter shank.
Titanium-nitride (TiN) coated drill bits last longer and can drill at higher speeds than black-oxide drill bits.
Drill bits with flats on shank have three flat sides to prevent the bit from slipping in the drill chuck.
Drill bits with a split point keep centered without a pilot hole.

Hex-Shank Tap Sets for Drills and Screwdrivers
Multiple tap sizes allow tapping a range of hole diameters. The taps in these sets connect directly to the included screwdriver and other tools that accept a 1/4" hex shank, such as drills and power screwdrivers. They're made of high-speed steel and are for use on most metal and plastic. With a plug chamfer, they're good for start-to-finish tapping, but they'll require space at the bottom of closed-end holes for chips to accumulate.
