Chip-Clearing Carbide Drill Bits
The parabolic spiral flutes lift chips out of the hole, reducing clogging and improving coolant flow. For the highest accuracy and longest tool life, these solid-carbide bits are harder, stronger, and more wear resistant than high-speed steel, cobalt steel, and carbide-tipped bits. They retain a sharp, hard edge at high temperatures for the best performance on hard and abrasive material. These bits require rigid toolholding to prevent breakage and should not be used in hand-held drilling. All are jobbers’ length so they have the rigidity and length required for most applications.
Titanium-nitride (TiN) coated drill bits last longer and can drill at higher speeds than uncoated drill bits.

Hex Shank Combination Drill Bits/Taps for Drills and Screwdrivers
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. 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. All have a plug chamfer with 3-5 chamfered cutting threads, so they're suitable for start-to-finish tapping. Titanium Nitride (TiN) coated taps resist heat and wear better than uncoated taps, letting them last up to twice as long.

Combination Drill Bit/Taps
Drill holes and cut threads without switching tools. Made of high-speed steel, these taps are for use on most metal and plastic. The square shank is compatible with tap holders for drill presses and milling machines. All have a plug chamfer with 3-5 chamfered cutting threads, so they're suitable for start-to-finish tapping.
Taps with spiral flutes keep chips clear by drawing them back toward the tap and out of the hole.
Uncoated taps are strong enough for most tapping jobs but have a shorter tool life. Titanium nitride (TiN) coated taps resist heat and wear better than uncoated taps, letting them last up to twice as long.

Flex Socket Adapters
Convert your socket into a flex socket to access fasteners from an angle. Also known as universal joints.
The finish on these adapters resists corrosion. Chrome-plated adapters have a mirror-like finish and are easy to clean. Black-oxide adapters are easy to grip when dirty or wet. They need to be oiled periodically to maintain their corrosion resistance.
