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.
High-speed steel taps and drill bits have a longer tool life than carbon steel. Uncoated high-speed steel taps and drill bits are strong enough for most jobs but don’t last as long as other high-speed steel taps and drill bits. Use them for small-scale jobs. Titanium-nitride (TiN) coated taps resist heat and wear better than uncoated taps, letting them last up to twice as long. Titanium-nitride (TiN) coated drill bits last longer and can drill at higher speeds than uncoated and oxide-coated drill bits. Black-oxide coated and black-and-gold-oxide coated taps and drill bits cut with less friction than uncoated taps and drill bits.
Cobalt steel taps and drill bits have higher strength and wear resistance than carbon steel and high-speed steel taps and drill bits.
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.
Bottoming-chamfer taps cut into the workpiece with just 1-2 chamfered threads. This short chamfer lets them thread holes closer to the bottom than other taps, but they require more torque to start threads.

Chip-Clearing Tap and Drill Bit Sets for Through-Holes
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. Because they don't need to be reversed to prevent buildup, they produce threads more efficiently than standard taps and are suitable for production work. Taps have a square shank for compatibility with tap wrenches and tap holders for drill presses and milling machines. With a plug chamfer, they have 3-5 chamfered cutting threads, so they're suitable for start-to-finish tapping. All taps and drill bits are made of high-speed steel for use on most metal and plastic.

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.

Combination Drill Bit/Pipe and Conduit Thread Taps
Drill and thread holes for pipe and conduit without switching tools. Made of uncoated high-speed steel, these tools are for use on most metal and plastic. Their right-hand spiral flutes keep chips clear by drawing them back toward the tap and out of the hole. With a square shank, they're compatible with tap wrenches and 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 of through holes.
