Tap threads for left-hand threaded fasteners. Made of uncoated high-speed steel, these taps are durable enough for small-scale tapping jobs, but they're not recommended for production use. All have a square shank that's compatible with tap wrenches and tap holders for drill presses and milling machines.

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.

Sets include one taper-, one plug-, and one bottoming-chamfer tap.

Insert these taps directly into 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. All have a plug chamfer with 3-5 chamfered cutting threads, so they're suitable for start-to-finish tapping. When using them to tap closed-end holes, be sure to leave sufficient space at the bottom for chips to accumulate.

Keep chips clear while tapping. Also known as gun taps, these 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. They're made of high-speed steel for use on most metal and plastic. 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.

Use uncoated taps for short production runs. Titanium-nitride (TiN) coated taps resist heat and wear better than uncoated taps, letting them last up to twice as long. Titanium-carbonitride (TiCN) coated taps have up to three times the tool life of uncoated taps. Their hard, smooth finish offers superior resistance to chipping, wear, and heat.

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.

Uncoated taps are strong enough for most tapping jobs but have the shortest tool life.

With a taper chamfer and bottoming chamfer at opposite ends, these taps start threads easily and are good for threading close to the bottom of closed-end holes. The taper chamfer has 7-10 chamfered cutting threads to drive into the workpiece and start threads with less torque than other chamfer types. The bottoming chamfer has 1-2 chamfered cutting threads to create full threads near the bottom of closed-end holes. To tap threads, turn the tap with an open-end wrench or drive it at either end using an L-key or ratchet wrench. All are made of high-speed steel and are for use on most metal and plastic.

These taps are made of high-speed steel for higher strength and wear resistance than standard taps. Their flutes are designed to keep chips clear, so they don't need to be reversed to prevent buildup. With a square shank, they're compatible with tap wrenches and tap holders for drill presses and milling machines. Taps with plug chamfers have 3-5 chamfered cutting threads. Taps with bottoming chamfers have 1-2 threads.

Taps for through-hole threading have spiral-point flutes, which push chips ahead of the tap and out of through holes. They're also known as gun taps.

Taps for closed-end hole threading have right-hand spiral flutes. They draw chips back toward the tap while cutting threads to prevent chip accumulation in closed-end holes.

Coated with chromium carbide or titanium carbonitride (TiCN), these cobalt steel taps cut smoothly through soft material to produce accurate threads. Their square shank is compatible with tap wrenches and tap holders for drill presses and milling machines.

Taps for through-hole threading have left-hand spiral flutes to push chips ahead of the tap and out of through holes. All have a plug chamfer with 3-5 chamfered cutting threads, so they start threads with moderate torque and are good for start-to-finish tapping.

To tap nickel and other hard material, these cobalt steel taps have high cutting strength. Their spiral flutes keep chips clear, so they don't need to be reversed to prevent buildup. 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.

Taps for through-hole threading push chips ahead of the tap and out of through holes.

Taps for closed-end hole threading draw chips back toward the tap while cutting threads, preventing chip accumulation in closed-end holes.

Attach these tools to a socket wrench to restore rusted and damaged spark plug threads in two common sizes.

These taps are for use on most metal and plastic. They have a square shank that's compatible with tap wrenches and tap holders for drill presses and milling machines.

Uncoated carbon steel taps are for thread repair and occasional tapping. Use uncoated high-speed steel taps for small-scale tapping jobs. Titanium-nitride (TiN) coated high-speed steel taps resist heat and wear better than uncoated taps, letting them last up to twice as long.
