M14 Taps | McMaster-Carr

Cobalt Steel—These taps resist higher temperatures and and last twice as long as high-speed steel taps. They thread hard materials such as iron and hardened steel without damaging their cutting edges.

Carbon Steel—The economical choice for occasional hand tapping. These work on most metals and plastic but will dull more quickly than other taps.

Uncoated—The economical choice, these won't last as long as coated taps.

Titanium Nitride (TiN) Coated—Run at higher speeds and last twice as long as uncoated taps.

Taper Chamfer—Good for both starting holes and threading through holes. These taps have the longest taper to gradually engage with the material, reducing the force needed to turn them. They can't reach the bottom of blind holes, however, so you will likely need to finish with a bottoming-chamfer tap.

Plug Chamfer—Our go-to chamfer type, these thread both through holes and blind holes. The tapered section is shorter than a taper chamfer and longer than bottoming chamfer. As a result, they're easier to turn than bottoming taps but require more force than taper taps.

Bottoming Chamfer—Cut all the way to the bottom of blind holes with taps that have the shortest taper. Since these require the most force to turn, they’re often used to finish holes started by taper- or plug-chamfer taps.

Number of Flutes—Taps with fewer flutes have more space to capture chips, so you won’t have to clear them as often. However, they can be more difficult to keep straight in the hole.

Taps Sold as Sets—Include one tap of each chamfer type.

Tap and Die Sets

Use a single set for many sizes of internal and external threads. The taps and dies are for use on most metal and plastic.

Carbon Steel—Carbon steel taps are for thread repair and occasional tapping.

Plug Chamfer—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-chamfer taps. When using them to tap closed-end holes, be sure to leave sufficient space at the bottom for chips to accumulate.

Taper Chamfer—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.

Hex—Hex-shaped dies are for thread repair and can be used with conventional wrenches.

Chip-Clearing Taps

Spiral-Point Flute for Through Holes

Remove long, stringy chips to produce cleaner threads than standard taps. The flute design prevents buildup to protect the quality of the threads and avoid damage to the tap. Since you don’t need to reverse these taps to extract chips, they also create threads faster.

High-Speed Steel—The most versatile taps resist heat and wear to stay sharp. They’re good for most metals and plastic.

Uncoated—The economical choice, these won't last as long as coated taps.

Titanium Nitride (TiN) Coated—Run at higher speeds and last twice as long as uncoated taps.

Titanium Carbon Nitride (TiCN) Coated—Resist heat, chipping, and wear for three times the life of uncoated taps.

Spiral-Point Flute for Through Holes—Push chips ahead of the tap and out of through holes. Also known as gun taps.

Plug Chamfer—Our go-to chamfer type. With a longer taper than a bottoming chamfer, they are easier to turn but won't thread as close the bottom of a hole.

Chip-Clearing Taps for Steel and Stainless Steel

Spiral-Point Flute for Through Holes

Made of a high-vanadium alloy, these taps are harder and more wear-resistant than other high-speed steel taps. The flute design prevents buildup to protect the quality of the threads and avoid damage to the tap. Since you don’t need to reverse these taps to extract chips, they also create threads faster.

High-Speed Steel—The most versatile taps resist heat and wear to stay sharp. They’re good for most metals and plastic.

Black Oxide—The dark finish increases wear resistance and reduces friction to improve chip flow, so these taps can last 50% longer than uncoated taps.

Spiral-Point Flute for Through Holes—Push chips ahead of the tap and out of through holes. Also known as gun taps.

Plug Chamfer—Our go-to chamfer type. With a longer taper than a bottoming chamfer, they are easier to turn but won't thread as close the bottom of a hole.

Trapezoidal Thread Taps

The metric version of Acme thread taps. These cut the broad threads found on lead screw nuts, linear actuators, vises, and other moving components. They have two sets of chamfered threads: the first for cutting a rough profile and the second for finishing it. They’re only for through holes since the two different chamfers can damage the workpiece if you reverse the tap. Once done threading, release the tap from the holder and remove it from the other side of the hole. Also known as tandem taps.

High-Speed Steel—These taps resist heat and wear to stay sharp.

Left-Hand Thread Tap Sets

Three chamfer types in one set create a snug fit with left-hand fasteners that secure counter-clockwise rotating parts. Left-hand threads keep components such as flywheels and propellers from loosening and spinning off. These taps have straight flutes that are good for most jobs.

Chip-Clearing Taps for Nickel

Spiral Flute for Through Holes

Avoid heat buildup that can deform material and prematurely wear taps when threading nickel alloys. The body on these taps narrows closer to the flutes for better coolant flow and less contact with the workpiece. Spiral flutes prevent stuck chips that can slow you down and decrease the quality of the threads.

Cobalt Steel—Tough and wear resistant, cobalt taps last twice as long as high-speed steel. They also can run at higher temperatures without damage to their cutting edges.

Black Oxide—The dark finish increases wear resistance and reduces friction to improve chip flow, so these taps can last 50% longer than uncoated taps.

Spiral Flute for Through Holes—Left-hand flutes push chips ahead of the tap and out of through holes.

Plug Chamfer—Our go-to chamfer type. With a longer taper than a bottoming chamfer, they are easier to turn but won't thread as close the bottom of a hole.

Quick-Change Hex Shank Drill Taps for Drills and Screwdrivers

Save time when you need to change drill taps frequently. The grooved shank snaps directly into drills, power screwdrivers, and other tools that accept a 1/4" hex shank. However, they’re not rated for impact drivers. With a drill bit point to drive into the workpiece, these taps can drill and tap holes in a single step. 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 High-Speed Steel—Uncoated taps are strong enough for most tapping jobs but have the shortest tool life.

2-in-1 Taps


	End View

Start threading a hole with one end of these taps and finish it with the other. The taper-chamfer end gradually engages with the material, reducing the force needed to turn the tool. Flip to the bottoming-chamfer end, which has a shorter tapered section, to thread all the way to bottom of holes. No special holder needed—turn these taps with an open-end wrench, or drive from either end using an L-key or ratchet wrench. Taps have straight flutes that are good for most jobs.
