General Purpose Taps
Cut threads into most metal and plastic. These high-speed steel taps are durable enough for small-scale tapping jobs, but they're not recommended for production use. For better chip flow, choose a tap with fewer flutes.
Drive square-shank taps with a tap wrench or use them in a tap holder for drill presses and milling machines. Round-shank taps can be used with collets for machine tools, but they’re not recommended for use with a tap wrench.
Uncoated taps are strong enough for most tapping jobs but have the shortest tool life. Titanium-nitride (TiN) coated taps resist heat and wear better than uncoated taps, letting them last up to twice as long. 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.
Sets include one taper-, one plug-, and one bottoming-chamfer tap.
