Taps & Dies

Taps & dies let you cut, chase, and repair threads in metal, plastic, and even wood. Whether you’re creating new threads in a drilled hole or restoring damaged bolts and studs, these threading tools deliver clean, accurate results that help parts fit, seal, and hold torque. A quality tap and die set brings precision to shop work, field repairs, automotive projects, and plumbing jobs, saving time and money by fixing components instead of replacing them.

Taps come in several styles to match the job. Taper, plug, and bottoming taps control how quickly the tool enters and finishes a blind hole. Spiral point (gun) taps push chips forward in through-holes, while spiral flute taps pull chips out of blind holes. For pipe fittings and fluid systems, NPT and BSP pipe taps cut the tapered profiles needed for leak-tight connections. Dies are available as round, hex, and adjustable split dies to create or rethread external threads on rod, studs, and fasteners. Choose materials like high-speed steel (HSS) for durability or carbon steel for occasional use, with coatings such as black oxide or TiN to reduce friction and wear. Metric and inch standards are covered, including UNC, UNF, and fine metric pitches.

Make threading smoother with the right accessories: tap wrenches, die stocks, thread pitch gauges, tap drill size charts, and cutting fluid. Drill to the specified tap drill size, chamfer the hole, keep the tool square, and use steady pressure. Advance a half turn, back off a quarter turn to break chips, and clear swarf frequently to prevent broken taps and rough threads.

From motorcycle restorations to industrial maintenance, taps and dies improve fit, reliability, and serviceability. With the correct size, pitch, and lubrication, you’ll achieve repeatable, professional-grade threads every time. Choose clear markings and a sturdy case to keep sizes organized for faster, accurate selection.
