Inch hand taps are cutting tools used to produce internal threads to inch standards (UNC/UNF/BSW) by removing material inside a pre-drilled hole. They are driven with a tap wrench to keep alignment and control cutting torque.
Available as 2- or 3-piece sets (taper/second/plug or bottoming) for progressive cutting and lower torque, in multiple diameters, pitches and lengths. Options include HSS and HSS-E, straight-flute designs, from Baer, Yg & Hepyc.
Well suited for maintenance, machine shops and fabrication where inch fastener compatibility is required. Choose based on material, pitch and the correct tap drill size.
Tap taps are precision cutting tools used to create an internal thread in a hole (e.g. in nuts or holes in metal). This process is called tapping and requires the use of a special tap wrench or machine (drill/CNC).
