Tap

 

(Screw Tap), a tool for cutting a screw thread in a previously drilled hole. A tap is a cylindrical spindle with cutting edges at one end. The other end, or shank, is designed to be fastened in a chuck or held in a tap wrench while being turned.

The main types of taps are manual taps; inside taps, for cutting a complete thread in through holes in one traverse; machine taps, for cutting threads mainly in blind holes on drilling machines, automatic machines, and special assembly-line units; machine-tool taps, for making threads in through holes on nut-tapping machines; grooveless taps, for cutting threads in through holes in one traverse; automatic taps, for cutting threads in nuts on automatic nut-tapping machines; and die and master taps, for cutting threads and thread gauges and removing the burrs in the threaded holes of circular dies. The materials used to make taps are alloy tool steel and high-speed steel.
