Taps And Dies
Taps and dies are tools used to create screw threads, which is called threading. Many are cutting tools; others are forming tools. A tap is used to cut or form the female portion of the mating pair (e.g. a nut). A die is used to cut or form the male portion of the mating pair (e.g. a bolt). The process of cutting or forming threads using a tap is called ''tapping'', whereas the process using a die is called ''threading''. Both tools can be used to clean up a thread, which is called ''chasing''. However, using an ordinary tap or die to clean threads generally removes some material, which results in looser, weaker threads. Because of this, machinists generally clean threads with special taps and dies—called ''chasers''—made for that purpose. Chasers are made of softer materials and don't cut new threads. However they still fit tighter than actual fasteners, and are fluted like regular taps and dies so debris can escape. Car mechanics, for example, use chasers on spark plug thr ...

Tool And Die Maker
Tool and die makers are highly skilled crafters working in the manufacturing, manufacturing industries. Variations on the name include tool maker, toolmaker, die maker, diemaker, Moldmaker, mold maker, moldmaker or tool jig and die-maker depending on which area of concentration or industry an individual works in. Tool and die makers work primarily in toolroom environments—sometimes literally in one room but more often in an environment with flexible, semipermeable boundaries from production work. They are skilled artisans (craft production, craftspeople) who typically learn their trade through a combination of academic coursework and with substantial period of on-the-job training that is functionally an apprenticeship. They make Jig (tool), jigs, Fixture (tool), fixtures, die (manufacturing), dies, molding (process), molds, machine tools, cutting tool (machining), cutting tools, gauge (instrument), gauges, and other tools used in manufacturing processes.
