Introductions:
The bench work and fitting play a important role in every engineering workshop to complete and finish the job to desired accuracy.
The work carried out by hand at the bench is called bench work. Whereas fitting is the assembling of parts together by filling, chipping, sawing, scraping and tapping etc. Fitting shop tools:
