Drilling Jigserefore, tool designers and production engineers give utmost importance to proper location of the holes in the workpiece as well as on the machine, with the required tolerances and surface finish. It may be seen that the location and size of the hole are two important facets of mass production of components.

Other Types of Fixtureser types of the fixtures particularly turning fixtures need the same amount of attention in the design and construction. In the case of broaching fixtures, the same does not need any specific clamping devices as the broaching action itself will provide the requisite clamping force on to the component.
