Spanners are used for all kinds of home related works. They are also a crucial part of almost all workshops, including auto shops. Most people have spanners at home and use them in the kitchen or the bathroom.
The purpose of measuring taper angle is to obtain taper angle
This is the formula for calculating a taper: Large diameter of the taper minus the small Diameter of the taper divided by the length of of the taper will give you the taper per inch. You will also need to know the included angle of the taper if you ar cutting this taper. This formula would be Tangent of the included angle divide by 2.
I'm not sure what there is to "explain" about them; they're spanners ("wrenches") that are made of an alloy containing chromium.
This means that it is the opposite of the normal direction that a taper goes. Example; If a normal taper goes to the left, a reverse taper goes to the right.
