Answer 1

Explanation:

V blocks are generally made of hardened steel or cast iron and are available in a wide range of sizes.
V blocks are devices used for marking and setting up work on machines.
They are used when laying out or drilling round work.
They are found in grade A and grade B. ‘B’ grade V blocks are made from closed-grain cast iron and ‘A’ grade V blocks are made from high-quality steel.
V bock of grade A is more accurate and is found only up to 100 mm in length. V block of grade B is used for general work and is found up to 500 mm length.
