Square hole found many applications in various
areas like wood, marble and metal work for different
purposes. There are many methods available to make square
hole as discussed in this work. But making a square hole
with drill operation is a different concept as in this concept
reuleaux triangle type drill cutter is used to make a square
hole. But with using this type of cutter we can produce
almost square hole not exact square hole because there left
a fillet radius on each corner of square which required
further operation. To overcome these problem different
types of drilling cutters are introduced in this work.
