Square Hole Drill Bits Reviews | Top Rated

Normally, the square holes in metal sheets are made through a proper manufacturing process. What we do is first we make a round hole and chisel the whole to a square shape. This is done through the press.

This is not the process that you need to do every day but really helpful to know about metals, especially as woods are quite soft and can ‘squared’ easily.

Let us see some top products that are helpful for a square hole.
