Why do drill bits sometimes break when drilling using a pedestal drilling machine?

Drill bits can break when using a pedestal drilling machine due to excessive feed pressure, which can cause the bit to bind or overload. Inadequate cooling or lubrication can lead to overheating, weakening the bit material. Additionally, using the wrong type of bit for the material being drilled or encountering hard spots can also contribute to breakage. Proper technique, suitable bit selection, and maintaining adequate cooling are essential to prevent this issue.
