What is the function of the depth stop in a pillar drill?

The depth stop in a pillar drill is designed to control the maximum depth of the hole being drilled. It allows the operator to set a specific depth, ensuring consistent hole sizes across multiple workpieces. By preventing the drill bit from going too deep, the depth stop helps maintain precision and can protect the material being drilled from damage. This feature is particularly useful when working with materials that require uniform depth for fitting or assembly purposes.
