What is a blind hole?

A blind hole is a hole that is drilled, milled, or bored to a certain depth without breaking through the other side of the workpiece. This means that the hole does not go all the way through the material, but instead stops at a specific depth.

Blind holes are commonly used in machining and manufacturing processes to create recesses, counterbores, and other features that require a specific depth to be reached. They are often used to create a seat for a fastener, such as a screw or bolt, to be inserted into the workpiece.

When drilling a blind hole, it is important to consider the depth of the hole, as well as the diameter and angle of the hole, to ensure that it meets the requirements of the design. Special drill bits, such as step drills or center drills, may be used to create blind holes with specific dimensions.

Blind holes can be challenging to work with, as it can be difficult to accurately measure the depth of the hole and ensure that it is drilled to the correct depth. However, they are essential in many manufacturing applications and are often used in conjunction with other machining processes to create complex parts and components.
