What is Blind Broaching?
Blind broaching refers to the machining of a piece part in which the broaching tool is unable to, because of the design of the part, pass completely through or completely past the part. The broach therefore must cut into a ‘blind’ cavity of some sort.
At V W Broaching Service, we perform all types of blind broaching operations, from the most simple ‘punching’ of a square shape into a round hole, to more complex forms involving multiple passes and many successive tools. An example of a blind broaching operation would be the cutting of an internal hexagon or spline into a headless setscrew. Designing the tooling for, and executing the process of blind broaching is very much an art reserved for the most experienced of craftsmen.
