Double Square Rotary / Punch Broach
Although many small form applications are well suited for rotary broaching, there are times you may decide to use the broach as a punch. Some precision machine operations will be improved with this method, because the possibility of a twist or spiral in the form created when rotary broaching will be eliminated.
The greatest […]

The irony in manufacturing small parts is that smaller does not always mean simpler. In general, when you have a smaller quantity or size of something, it is easier to handle, or easier to count. However, manufacturing small metal parts is anything but simple. Even the part numbers can become quite complicated.
Manufacturing small metal […]
Rotary Broaching is a popular method for creating hexagon and square holes in metal parts. The same tooling can be used for created serration forms, such SAE, Rosan style, J500, and ANSI standard involute splines. When considering rotary broaching as an option for producing serrated forms consider these factors.
1. Tooth Height. Half of the […]
Six-Lobe Broach and Sample Parts
Creating a six-lobe form in fasteners and other driven parts is ideal due to the high amount of contact between the tool and the part. The six-lobe form has many names. The most popular version is a trademarked type know as Torx®. However, additional varieties found in the marketplace are known generically […]
When Rotary Broaching a part a pre-drill pilot hole is required. The typical pilot hole should be pre-drilled 3% lager than the “across the flats” dimension of the Rotary Broach. For example, if you are using a 1/4″ Hexagon Rotary Broach the across the flats dimension is .2525 and therefore your typical pre-drill dimension would be .260. […]
How Deep Can I Broach a Hole using a Rotary Broach Tool?
This is one of the most common questions that we receive. The standard answer is that you can broach a form 2 times the dimension across the flats of the rotary broach. For example a 3/16″ Hexagon Rotary Broach can broach a depth […]
