Designing & Building Broach Tooling Since 1918
Internal broaches cut shapes on the inside surfaces of a part. Internal broaches require a starting hole or shape prior to the broaching process. Typically the starting shape is a round or rectangular machined surface. We also design broach tools that can start in a forged or cast starting hole.
Surface broach tools cut features that can be accessed from the outside perimeter of the part. These tool are mounted on a tool holder that is in-turn mounted on the broaching machine.
Keyway broaches are a subset of surface broaches. They cut internal keyway shapes, but they follow the same manufacturing process as surface broaches. Below are the size charts for standard inch and metric style keyway broaches.

What is the shape of the feature you would like cut by the broach tool? Send us a part print, existing broach tool print, or the specifications of the shape you would like to cut in your part. Let us know know how the part will be presented to the broaching operation. Will the staring hole be pre-machined, forged, or cast?
What material is your part made of? What is the hardness prior to broaching? These parameters directly affect the tool life you can expect from your broach tools. If we know these pieces of information, we can select the appropriate tool steel grade and coating combination for your application.
If you don’t have a broaching machine or don’t know the specifications, we can still quote a broach for you. We will quote the broach with an appropriate size and pull force rating to cut your part. We can also quote a machine for you.
If you already have a machine, what is the stroke and tonnage rating of the machine? Is it a vertical or horizontal style machine? If you are thinking of using a different piece of equipment, please provide a brief description.
If you’ve purchased a machine from us, we have your machine information readily available. You can include the serial number of your machine if you would like.
We work closely with tool steel mills and their distributors to control the quality and availability of the steel we use to make broach cutting tools. When quoting tools to you, we select the optimum steel grade for the most value and right tool life for your application.
Common grades are:
Our broach cutting tools are heat treated locally in Michigan. Over the decades we’ve worked with our heat treatment suppliers to establish the best quality and reliability of our tools. Our tools’ exceptional life and sharpness start with the combination of excellent tool steel and sophisticated heat treatment.
We offer a variety of coating solutions for our tools, to fit your application. We often include suggested coatings on our tool quotes, and we can provide additional coating options upon request.
