What is the Colonial vertical broaching tool?

A Colonial vertical broaching machine is a powerful and precise tool used to cut internal shapes—such as keyways, splines, hexes, and other custom profiles—into metal parts. Built by Colonial Tool Group, a well-respected name in the broaching industry, these machines are designed for high-accuracy, repeatable production in demanding manufacturing environments.

Unlike horizontal broaching machines, a vertical broaching machine operates in an up-and-down motion. This configuration is ideal for internal broaching tasks, allowing the tool to move through the workpiece in a straight, vertical path, removing material in a single pass.

What is vertical broaching?

Broaching uses a multi-toothed cutting tool, called a broach, which progressively removes material with each tooth. In vertical broaching, the broach is pulled or pushed vertically through the part, typically using hydraulic or mechanical force. This method is extremely efficient for creating complex internal shapes with precise tolerances in just seconds.

Why choose a machine shop with a Colonial vertical broaching tool?

Colonial is a recognized leader in broaching technology, known for:

• Precision engineering: Capable of holding tight tolerances on internal forms

• Rugged design: Built for durability and long production runs

• Customization: Can be adapted for a wide range of part geometries and materials

• High throughput: Ideal for high-volume production while maintaining consistency

Choosing a machine shop with vertical broaching capability—especially with a trusted brand like Colonial—offers clear advantages:

• Faster production: Internal shapes that would take much longer to machine using conventional methods can be completed in a single pass.

• Superior consistency: Broaching delivers repeatable accuracy across high volumes.

• Cost efficiency: Less tool wear, reduced labor, and faster cycle times help keep costs down.

• Expanded part capabilities: Enables production of parts that require precise internal forms—such as keyed shafts, couplings, gears, and aerospace components.

When you need internal features cut quickly and accurately, our Colonial vertical broaching machine gives us a serious advantage. Whether you’re producing thousands of parts or just a few high-precision components, we can deliver consistent, high-quality results.
