Surface Broaching Tools

For those unfamiliar with modern surface broach design, its intricacies may seem complex. However, Colonial Tool standardly designs straightforward broach inserts that are easily manufactured and readily replaceable in the event of damage or wear. These inserts are assembled into a broach holder to produce the specific shape required in the finished part. We have extensive experience manufacturing tooling for a diverse range of components, including park and pawls, seat adjusters, bearing caps, connecting rods, disc brakes, plier jaws, and pump castings.

About Surface Broaching

Surface broaching is a broaching method that removes material exclusively from the external surfaces of a workpiece. Unlike other broaching techniques that might involve internal operations like boring holes or carving internal grooves, surface broaching focuses solely on shaping the exterior of the material.

Within this broad definition exists a variety of distinct tools and processes that engineers utilize to create products with varying levels of complexity. Common types of surface broaches include:

  • Slab Broaches: Used to create flat surfaces on a workpiece.
  • Slot Broaches: Designed to cut slots and can serve as an alternative to milling machines.
  • Contour Broaches: Employed to cut concave or convex curves into a workpiece.
  • Pot Broaches: Used to machine the external surface of cylindrical workpieces.
  • Straddle Broaches: Consist of a pair of slab broaches that cut both sides of a workpiece simultaneously.

Colonial Tool Group manufactures surface broaches in a wide array of profiles, with diameters ranging from 6 mm to 300 mm and a maximum length of 3,000 mm. We offer standard custom project turnaround times of 8–10 weeks, with expedited options available for rush orders—as short as two weeks. Contact us directly for a complimentary quote.

How Surface Broaching Works

Surface broaches are CNC machining tools equipped with rows of teeth in progressively larger sizes, strategically arranged to efficiently remove significant amounts of material from a workpiece, rapidly forming it into the desired shape.

Broaching tools can be installed on either horizontal or vertical machines. Once the workpiece is positioned, the tool performs the cut, moving in either a single direction or reciprocally. Stroke length and cutting speed can be adjusted as needed to achieve the precise outcome.

Often, manufacturers perform rough surface broaching on a part before heat treatment, followed by subsequent machining operations. This sequence allows for tighter dimensional tolerances, smoother surface finishes, and more precise final products. For certain materials, cutting fluid is used to maintain stable temperatures and extend tool life.

Surface Broaching Applications

Surface broaching has a wide range of industrial applications. Both ferrous and non-ferrous metals—including cold-rolled and stainless steel—as well as certain plastics are suitable for this process.

Surface broaching is often just one part of a larger manufacturing workflow. For example:

  • A fastener manufacturer may use slab broaching to cut a locating slot on a screw.
  • Automotive and military manufacturers apply surface broaching to produce complex gears and transmission components.

The specific application and required precision dictate the appropriate broaching tool and process.

Benefits of Surface Broaching

Surface broaching is a fast, cost-effective, and highly accurate machining method. Manufacturers rely on it to cut multiple dimensions in a single pass. When paired with the right tooling and equipment, it becomes one of the most economical methods of precision machining.

Key advantages include:

  • High dimensional accuracy, with tolerances up to ±0.0075 mm
  • Minimal operator training required once setup is complete
  • Reduced labor costs due to automated efficiency
