A wide variety of materials commonly cut during machining can also be broached using rotary broach tooling from Slater Tools. Some of these materials include soft metals such as aluminum and brass, alloy metals, stainless steel, plastics and carbon fiber.

Common materials for rotary broaching include:

• Aluminum
• Brass
• 12L14
• Alloy Steel
• Stainless Steel
• Titanium

Specifications in the Rotary Broaching Catalog will assist you in setting up speeds and feeds to cut these materials. However, these are not the only materials suitable for rotary broaching. Low carbon and leaded materials can also be broached. The higher the carbon content in the material, the more difficult it can become to broach. Tensil strength of the material plays a large role in how the material will respond to broaching. The higher the tensil strength, the more difficult it may be to rotary broach.

Although we may not recommend broaching certain materials, this does not mean they cannot be broached. Sometimes by opening up your pre-drill diameter or broaching a shallow depth, rotary broaching can be successfully accomplished. Broaching these materials may, however, reduce tool life.
