Cavity Tools
Precision Form Tools for Undercuts, Pockets, and Complex Internal Features
Cavity tools from Scientific Cutting Tools are engineered to reach tight spaces and create accurate internal forms where standard end mills can’t. From small undercuts to deep pockets and complex geometries, SCT cavity tools deliver the rigidity, surface finish, and repeatability you need in high-value parts.

Frequently Asked Questions
Q: Can I use one cavity tool for both roughing and finishing?
A: In many cases, yes — especially in softer materials and shorter reaches. For tight tolerances, hard materials, or very deep features, we often recommend roughing with one tool and finishing with a dedicated finishing tool.
Q: How do I reduce chatter in deep cavities?
A: Use the shortest possible tool length, optimize holder choice, reduce radial engagement, and adjust speeds and feeds based on your setup. Coated tools and proper coolant delivery can also improve stability and tool life.
Q: Can SCT design a cavity tool to match my part print?
A: Yes. SCT frequently manufactures custom cavity tools to customer prints or models, including special forms, radii, and reach requirements. Request a custom tool quote here.
Q: What coatings are available for cavity tools?
A: SCT offers multiple coating options optimized for different materials and applications. Your distributor or SCT representative can help match a coating to your material and cutting conditions.
