Fischer Special Tooling, a custom carbide tooling company, says it creates the most precise, highest performing and cost-effective custom trepan form tools. With over 50 years of design and manufacturing experience, its engineering staff works with customers to design cutting tools for O-ring glands, VCR glands and other critical sealing features on machined components. 

The company says it creates custom form tool solutions that provide the lowest possible machining process cost per part. Its precision ground cutting tools are custom-manufactured for users’ specific facing operations. Using solid carbide, brazed carbide or high speed steel, Fischer Special Tooling says it can produce any custom shape regardless of the complexity of the tooling geometry. Its engineering staff will work with customers to design trepanning tools, face groove tools and hollow mills that offer the highest precision possible with the appropriate clearance to ensure a smooth operation.

Typical machining processes utilizing the trepan form tools include tooling to cut O-ring grooves for Parker face seal; intricate geometries on the ends of high-volume, precision-turned automotive components; end-face grooves with smooth surfaces required for metal-to-metal seals; and deep-recess hollow mill applications where off-the-shelf face grooving inserts do not perform.

Staggered flute forms, unequal index fluting, and radial and axial rake are available and can be applied to custom form end-cutting tooling, as needed. Its grinding process enables both internal and external diameter clearance, while maintaining the most repeatable form possible from flute to flute. This provides users with aggressive rates of material removal, superior surface finish and form accuracy on the final product.
