The Serdi Profile L is a high-performance, CNC-controlled single-point valve-seat machining center designed for precision cylinder-head work across automotive, diesel, racing, motorcycle, marine, and industrial applications. Using Serdi’s industry-leading centering technology combined with modern CNC interpolation, the Profile L produces extremely accurate, fully programmable valve-seat profiles — including multi-angle, full radius, blended forms, and motorsport-grade custom geometries.
Built for engine builders who demand repeatability, accuracy, and flexibility in seat-shape design, the Profile L eliminates the limitations of traditional fixed-angle tooling. The machine’s rigid structure, servo-driven spindle, precision ball screws, and digital depth control allow the operator to cut exact seat geometries with tight tolerances and exceptional concentricity.
Whether for OEM-style seat restoration, performance upgrades, or extreme racing applications, the Serdi Profile L delivers world-class seat quality with CNC repeatability.

Decades before today’s engine shops trusted our equipment, Tony was already deep in the craft — rebuilding motors, machining blocks, and pushing for better precision.
A local newspaper once featured him as a standout young machinist, noting his drive, attention to detail, and obsession with doing things the right way. That same passion would eventually shape our company’s values.
Today, that commitment lives on in every machine we sell, every customer we support, and every shop we help succeed.
