Scientific Cutting Tools (SCT) is a family-owned American manufacturer based in southern California. Since 1963, we have designed and ground precision carbide cutting tools that deliver reliable accuracy, predictable tool life, and clean finishes in demanding materials and tight-tolerance work. Our product offering spans thread mills, port tools, single point tools, drills, specialty milling tools, indexable boring bars, and tool holders. All standard items are stocked and ship quickly. Custom and modified tools are built with practical lead times. Every tool reflects disciplined engineering: submicron carbide, application-driven geometries, and process control that keeps performance consistent from lot to lot. Shops rely on our manufacturing engineers for clear guidance on feeds, speeds, and setup, then see the results on the gauge and in their schedules. Across aerospace and defense, energy, medical, and high-mix job shops, manufacturers choose SCT when every minute and every thousandth matters.
