Fillet Area and Dimensions Calculators

Overview:

Fillet is a smooth, rounded transition between two intersecting surfaces. It is typically used in design and manufacturing to reduce stress concentration at sharp corners or edges. Fillets can be applied to both internal and external corners of objects, making the transition more gradual. Fillets are commonly used in engineering, architecture, and product design to improve the structural integrity of parts, enhance aesthetics, and facilitate easier manufacturing processes. A fillet is often represented as a curve with a specified radius in technical drawings.
