Construction & Design

The SPC Performance 4.0-inch Flared Hole Die features a robust construction utilizing high-grade hardened tool steel, ensuring resistance to wear and deformation during repeated use. Its design incorporates a flared opening that allows for precise expansion of holes up to 0.090 inches in chromoly or 0.125 inches in mild steel, providing reinforcement and increased panel strength. The die's geometry is optimized through finite element analysis, resulting in a tool that delivers consistent, smooth flares with minimal distortion or deformation of the surrounding material.

The compact, lightweight profile of the die makes it easy to handle and integrate into your fabrication setup. Its precision-machined surfaces ensure a tight fit and reliable performance, while the hardened steel construction guarantees long service life even under rigorous use. Whether used in a dedicated sheet metal brake or with specialized flaring tools, this die is designed to deliver professional-grade results every time.

Installation & Fitment

Using the SPC Performance 4.0-inch Flared Hole Die is straightforward and requires no special tools beyond your standard sheet metal fabrication setup. Simply align the die with the hole to be flared, and apply appropriate force using a hydraulic press, hand tool, or flaring machine. The die's design ensures a secure fit and consistent results with minimal effort. No cutting, drilling, or additional modifications are necessary to utilize this die effectively, making it an excellent choice for both professional shops and DIY fabricators.
