The Sigma Kera-Flex 38F3 is a high-performance attachment designed to transform your Sigma Kera-Cut guide rail into a precision electric saw. Engineered for professionals handling dense porcelain slabs and large-format tiles, this system replaces manual scoring with a controlled, motorized cut. Whether you need to make plunge cuts for outlets, L-cuts for corners, or full-length passes on tiles up to 25mm thick, the Kera-Flex provides the stability and depth control required for a perfect finish. Compatible with most standard 4.5″ to 5″ angle grinders, it features a dual ball-bearing carriage for a smooth, “chatter-free” glide across the rail.

Universal Grinder Attachment: Built with a standard 5/8″-11 UNC spindle thread (U.S. Standard) to accommodate any angle grinder up to 1400W.
Adjustable Depth Stop: Intuitive depth control allows you to set the blade height precisely, protecting your workbench and ensuring consistent cuts.
Dual-Wheel Stabilization: Features a new stabilization system with wear-resistant coated wheels and double ball bearings to minimize vibration and tracking errors.
Dry or Wet Ready: Integrated dust extraction port for a clean workspace, or pair it with the optional “Waterkit” for wet-cutting high-density materials.
Disc Visibility Indicator: Includes a clear positioning label that shows exactly where the blade will overhang, allowing for predictable starts and stops.
High-Capacity Cutting: Capable of handling ceramic and porcelain materials from 5mm up to 25mm (1 inch) in thickness.

Mastering Large Format: Setting Up the Sigma Kera-Flex 38F3

Target Audience: Tile contractors, stone fabricators, and specialized installers working with 12mm and 20mm porcelain slabs.

Value Proposition: “The Sigma Kera-Flex bridges the gap between manual rail cutters and expensive bridge saws. It offers the portability of a rail system with the raw power of an electric saw, making it the most cost-effective way to achieve factory-edge quality on thick, large-format materials.”

Pro Tip: For the best results on ultra-dense porcelain, use the Kera-Flex in conjunction with the Sigma Waterkit to cool the blade and eliminate dust entirely.
