Stainless steel construction Made from stainless steel, this protractor offers hardness, wear resistance, and longlasting durability for repeated use in demanding environments. Clear and accurate scale Engraved metric and imperial units provide precise, easytoread measurements. The scale is wearresistant, ensuring reliable readings for metalworking tasks over time. Practical folding design Folding construction allows compact storage and space savings when not in use. The sharpening end can be safely stored inside for added convenience and safety. 360degree rotating design Rotates a full 360 degrees, enabling easy measurement and marking of a wide range of angles for various applications. Applications and use scenarios Metal fabrication and machining: lay out and transfer precise angles on workpieces before cutting, drilling, or welding. Jigs, fixtures, and woodworking: set up jigs and fixtures or mark angles for woodworking tasks requiring accurate angle transfer. DIY and general repairs: check geometry, align components, and verify angles during home improvement projects.
