4PCS Stainless Steel Radius Gauge Measuring Tool, Fillet Gage Portable R0.3-1.5 R1-6.5 R7-14.5 R15-25 for Die Makers Machinists

Complete 4-Piece Set for Wide Radius Coverage: This set includes four individual radius gauges covering measuring ranges: R0.3-1.5, R1-6.5, R7-14.5, and R15-25. Whether you need to check small intricate curves or larger rounded edges, this collection provides the tools you need. Each gauge is clearly labeled with its range, allowing quick selection without confusion. Ideal for workshops, tool rooms, and quality control inspections Dual-Function Leaves for Convex and Concave Surfaces: Each gauge features two types of leaves on opposite sides: one set for checking convex (external) radii and another for concave (internal) radii. Simply select the appropriate leaf, place it against the workpiece, and visually compare the fit against light. This design eliminates the need for separate tools, saving you time and workspace while ensuring accurate radius verification Constructed from Stainless Steel for Reliable Use: These radius gauges are made from stainless steel, offering maintaining their shape over repeated use. The material withstands workshop environments, oils, and coolants without degradation. The leaves are thin enough to flex slightly for precise contact yet rigid enough to retain their calibrated curves, providing consistent measurements throughout years of service Clearly Marked Leaves for Easy Identification: Each individual leaf is engraved with its radius value, making it effortless to find the exact size you need. No more guessing or measuring twice – simply flip through the leaves, locate the marked number, and begin your inspection. This thoughtful feature speeds up workflow, especially during repetitive checks or when multiple radii need to be measured on complex parts Essential Tool for Professional Trades: This radius gauge set is widely used by machinists, tool and die makers, mold makers, quality control inspectors, and metalworkers. It helps verify the radius of shafts, corners, fillets, curved edges, and machined parts. Whether you are fabricating prototypes, repairing equipment, or performing incoming inspection, these gauges provide a quick, visual, and reliable way to confirm dimensions
