Key Features:

• Metric radius range: 7.5mm to 15mm
• 32 precision-ground steel leaves for comprehensive radius coverage
• Leaves measure both concave and convex radii
• Hardened and ground blades for long-lasting accuracy and durability
• Compact fan-style design for easy one-hand operation in the field or at the bench
• Clearly etched radius markings on each individual leaf for quick identification
• Sturdy protective case keeps leaves organized and protected when not in use
• Manufactured by Starrett, a trusted name in precision measurement tools since 1880

The 178MB is the metric companion to Starrett's popular inch-series radius gage sets and is an essential tool for any machine shop, inspection department, or toolroom working to metric standards. The fan-style leaf design allows rapid selection of the correct radius blade, and the hardened steel construction ensures consistent, repeatable measurements over the life of the tool.
