Starrett 55821 S167MCHZ Radius Gage Set Metric Concave Convex

The Starrett S167MCHZ is a comprehensive metric radius gage set that combines sets S167MB and S167MAH into a single 22-piece kit, complete with a Starrett 110 holder. Designed for precision inspection work, this set allows radii and fillets on concave and convex surfaces to be checked or laid out with ease, speed, and accuracy.

Key Features:

• 22 individual gages covering two measurement ranges: 0.5–7mm (in 0.5mm increments) and 8–15mm (in 1mm increments)
• Five gauging surfaces per gage to accommodate a wide variety of concave and convex radius profiles
• Satin finish stainless steel construction — rust and stain resistant for long service life
• Clearly marked radius sizes on each leaf for quick and confident identification
• Includes Starrett 110 holder with two slots allowing gages to be positioned at 30° or 45°, square in the slot or tipped to one side — ideal for confined or hard-to-reach locations
• Furnished with a protective carrying case for complete protection and easy gage selection on the job

The Starrett S167MCHZ is the metric equivalent of the popular S167CHZ fractional set, and is compatible with the full Starrett 167 series. The included 110 holder makes it easy to use individual gages independently, extending the versatility of the set to tight or awkward workpiece geometries.
