Starrett 50619 Radius Gage Set 25 Piece 1/64 to 1/2 in

Product Description

The STARRETT 50619 is a 25-piece radius gage set designed for measuring concave and convex radii on workpieces, tooling, and machined surfaces. Each leaf is stamped from stainless steel with a satin chrome finish that resists corrosion and remains legible under shop conditions. The set covers a radius range from 1/64 inch to 1/2 inch, giving technicians and machinists a broad selection of common fractional radii in a single organized kit. A holder is included to keep all 25 leaves together and protect the gaging surfaces when not in use. The full set weighs 0.313 pounds, making it easy to carry in a toolbox or service bag.

Radius gages see regular use in machine shops, fabrication facilities, and precision maintenance environments. Technicians use them to verify fillet radii on castings and forgings, check tooling wear, inspect weld preparations, and confirm that machined corners meet drawing specifications. The 25-leaf range addresses nearly all common fractional inch radii encountered in general metalworking and mechanical service work. This set is equally applicable in HVAC, plumbing, and electrical fabrication shops where sheet metal bends, tube fittings, and formed components require radius verification.

Key Features

• 25 stainless steel leaves covering 1/64 inch to 1/2 inch radius range
• Satin chrome finish reduces glare and resists corrosion in shop environments
• Includes holder (167AH and S167B) to organize and protect all leaves
• Full fractional inch coverage across 25 common radii for versatile use
• Compact and lightweight at 0.313 pounds for portable field or bench use

Compatibility

Designed as a general-purpose fractional inch radius gage set suitable for standard machine shop, fabrication, and mechanical maintenance applications where inch-unit radius measurement is required.

Installation Notes

Radius gages require no installation. Select the leaf that matches the contour of the workpiece and hold it flush against the surface in good lighting to check for gaps. Keep leaves clean and free of burrs to maintain accuracy. Store the set in the provided holder when not in use to prevent damage to the gage edges.
