Precision Shaft Gauge & Tip Radius Identifier
Quickly check shaft diameter and verify tip curvature with one compact, easy-to-use shop tool. The Precision Shaft Gauge & Tip Radius Identifier is designed for cue makers, repair technicians and players who want fast, consistent measurements without reaching for multiple gauges.
The lower measurement slots check shaft diameters from 11 mm to 13 mm in .25 mm increments, making it easy to identify the closest diameter during shaft work, inspections or repairs. The upper radius cutouts provide convenient Nickel, Dime and Quarter tip-radius verification, helping confirm that a cue tip has been shaped to the desired profile.
A built-in hanging hole allows the gauge to be attached to a keychain, tool board or shop hook, keeping it close at hand whenever it is needed.
