Info Glatt-GUT-LD Smooth GO plug gage • The smooth GO plug gage checks the minimum drilled hole dimension including certain form deviations, e.g. circularity and cylindricity. • It must be possible to push the smooth GO plug gage by hand into the full length of the drilled hole without the use of particular force. • To achieve higher wear resistance, EMUGE recommends using the smooth GO plug gage in the hard-chrome-plated or carbide version. • Dimensions of the smooth GO plug gage acc. DIN 2246 and DIN 2248. Glatt-AUS-LD Smooth NO-GO plug gage • The smooth NO-GO plug gage checks whether the drilled hole diameter has exceeded the prescribed maximum size. • It must not be possible to insert the smooth NO-GO plug gage into the drilled hole without the use of particular force. • The smooth NO-GO plug gage is marked with a red coloured ring. • Dimensions of the smooth NO-GO plug gage acc. DIN 2247 and DIN 2249. 6.5 Smooth plug gages for drilled holes acc. DIN EN ISO 1938-1 The smooth GO plug gage and the smooth NO-GO plug gage are used for gaging fitting drilled holes. GO and NO-GO plug gages are mounted on one handle for drilled hole diameters up to 65 mm and are designated as smooth GO/NO-GO plug gages.
