Bowers SuperBore System

World reknowned for it's accuracy and ease of use, the Fowler/Bowers SuperBore System is the top of the line in production internal gauging.

Bowers Electronic Bore Gage Heads cover a wider range of hole sizes than conventional air or electronic plug gages. Bowers' system needs fewer setting rings and no sleeves.

Superbore anvils are made from Zirconia ceramic - an "advanced" ceramic which offers high strength, low coefficient of friction, better wear resistance than carbide, excellent abrasion resistance (1.5 x carbide), better corrosion resistance than carbide, coefficient expansion similar to steel, and it's non-magnetic.

The Bowers Gage Head threads onto the transducer/handle. Optional extensions in sizes 2 1/2" - 6" increase the measuring depth. The extensions can be connected to each other to further increase depth. Extensions can be used on heads above .236" diameter.
