PLB Series

Ball Gauge

Details of series

Ball Gauge

  • The gauge is Ball shapes, so that can insert easily and can measure efficiently.
  • Standard cylindrical shape plug gauge is afraid to damage internal part of workpies by the chamfer part of plug gauge. but Ball gauge is ideal for measurement of resin, nonferrous metal parts such as Aluminum, brass and so on because adopting ball shape makes it is hard to damage the workpieces.
 

Features

  • ・ Using this gauge makes correct measurement regardless of insert angle of gauge.
  • ・ The gauge material is Tungsten Carbide, and the gauge has exceptional wear resistance.
