Mitutoyo 511-428-20 Mechanical Blind Hole Bore Gauge, 0.6-1.4" Range, Dial

Description

The Mitutoyo 511-428-20 is a mechanical bore gauge in the Series 511, designed specifically for accurately measuring the inside diameter (ID) of blind holes. It comes with a dial indicator and a range of interchangeable anvils to cover a specified measurement range.

Key features

• Measurement capability: This gauge is engineered to measure the ID close to the bottom of a hole, where standard bore gauges cannot reach.
  
• Pendulum guide structure: A pendulum guide design improves the gauge's sliding action, making it easier to take consistent and accurate measurements.
  
• Two-point contact: The gauge uses a two-point contact system, which can also help detect geometric inconsistencies like ovalness and taper in a bore.
  
• Reduced heat transfer: The grip is large and hollow, a feature designed to reduce the transfer of body heat from the operator's hand and minimize its effect on the measurement's accuracy.
  
• Carbide-tipped contact points: The measuring faces are carbide-tipped for enhanced durability and wear resistance.
  
• Interchangeable anvils: The gauge includes a set of interchangeable anvils and spacers to cover the full measuring range.
  
• Optional accessories: Optional extension rods are available to measure deeper blind holes.
