3 Points Inside Micrometer 10 12 Mm 0.004 Mm Acc. 0.001 Mm Grad.

A Precision Measuring Instrument Designed To Measure The Internal Diameter Of Bores, Cylinders, And Other Similar
Features With High Accuracy. This Tool Is Commonly Used In Engineering, Machining, And Quality Control To Ensure
That Internal Dimensions Meet Specified Tolerances. Unlike Traditional Inside Micrometers, The Three Point Contact
System Allows For More Stable And Reliable Measurements, Particularly In Larger Bores.

• 6 12mm Graduation: 0.001mm
  
  Steel Measuring Faces
  
  12 300mm Graduation: 0.005mm
  
  Carbide Measuring Faces


• Ratchet Stop


• Extension Rod Are Included


• Setting Rings Are Included (Range < 100mm)

How It Works:

• Three Point Contact: The Micrometer Has Three Measuring
  Points That Evenly Distribute Pressure On The Inner Surface Of The Hole, Ensuring
  Accurate And Repeatable Measurements.


• Digital Display: The Measured Diameter Is Displayed Digitally,
  Eliminating The Need For Manual Reading And Reducing The Possibility Of Errors.


• Extension Rods: These Can Be Used To Measure Deeper Holes.

Applications

• Machining And Metalworking: Used To Measure The
  Internal Diameters Of Bores And Holes In Metal Components, Ensuring That
  They Meet The Required Specifications.


• Quality Control: Essential In Inspection Processes To
  Verify The Accuracy Of Internal Dimensions In Manufactured Parts.


• Engineering: Applied In Various Engineering Tasks Where
  Precise Internal Measurements Are Critical, Such As In The Design And
  Fabrication Of Mechanical Parts.


• Automotive And Aerospace Industries: Used For Measuring
  The Internal Diameters Of Engine Cylinders, Bearing Races, And Other
  Critical Components That Require Precise Tolerances.

Advantages Of Three Point Micrometers:

• Improved Accuracy: Ensures Precise Centering And
  Measurement Compared To Two Point Micrometers.


• Reduced Measurement Error: Minimizes The Impact Of
  Bore Irregularities.


• Suitable For Various Shapes: Can Be Used For Both
  Cylindrical And Irregular Bores.
