Bore Gage

Bore Gage – Precision Tools for Accurate Internal Measurements

A Bore Gage is an essential precision tool used for measuring the internal dimensions of cylindrical objects, such as holes or bores, with high accuracy. Whether it’s a machine shop, manufacturing facility, or quality control environment, the Bore Gage plays a crucial role in ensuring parts meet the required specifications.

This tool helps detect any deviations in the internal diameter, ensuring consistency and reliability during production processes.

Key Features of Bore Gage

Precise Measurement

Designed for accurate internal diameter readings.

Adjustable Design

Adaptable for a wide range of bore sizes.

High-Resolution Readout

Clear digital or dial display for precise readings.

Durable Construction

Engineered for long-term use in industrial settings.

Applications of Bore Gages

  • Machining & Manufacturing: Measuring internal diameters of components like bushings and gears.
  • Automotive: Measuring cylinder bores, pistons, and more.
  • Aerospace: Precision checking of turbine and bearing housings.
  • Quality Control Labs: Ensuring internal diameters meet tolerances.
  • Tool Setup: Setting and verifying tools in CNC environments.

How to Use a Bore Gage

  1. Prepare the Gage: Choose the correct gage size and set to zero.
  2. Insert the Probe: Center the probe inside the bore or hole.
  3. Adjust Mechanism: Use fine adjustment to fit the probe snugly.
  4. Take Measurement: Read the internal dimension from the display.
  5. Record Reading: Log the value and compare with tolerances.

💡 Tip: Clean both the bore and probe surface before measuring for best results.
