Bore Measuring Device

The Normaco Bore Measuring Device is a snap gauge for measuring bore diameters during line boring—without removing the boring bar. Designed for accuracy and efficiency, it allows machinists and field operators to take quick, repeatable measurements during on-site machining or workshop operations. It features a measuring range of 45mm to 300mm and a compact 12mm diameter body, making it compatible with various boring setups.

How It Works

1. Assemble the Device – Determine the approximate bore diameter and check the reference table to select the correct device body and extension rod. Assemble the parts accordingly.

2. Prepare the Device – Press in the spring-loaded plunger and secure it with the locking screw.

3. Position in the Bore – Insert the device through the boring bar of the line boring machine and feed it into the bore.

4. Take the Measurement – Release the screw to allow the spring-loaded measuring rod to extend and make contact with the bore surface.

5. Retrieve & Read – Tighten the screw to lock the reading, remove the device, and use a caliper to determine the bore diameter.
