20-25mm Three-Point Internal Micrometer for Bore Hole Measurement

20-25mm Three-Point Internal Micrometer Measuring Bore Hole

Quick Detail:

1. Three-point micrometer centering self and aligning self.

2. Measurement can be taken closer to the bottom of the blind bore and can be taken into a deep hole

with an extension rod.

3. Carbide-tipped contacts points, ratchet stop.

4. Supplied with setting rings.

5. Supplied in fitted case.

Description:

This series three-point internal micrometers offer measuring range including 6-8mm, 8-10mm, 10-12mm, 12-16mm, 16-20mm,

20-25mm, 25-30mm, 30-40mm, 40-50mm, graduation is 0.001mm within 12mm/0.5’’, graduation 0.005mm over 12mm.

Supplied with setting rings, with carbide -tipped three contact points, the errors in the measurement process can be avoided

more effectively, thus improving the accuracy of the measurement results.

The three-point micrometer features with self-centering three-point contact points for accurate bore measuring, it can center self

and aligning self, this structure allows the micrometer to be more accurate and stable when measuring blind and through holes,

the measured values are significantly more accurate than those obtained with a caliper. With three-point contact, the errors

in the measurement process can be avoided more effectively, thus improving the accuracy of the measurement results.

We also supply set with a wide measuring range.

Precautions:

1. Make sure that the measuring claw and scale of the three-point inner micrometer are clean and dust-free

so as not to affect the measurement accuracy.

2. Calibration should be performed before use to ensure that the micrometer has a correct initial reading.

3. After use, the micrometer should be cleaned and coated with a layer of anti-rust oil to prevent rust.

4. Store the micrometer in a dry, ventilated, dust-free environment to avoid moisture and heat.

5. The three-point internal micrometer is not suitable for measuring holes with rough or burr surfaces,

so as not to damage the measuring claw or affect the measurement accuracy.

Applications:

Three-point internal micrometer is mainly used to measure the holes, slotted hole, etc. It is widely used in machinery manufacturing,

automobile manufacturing, aerospace, electronic components and other industrial fields. With its high measurement accuracy,

easy to use and simple operation, it has become one of the important tools for measuring bore diameter.
