Product Information

Full details

This Draper Expert Quality Metric External Micrometer (0-25mm) is designed for precision machinists and engineers requiring accurate external measurements. Its key benefit is the high level of accuracy (0.01mm graduations) and durable construction. A potential caveat is its specific measurement range, making it ideal for smaller components only.

Extended Product Information

FAQs

What is the measurement accuracy of this micrometer?

This micrometer has graduations of 0.01mm, providing high precision for accurate measurements within its range.

Can this micrometer be used for imperial measurements?

No, this is a metric external micrometer and is calibrated for use with metric measurements only.

How do I ensure consistent measurements?

Utilize the ratchet stop to apply consistent measuring pressure. Ensure the anvils are clean and the part being measured is stable.

What material are the anvils made of?

The anvils are carbide-tipped for enhanced durability and wear resistance.

What is the maximum measurement this micrometer can take?

The measurement range for this micrometer is 0-25mm.

How should I clean the micrometer?

Use a soft, dry cloth to wipe down the micrometer. Ensure measuring surfaces are clean before and after use.

Is recalibration necessary, and how often?

Recalibration is recommended periodically or if the micrometer has been dropped or shows a consistent zero error. Frequency depends on usage and workshop conditions.

Troubleshooting

Micrometer does not return to zero

Clean the measuring surfaces. If the error persists, it may require recalibration. Ensure the lock nut is not overtightened, which can affect spindle movement.

Sticking or stiff thimble movement

Check for dirt or debris on the thimble and sleeve. Lightly lubricate the threads if necessary, following manufacturer recommendations. Ensure the frame is not warped or damaged.

Inconsistent readings

Ensure consistent measuring pressure by using the ratchet stop correctly. Verify that the anvils are clean and free from burrs. Check for any play in the spindle.

Pros and Cons

Pros

  • High precision with 0.01mm graduations.
  • Durable construction with carbide-tipped anvils.
  • Includes a lock and ratchet stop for consistent measurements.
  • Comes with a protective storage case.

Cons

  • Limited measurement range (0-25mm) restricts its use to smaller components.
  • Requires careful handling and calibration for continued accuracy.
  • Not suitable for internal or depth measurements.

Setup, Compatibility & Care

Setup: The micrometer is ready for use upon removal from its case. Ensure the thimble and sleeve are clean before first use.

Compatibility: This micrometer is designed for metric measurements and is compatible with standard workshop environments. It is not designed for use with imperial measurement systems.

Care:

  1. Always store the micrometer in its protective plastic case when not in use.
  2. Keep the measuring surfaces (anvils and spindle face) clean and free from debris or oil.
  3. Avoid dropping or subjecting the micrometer to impacts, as this can affect calibration.
  4. Periodically check for zero error by closing the jaws completely. Adjustments, if needed, should be performed by a qualified technician or following manufacturer guidelines.
  5. Use a soft, dry cloth for cleaning. Avoid harsh solvents.
