What's the difference between a dial depth micrometer and a digital one?

Dial models are mechanical and don't need batteries, making them reliable for workshop use, but reading them takes more skill and practice. Digital versions show measurements on an LCD screen instantly, which is faster and reduces reading errors, though they require occasional battery changes.

What measurement range do I actually need for a depth micrometer?

Most workshop jobs are covered by 0-25mm or 0-150mm models—pick based on the deepest hole or recess you regularly measure. If you work with deeper cavities or need flexibility across jobs, a longer range model saves you from buying multiple micrometers.

How do I check if a depth micrometer is accurate before buying?

Look for certification (ISO or equivalent) on the product specs, and verify the tolerance rating—±0.01mm or better is standard for quality tools. Test it against a known reference block if possible, and check that the spindle moves smoothly without grinding or sticking.

When is it worth paying more for a depth micrometer?

Invest in premium brands if you're doing precision manufacturing or quality control work where accuracy directly affects output—the difference between ±0.01mm and ±0.05mm matters. For occasional workshop use, a mid-range tool does the job fine.

What's important about the base or rod on a depth micrometer?

The base must be flat and stable so it sits properly on your workpiece, and the rod should be rigid to prevent flexing during measurement. Check that replaceable rods are available if needed, since the rod takes wear over time and may need changing.
