What is a micrometer?
A micrometer is a precision measuring instrument that uses a calibrated screw thread to measure small dimensions with much finer resolution than a vernier caliper. The micrometer's spindle advances a known distance per revolution, and the thimble is graduated so the user can read the dimension directly from the scale or display. AIMS Industrial stocks Dasqua and Maxigear outside, depth and 3-point inside micrometers in digital and analogue formats across metric and imperial.
What are the main types of micrometers?
Outside micrometers measure external dimensions such as shaft diameters and stock thickness. Inside (or bore) micrometers measure internal dimensions such as cylinder bores. Depth micrometers measure the depth of slots, holes and steps. Thread micrometers measure the pitch diameter of threads. Digital micrometers add an LCD display and data output to the analogue mechanism.
What is a micrometer used for?
Micrometers are used wherever close-tolerance dimensions need to be measured — toolrooms, machine shops, quality inspection, fitting and machining. The ratchet stop on an outside micrometer ensures consistent measuring pressure between users, which is important for repeatability. Micrometers should be calibrated annually for accuracy.
Micrometer Selection — Quick Reference
Micrometers = PRECISION MEASURING from DASQUA + MAXIGEAR + MITUTOYO. Outside micrometer + inside + depth + thread + bore. Workshop + production + QA + toolroom. Match range + resolution + cal cert to work.
| Micrometer Type | Best For | Resolution |
|---|---|---|
| Outside Micrometer (0-25mm) | Most common workshop | 0.01mm |
| Outside Micrometer (25-50mm / 50-75mm / 75-100mm) | Larger workpieces | 0.01mm |
| Inside Micrometer / Bore | Internal bore measurement | 0.01mm |
| Depth Micrometer | Hole + step depth | 0.01mm |
| Digital Micrometer | Direct readout + data output | 0.001mm |
| Thread Micrometer | Pitch diameter measurement | 0.01mm |
| NATA Cal Cert | QA + audit | Per cert |
Critical: Handle CAREFULLY — drops = calibration loss. Use RATCHET STOP on outside mic (consistent pressure). Annual calibration. Brands: Mitutoyo, Dasqua, Maxigear. Companion: measuring tools, vernier calipers, digital calipers.
Micrometers — Precision Measuring from Dasqua & Maxigear
AIMS Industrial stocks precision micrometers from Dasqua and Maxigear — including outside digital micrometers, analogue outside micrometers, depth micrometers and 3-point inside micrometer sets in both metric and imperial. Whether you're working in a toolroom, quality lab or on the shopfloor, these instruments deliver the accuracy and repeatability needed for critical-tolerance measurement.
Micrometer Types We Stock
- Dasqua Outside Digital Micrometer — Metric: Digital readout for fast, accurate OD measurement with clear LCD display. Dasqua digital micrometers are built to ISO standards and are favoured for high-volume inspection work.
- Dasqua Outside Micrometer — Metric & Imperial: Analogue outside micrometers for standard OD measurement. Available in metric and imperial graduation — suitable for workshops where digital instruments aren't required.
- Dasqua Depth Micrometer — Metric & Imperial: Precision depth measurement for slots, shoulders and blind holes in both metric and imperial. Dasqua depth micrometers feature interchangeable rods for extended range.
- Dasqua 3-Point Inside Micrometer Set: Three-point inside micrometer set for accurate bore and ID measurement — eliminates the rocking error associated with two-point gauges. Ideal for cylinder bores and sleeve IDs.
- Maxigear Digital Depth Gauge: Maxigear digital depth gauge for step and depth measurement with large digital display. A versatile tool for both bench measurement and production floor use.
Choosing the Right Micrometer
- Digital vs Analogue: Dasqua digital micrometers speed up measurement and reduce reading errors — ideal for repetitive tasks. Analogue models are preferred where calibration records require a non-electronic instrument or for lower-volume use.
- Metric vs Imperial: AIMS stocks both metric and imperial variants across the Dasqua range. If you work to both standards, confirm your measurement range and graduation before ordering.
- Outside vs Depth vs Inside: Outside micrometers measure OD; depth micrometers measure depths and steps; inside micrometers (3-point) measure bores. Most workshops need at least outside and depth variants as a baseline.
- Measurement Range: Dasqua outside micrometers are available in standard ranges — verify your required measurement range against the product specifications listed on each item page.
