Mitutoyo 293-669-20 QuickMike Micrometer 75-105mm | KSA
Product Summary
The Mitutoyo 293-669-20 QuickMike micrometer measures large metric components from 75 to 105 mm with 0.001 mm resolution and ±3 µm instrumental accuracy. Its rapid spindle advances 10 mm per thimble rotation, allowing the full measuring range to be covered in approximately three turns. The ABSOLUTE linear scale retains the origin after power-off, while IP65 protection helps protect the instrument against dust and coolant. A 75 mm standard bar is included for origin setting.
Product Description
The Mitutoyo 293-669-20 QuickMike micrometer is designed for outside measurement of larger metric components in the 75–105 mm range. It is suited to machine shops, maintenance facilities and inspection departments where large shafts, housings and turned components need to be checked quickly and consistently.
The QuickMike mechanism provides a rapid 10 mm spindle feed per thimble rotation, allowing the measuring faces to travel across the 30 mm range in approximately three turns. This reduces the amount of manual winding required when measuring different component sizes.
The micrometer provides 0.001 mm resolution and ±3 µm instrumental accuracy. Its measuring faces are carbide-tipped with a micro-lap finish, while the 6.35 mm diameter non-rotating spindle helps maintain controlled contact with finished surfaces.
A ratchet friction thimble provides a specified measuring force of 5–12 N, supporting consistent measurement technique. The instrument also provides 0.3 µm flatness and 3 µm parallelism.
The ABSOLUTE linear scale retains the origin after power-off, reducing the need for repeated zero-setting during routine use. The LCD has 10 mm character height for easier reading, while MIN Hold can be used when the minimum measurement needs to be captured during an inspection procedure.
The 293-669-20 is rated IP65, providing protection against dust and coolant under the specified rating conditions. Digimatic SPC output allows measurement data to be transferred to compatible inspection and data-collection equipment.
A 75 mm standard bar, one SR44 battery and a fitted plastic case are supplied. The standard bar is used to establish the reference position before measurement.
For smaller metric parts, the Mitutoyo 293-668-20 covers 50–80 mm. For the corresponding inch-range application, the Mitutoyo 293-679-20 covers 3–4.2 inches.

Who This Product Is Best For
The Mitutoyo 293-669-20 is suitable for:
-
Oil and gas machine shops
-
Heavy-equipment repair workshops
-
Pump and compressor service companies
-
Automotive component workshops
-
Aerospace MRO teams
-
Production quality-control departments
-
Machine shops handling large metric components
-
Maintenance and inspection teams
Typical applications include measuring large pump and compressor shafts, bearing housing outside diameters, couplings, rollers, brake components, turned rings and other cylindrical parts from 75 to 105 mm.
The metric-only range makes this model suitable for applications where measurements and drawings are specified in millimetres.
How to Use / How It Works
-
Check the reference: Place the supplied 75 mm standard bar between the measuring faces.
-
Set the origin: Close the measuring faces using the ratchet and establish the reference position at 75.000 mm.
-
Open the micrometer: Use the rapid-feed mechanism to position the spindle close to the workpiece. Each rotation advances the spindle 10 mm.
-
Support the component: Support larger or heavier parts appropriately and keep the micrometer frame square to the measurement surface.
-
Take the measurement: Close the spindle using the ratchet friction thimble until the appropriate measuring force is reached.
-
Record the result: Use MIN Hold where applicable or transfer the reading through the Digimatic SPC output.
For repeat inspection work, verify the reference periodically using a suitable standard.
