Inside micrometer designed for precise internal diameter measurement, helping to capture repeatable readings with minimal fuss. Professionals and keen hobbyists gain confidence from locking and ratchet mechanisms that reduce reading errors. Is the Garosa Bore Micrometer the right choice for regular workshop inspection and calibration?
⚡ At a Glance
- • Measuring Accuracy: 0.01 mm precision across a 5–30 mm measuring range
- • Best for: Workshop technicians, machinists and hobbyists checking small internal diameters
- • Not ideal for: Measuring external dimensions or bores larger than 30 mm
Locking device and a built-in ratchet stop help secure repeatable readings. Includes a calibration ring and small wrench for straightforward adjustment.
Consistent measurements – thanks to built-in ratchet stop
Built-in ratchet stop controls spindle advance so the same contact pressure is applied for each reading, reducing variation between measures.
Reliable repeatability makes batch checks and go/no-go inspections faster, with fewer suspicious readings to remeasure.
Secure readings – with locking device
Locking device holds the measuring spindle in position once a dimension is captured, preventing accidental movement while reading or transporting.
Captured measurements remain fixed for easy recording and comparison, useful when transferring readings between bench and logbook.
Durable contact points – with alloy measuring heads
Alloy measuring heads are manufactured to fine tolerances and finished without burrs to maintain consistent contact geometry over time.
Robust contact surfaces resist wear and maintain accuracy through repeated use, reducing the need for frequent replacement.
